Introduction: Physics and Matter

Physics is a study of how the universe behaves.

learning objectives

Apply physics to describe the function of daily life

Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the study of nature in an attempt to understand how the universe behaves.

What is Physics? : Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.

Physics uses the scientific method to help uncover the basic principles governing light and matter, and to discover the implications of those laws. It assumes that there are rules by which the universe functions, and that those laws can be at least partially understood by humans. It is also commonly believed that those laws could be used to predict everything about the universe’s future if complete information was available about the present state of all light and matter.

Matter is generally considered to be anything that has mass and volume. Many concepts integral to the study of classical physics involve theories and laws that explain matter and its motion. The law of conservation of mass, for example, states that mass cannot be created or destroyed. Further experiments and calculations in physics, therefore, take this law into account when formulating hypotheses to try to explain natural phenomena.

Physics aims to describe the function of everything around us, from the movement of tiny charged particles to the motion of people, cars, and spaceships. In fact, almost everything around you can be described quite accurately by the laws of physics. Consider a smart phone; physics describes how electricity interacts with the various circuits inside the device. This knowledge helps engineers select the appropriate materials and circuit layout when building the smart phone. Next, consider a GPS system; physics describes the relationship between the speed of an object, the distance over which it travels, and the time it takes to travel that distance. When you use a GPS device in a vehicle, it utilizes these physics equations to determine the travel time from one location to another. The study of physics is capable of making significant contributions through advances in new technologies that arise from theoretical breakthroughs.

Global Positioning System : GPS calculates the speed of an object, the distance over which it travels, and the time it takes to travel that distance using equations based on the laws of physics.

Physics and Other Fields

Physics is the foundation of many disciplines and contributes directly to chemistry, astronomy, engineering, and most scientific fields.

Explain why the study of physics is integral to the study of other sciences

Physics and Other Disciplines

Physics is the foundation of many important disciplines and contributes directly to others. Chemistry deals with the interactions of atoms and molecules, so it is rooted in atomic and molecular physics. Most branches of engineering are applied physics. In architecture, physics is at the heart of structural stability and is involved in acoustics, heating, lighting, and the cooling of buildings. Parts of geology rely heavily on physics, such as the radioactive dating of rocks, earthquake analysis, and heat transfer in the Earth. Some disciplines, such as biophysics and geophysics, are hybrids of physics and other disciplines.

Physics in Chemistry : The study of matter and electricity in physics is fundamental towards the understanding of concepts in chemistry, such as the covalent bond.

Physics has many applications in the biological sciences. On the microscopic level, it helps describe the properties of cell walls and cell membranes. On the macroscopic level, it can explain the heat, work, and power associated with the human body. Physics is involved in medical diagnostics, such as X-rays, magnetic resonance imaging (MRI), and ultrasonic blood flow measurements. Medical therapy sometimes directly involves physics: cancer radiotherapy uses ionizing radiation, for instance. Physics can also explain sensory phenomena, such as how musical instruments make sound, how the eye detects color, and how lasers can transmit information.

The boundary between physics and the other sciences is not always clear. For instance, chemists study atoms and molecules, which are what matter is built from, and there are some scientists who would be equally willing to call themselves physical chemists or chemical physicists. It might seem that the distinction between physics and biology would be clearer, since physics seems to deal with inanimate objects. In fact, almost all physicists would agree that the basic laws of physics that apply to molecules in a test tube work equally well for the combination of molecules that constitutes a bacterium. What differentiates physics from biology is that many of the scientific theories that describe living things ultimately result from the fundamental laws of physics, but cannot be rigorously derived from physical principles.

It is not necessary to formally study all applications of physics. What is most useful is the knowledge of the basic laws of physics and skill in the analytical methods for applying them. The study of physics can also improve your problem-solving skills. Furthermore, physics has retained the most basic aspects of science, so it is used by all of the sciences. The study of physics makes other sciences easier to understand.

Models, Theories, and Laws

The terms model , theory , and law have exact meanings in relation to their usage in the study of physics.

Define the terms model, theory, and law

Definition of Terms: Model, Theory, Law

In colloquial usage, the terms model , theory , and law are often used interchangeably or have different interpretations than they do in the sciences. In relation to the study of physics, however, each term has its own specific meaning.

The laws of nature are concise descriptions of the universe around us. They are not explanations, but human statements of the underlying rules that all natural processes follow. They are intrinsic to the universe; humans did not create them and we cannot change them. We can only discover and understand them. The cornerstone of discovering natural laws is observation; science must describe the universe as it is, not as we may imagine it to be. Laws can never be known with absolute certainty, because it is impossible to perform experiments to establish and confirm a law in every possible scenario without exception. Physicists operate under the assumption that all scientific laws and theories are valid until a counterexample is observed. If a good-quality, verifiable experiment contradicts a well-established law, then the law must be modified or overthrown completely.

A model is a representation of something that is often too difficult (or impossible) to display directly. While a model’s design is justified using experimental information, it is only accurate under limited situations. An example is the commonly used “planetary model” of the atom, in which electrons are pictured as orbiting the nucleus, analogous to the way planets orbit the Sun. We cannot observe electron orbits directly, but the mental image helps explain the observations we can make, such as the emission of light from hot gases. Physicists use models for a variety of purposes. For example, models can help physicists analyze a scenario and perform a calculation, or they can be used to represent a situation in the form of a computer simulation.

Planetary Model of an Atom : The planetary model of the atom in which electrons are pictured as orbiting the nucleus, analogous to the way planets orbit the Sun

A theory is an explanation for patterns in nature that is supported by scientific evidence and verified multiple times by various groups of researchers. Some theories include models to help visualize phenomena, whereas others do not . Newton’s theory of gravity, for example, does not require a model or mental image, because we can observe the objects directly with our own senses. The kinetic theory of gases, on the other hand, makes use of a model in which a gas is viewed as being composed of atoms and molecules. Atoms and molecules are too small to be observed directly with our senses—thus, we picture them mentally to understand what our instruments tell us about the behavior of gases.

A law uses concise language to describe a generalized pattern in nature that is supported by scientific evidence and repeated experiments. Often, a law can be expressed in the form of a single mathematical equation. Laws and theories are similar in that they are both scientific statements that result from a tested hypothesis and are supported by scientific evidence. However, the designation law is reserved for a concise and very general statement that describes phenomena in nature, such as the law that energy is conserved during any process, or Newton’s second law of motion, which relates force, mass, and acceleration by the simple equation $F=ma$. A theory, in contrast, is a less concise statement of observed phenomena. For example, the Theory of Evolution and the Theory of Relativity cannot be expressed concisely enough to be considered a law. The biggest difference between a law and a theory is that a law is much more complex and dynamic, and a theory is more explanatory. A law describes a single observable point of fact, whereas a theory explains an entire group of related phenomena. And, whereas a law is a postulate that forms the foundation of the scientific method, a theory is the end result of that process.

1.1 Physics: An Introduction

Learning objectives.

By the end of this section, you will be able to:

Explain the difference between a principle and a law.
Explain the difference between a model and a theory.

The physical universe is enormously complex in its detail. Every day, each of us observes a great variety of objects and phenomena. Over the centuries, the curiosity of the human race has led us collectively to explore and catalog a tremendous wealth of information. From the flight of birds to the colors of flowers, from lightning to gravity, from quarks to clusters of galaxies, from the flow of time to the mystery of the creation of the universe, we have asked questions and assembled huge arrays of facts. In the face of all these details, we have discovered that a surprisingly small and unified set of physical laws can explain what we observe. As humans, we make generalizations and seek order. We have found that nature is remarkably cooperative—it exhibits the underlying order and simplicity we so value.

It is the underlying order of nature that makes science in general, and physics in particular, so enjoyable to study. For example, what do a bag of chips and a car battery have in common? Both contain energy that can be converted to other forms. The law of conservation of energy (which says that energy can change form but is never lost) ties together such topics as food calories, batteries, heat, light, and watch springs. Understanding this law makes it easier to learn about the various forms energy takes and how they relate to one another. Apparently unrelated topics are connected through broadly applicable physical laws, permitting an understanding beyond just the memorization of lists of facts.

The unifying aspect of physical laws and the basic simplicity of nature form the underlying themes of this text. In learning to apply these laws, you will, of course, study the most important topics in physics. More importantly, you will gain analytical abilities that will enable you to apply these laws far beyond the scope of what can be included in a single book. These analytical skills will help you to excel academically, and they will also help you to think critically in any professional career you choose to pursue. This module discusses the realm of physics (to define what physics is), some applications of physics (to illustrate its relevance to other disciplines), and more precisely what constitutes a physical law (to illuminate the importance of experimentation to theory).

Science and the Realm of Physics

Science consists of the theories and laws that are the general truths of nature as well as the body of knowledge they encompass. Scientists are continually trying to expand this body of knowledge and to perfect the expression of the laws that describe it. Physics is concerned with describing the interactions of energy, matter, space, and time, and it is especially interested in what fundamental mechanisms underlie every phenomenon. The concern for describing the basic phenomena in nature essentially defines the realm of physics .

Physics aims to describe the function of everything around us, from the movement of tiny charged particles to the motion of people, cars, and spaceships. In fact, almost everything around you can be described quite accurately by the laws of physics. Consider a smart phone ( Figure 1.3 ). Physics describes how electricity interacts with the various circuits inside the device. This knowledge helps engineers select the appropriate materials and circuit layout when building the smart phone. Next, consider a GPS system. Physics describes the relationship between the speed of an object, the distance over which it travels, and the time it takes to travel that distance. GPS relies on precise calculations that account for variations in the Earth's landscapes, the exact distance between orbiting satellites, and even the effect of a complex occurrence of time dilation. Most of these calculations are founded on algorithms developed by Gladys West, a mathematician and computer scientist who programmed the first computers capable of highly accurate remote sensing and positioning. When you use a GPS device, it utilizes these algorithms to recognize where you are and how your position relates to other objects on Earth.

Applications of Physics

You need not be a scientist to use physics. On the contrary, knowledge of physics is useful in everyday situations as well as in nonscientific professions. It can help you understand how microwave ovens work, why metals should not be put into them, and why they might affect pacemakers. (See Figure 1.4 and Figure 1.5 .) Physics allows you to understand the hazards of radiation and rationally evaluate these hazards more easily. Physics also explains the reason why a black car radiator helps remove heat in a car engine, and it explains why a white roof helps keep the inside of a house cool. Similarly, the operation of a car’s ignition system as well as the transmission of electrical signals through our body’s nervous system are much easier to understand when you think about them in terms of basic physics.

Physics is the foundation of many important disciplines and contributes directly to others. Chemistry, for example—since it deals with the interactions of atoms and molecules—is rooted in atomic and molecular physics. Most branches of engineering are applied physics. In architecture, physics is at the heart of structural stability, and is involved in the acoustics, heating, lighting, and cooling of buildings. Parts of geology rely heavily on physics, such as radioactive dating of rocks, earthquake analysis, and heat transfer in the Earth. Some disciplines, such as biophysics and geophysics, are hybrids of physics and other disciplines.

Physics has many applications in the biological sciences. On the microscopic level, it helps describe the properties of cell walls and cell membranes ( Figure 1.6 and Figure 1.7 ). On the macroscopic level, it can explain the heat, work, and power associated with the human body. Physics is involved in medical diagnostics, such as x-rays, magnetic resonance imaging (MRI), and ultrasonic blood flow measurements. Medical therapy sometimes directly involves physics; for example, cancer radiotherapy uses ionizing radiation. Physics can also explain sensory phenomena, such as how musical instruments make sound, how the eye detects color, and how lasers can transmit information.

It is not necessary to formally study all applications of physics. What is most useful is knowledge of the basic laws of physics and a skill in the analytical methods for applying them. The study of physics also can improve your problem-solving skills. Furthermore, physics has retained the most basic aspects of science, so it is used by all of the sciences, and the study of physics makes other sciences easier to understand.

Models, Theories, and Laws; The Role of Experimentation

The laws of nature are concise descriptions of the universe around us; they are human statements of the underlying laws or rules that all natural processes follow. Such laws are intrinsic to the universe; humans did not create them and so cannot change them. We can only discover and understand them. Their discovery is a very human endeavor, with all the elements of mystery, imagination, struggle, triumph, and disappointment inherent in any creative effort. (See Figure 1.8 and Figure 1.9 .) The cornerstone of discovering natural laws is observation; science must describe the universe as it is, not as we may imagine it to be.

We all are curious to some extent. We look around, make generalizations, and try to understand what we see—for example, we look up and wonder whether one type of cloud signals an oncoming storm. As we become serious about exploring nature, we become more organized and formal in collecting and analyzing data. We attempt greater precision, perform controlled experiments (if we can), and write down ideas about how the data may be organized and unified. We then formulate models, theories, and laws based on the data we have collected and analyzed to generalize and communicate the results of these experiments.

A model is a representation of something that is often too difficult (or impossible) to display directly. While a model is justified with experimental proof, it is only accurate under limited situations. An example is the planetary model of the atom in which electrons are pictured as orbiting the nucleus, analogous to the way planets orbit the Sun. (See Figure 1.10 .) We cannot observe electron orbits directly, but the mental image helps explain the observations we can make, such as the emission of light from hot gases (atomic spectra). Physicists use models for a variety of purposes. For example, models can help physicists analyze a scenario and perform a calculation, or they can be used to represent a situation in the form of a computer simulation. A theory is an explanation for patterns in nature that is supported by scientific evidence and verified multiple times by various groups of researchers. Some theories include models to help visualize phenomena, whereas others do not. Newton’s theory of gravity, for example, does not require a model or mental image, because we can observe the objects directly with our own senses. The kinetic theory of gases, on the other hand, is a model in which a gas is viewed as being composed of atoms and molecules. Atoms and molecules are too small to be observed directly with our senses—thus, we picture them mentally to understand what our instruments tell us about the behavior of gases.

A law uses concise language to describe a generalized pattern in nature that is supported by scientific evidence and repeated experiments. Often, a law can be expressed in the form of a single mathematical equation. Laws and theories are similar in that they are both scientific statements that result from a tested hypothesis and are supported by scientific evidence. However, the designation law is reserved for a concise and very general statement that describes phenomena in nature, such as the law that energy is conserved during any process, or Newton’s second law of motion, which relates force, mass, and acceleration by the simple equation F = m a F = m a . A theory, in contrast, is a less concise statement of observed phenomena. For example, the Theory of Evolution and the Theory of Relativity cannot be expressed concisely enough to be considered a law. The biggest difference between a law and a theory is that a theory is much more complex and dynamic. A law describes a single action, whereas a theory explains an entire group of related phenomena. And, whereas a law is a postulate that forms the foundation of the scientific method, a theory is the end result of that process.

Less broadly applicable statements are usually called principles (such as Pascal’s principle, which is applicable only in fluids), but the distinction between laws and principles often is not carefully made.

Models, Theories, and Laws

Models, theories, and laws are used to help scientists analyze the data they have already collected. However, often after a model, theory, or law has been developed, it points scientists toward new discoveries they would not otherwise have made.

The models, theories, and laws we devise sometimes imply the existence of objects or phenomena as yet unobserved. These predictions are remarkable triumphs and tributes to the power of science. It is the underlying order in the universe that enables scientists to make such spectacular predictions. However, if experiment does not verify our predictions, then the theory or law is wrong, no matter how elegant or convenient it is. Laws can never be known with absolute certainty because it is impossible to perform every imaginable experiment in order to confirm a law in every possible scenario. Physicists operate under the assumption that all scientific laws and theories are valid until a counterexample is observed. If a good-quality, verifiable experiment contradicts a well-established law, then the law must be modified or overthrown completely.

The study of science in general and physics in particular is an adventure much like the exploration of uncharted ocean. Discoveries are made; models, theories, and laws are formulated; and the beauty of the physical universe is made more sublime for the insights gained.

The Scientific Method

Ibn al-Haytham (sometimes referred to as Alhazen), a 10th-11th century scientist working in Cairo, significantly advanced the understanding of optics and vision. But his contributions go much further. In demonstrating that previous approaches were incorrect, he emphasized that scientists must be ready to reject existing knowledge and become "the enemy" of everything they read; he expressed that scientists must trust only objective evidence. Al-Haytham emphasized repeated experimentation and validation, and acknowledged that senses and predisposition could lead to poor conclusions. His work was a precursor to the scientific method that we use today.

As scientists inquire and gather information about the world, they follow a process called the scientific method . This process typically begins with an observation and question that the scientist will research. Next, the scientist typically performs some research about the topic and then devises a hypothesis. Then, the scientist will test the hypothesis by performing an experiment. Finally, the scientist analyzes the results of the experiment and draws a conclusion. Note that the scientific method can be applied to many situations that are not limited to science, and this method can be modified to suit the situation.

Consider an example. Let us say that you try to turn on your car, but it will not start. You undoubtedly wonder: Why will the car not start? You can follow a scientific method to answer this question. First off, you may perform some research to determine a variety of reasons why the car will not start. Next, you will state a hypothesis. For example, you may believe that the car is not starting because it has no engine oil. To test this, you open the hood of the car and examine the oil level. You observe that the oil is at an acceptable level, and you thus conclude that the oil level is not contributing to your car issue. To troubleshoot the issue further, you may devise a new hypothesis to test and then repeat the process again.

The Evolution of Natural Philosophy into Modern Physics

Physics was not always a separate and distinct discipline. It remains connected to other sciences to this day. The word physics comes from Greek, meaning nature. The study of nature came to be called “natural philosophy.” From ancient times through the Renaissance, natural philosophy encompassed many fields, including astronomy, biology, chemistry, physics, mathematics, and medicine. Over the last few centuries, the growth of knowledge has resulted in ever-increasing specialization and branching of natural philosophy into separate fields, with physics retaining the most basic facets. (See Figure 1.11 , Figure 1.12 , and Figure 1.13 .) Physics as it developed from the Renaissance to the end of the 19th century is called classical physics . It was transformed into modern physics by revolutionary discoveries made starting at the beginning of the 20th century.

Classical physics is not an exact description of the universe, but it is an excellent approximation under the following conditions: Matter must be moving at speeds less than about 1% of the speed of light, the objects dealt with must be large enough to be seen with a microscope, and only weak gravitational fields, such as the field generated by the Earth, can be involved. Because humans live under such circumstances, classical physics seems intuitively reasonable, while many aspects of modern physics seem bizarre. This is why models are so useful in modern physics—they let us conceptualize phenomena we do not ordinarily experience. We can relate to models in human terms and visualize what happens when objects move at high speeds or imagine what objects too small to observe with our senses might be like. For example, we can understand an atom’s properties because we can picture it in our minds, although we have never seen an atom with our eyes. New tools, of course, allow us to better picture phenomena we cannot see. In fact, new instrumentation has allowed us in recent years to actually “picture” the atom.

Limits on the Laws of Classical Physics

For the laws of classical physics to apply, the following criteria must be met: Matter must be moving at speeds less than about 1% of the speed of light, the objects dealt with must be large enough to be seen with a microscope, and only weak gravitational fields (such as the field generated by the Earth) can be involved.

Some of the most spectacular advances in science have been made in modern physics. Many of the laws of classical physics have been modified or rejected, and revolutionary changes in technology, society, and our view of the universe have resulted. Like science fiction, modern physics is filled with fascinating objects beyond our normal experiences, but it has the advantage over science fiction of being very real. Why, then, is the majority of this text devoted to topics of classical physics? There are two main reasons: Classical physics gives an extremely accurate description of the universe under a wide range of everyday circumstances, and knowledge of classical physics is necessary to understand modern physics.

Modern physics itself consists of the two revolutionary theories, relativity and quantum mechanics. These theories deal with the very fast and the very small, respectively. Relativity must be used whenever an object is traveling at greater than about 1% of the speed of light or experiences a strong gravitational field such as that near the Sun. Quantum mechanics must be used for objects smaller than can be seen with a microscope. The combination of these two theories is relativistic quantum mechanics, and it describes the behavior of small objects traveling at high speeds or experiencing a strong gravitational field. Relativistic quantum mechanics is the best universally applicable theory we have. Because of its mathematical complexity, it is used only when necessary, and the other theories are used whenever they will produce sufficiently accurate results. We will find, however, that we can do a great deal of modern physics with the algebra and trigonometry used in this text.

Check Your Understanding

A friend tells you they have learned about a new law of nature. What can you know about the information even before your friend describes the law? How would the information be different if your friend told you they had learned about a scientific theory rather than a law?

Without knowing the details of the law, you can still infer that the information your friend has learned conforms to the requirements of all laws of nature: it will be a concise description of the universe around us; a statement of the underlying rules that all natural processes follow. If the information had been a theory, you would be able to infer that the information will be a large-scale, broadly applicable generalization.

Physics Essay Topics

Choosing an appropriate essay topic is one of the most important but also toughest decisions that undergraduate students make while at university. Many students believe that a well-written and well-researched essay will positively contribute to their final grade. Of course, this is true; however, university essays represent a lot more than just a good grade as they enable students to guide and facilitate their own academic and professional development.

For example, a well-defined and appropriate essay topic will allow students to demonstrate that they are capable of identifying their own area of interest by using effective and specialised research tools. In addition, the ability to explore a specific idea and to manage the related research processes within a given time interval is often considered as an objective indication of the students’ capacities and strengths as future researchers.

As a result, and regardless of their discipline, it is essential for students to be aware of the current trends and attitudes in their academic field, and thus become eligible and capable of defining an effective essay research question that is suitable to their own skills and research targets. This is especially true in physics, a broad field that encompasses a wide variety of systems and scientific theories.

Physics deals with the interaction of matter and energy and attempts to understand how these interacting systems function and, eventually, to gain a greater insight regarding how the universe behaves. Therefore, the following lines present several physics essay topics that will help guide and prepare physics students for this process. For simplicity, these topics are divided into the following five categories: 1) Photonics, Lasers and Nonlinear Optics, 2) Astrophysics, 3) Solid-state physics, 4) Theoretical Physics, and 5) Electromagnetism. It should be noted that there are many more branches and sub-branches of Physics, each with each own significance and applications. Therefore, undergraduate students should not be limited by the following examples. Instead, these essay topics should act as an incentive for students to explore their options and choose an essay that adjusts to their own academic goals and incentives.

Photonics, Lasers and Nonlinear Optics Topics

Astrophysics essay topics, solid-state physics essay topics, theoretical physics essay topics, electromagnetism essays.

With applications ranging from optical computers and ultrafast switches to DNA sequencing, consumer electronics manufacturing, the field of photonics, lasers and nonlinear optics offers physics students the opportunity to enter an exciting high tech career path. Photonics and nonlinear optics examine and utilise light behaviour and generation in different media, whereas laser (light amplification by the stimulated emission of radiation) science is the branch of optics that describes and exploits phenomena in lasers.

Astrophysics is the branch of physics that seeks to understand how the universe works and explain phenomena such as the life and death of stars, black holes, gravitational anomalies, astronomy, cosmology, celestial and galactic observations, and so many others. In fact, one could simply describe this field as the study of everything beyond our planet. However, in this process of understanding the Universe, astrophysics has very important terrestrial applications as well in medicine, life-science industry, environmental monitoring, etc.

Solid-state physics is the scientific field that investigates the macroscopic and microscopic properties of solids and condensed matter such as metals, semiconductors, and insulators for the development of novel technological applications. This branch of physics is often considered to be more related to chemistry than some other branches of physics. However, solid-state physics forms the theoretical basis for material physics and it is a fundamental component of modern electronics.

15 basic physics concepts to help you understand our world

Physics is the science that quantifies reality. Its influence extends to all the natural sciences, including biophysics, astronomy, and chemistry. Physics classifies all interactions between matter and energy and tries to answer the most central questions of the universe. From Aristotle and Isaac Newton to Marie Curie, philosophers and scientists have been using physics to understand the world for at least 2,000 years.

In any field, a scientist needs a handle on the basics before finding answers to fundamental questions. In physics, different types of matter-energy interactions define the basic branches of the sciences. Energy takes the form of heat, light, radiation, sound, motion, and electricity. It can be stored in an object’s position, chemical bonds, physical tension, and atomic nuclei. Matter refers to anything with mass, or anything made up of atoms, that takes up space. From the bonding of atoms to the combustion of an engine, matter and energy interact in all facets of life, defining the physical world.

As current and former students are aware, physics makes sense of the relationships between matter and energy through mathematics; although, an appreciation for how physics shapes the world doesn’t require advanced computational skills. Stacker used a variety of scientific and educational resources to compile a list of basic physics concepts to help explain how the world works. From Newton's Laws of Motion to electric forces, these concepts explain why matter behaves the way it does.

Read on to see how physics allows engineers to develop life-saving technology like airbags, how it explains door knob placement, and why a person’s legs look so short when they’re standing in water.

One of the first lessons in a physics class is that of motion: how an object moves, how fast it moves, where it moves, and at what rate it speeds up and slows down.

Physicists commonly use velocity and acceleration to characterize motion. Velocity refers to motion in a specific direction, while acceleration measures how quickly or slowly velocity changes. For example, when driving somewhere, both a driver and a car have velocity, meaning they move in a specific direction at some speed. Said driver probably changes how fast they travel from time to time, alternately accelerating and decelerating.

Newton’s first law

Nothing moves without a little push first. That’s essentially Isaac Newton’s first law of motion. If an object is moving at a constant speed (even if the speed is zero, and the object is stationary), it will stay that way unless a force, like the friction between a wheel and the ground, affects it. This concept is also called inertia. Newton’s first law explains why once a rocket is launched into the vacuum of space , without the resistance of air or other forces, it will keep traveling in a straight line at a constant speed indefinitely.

Newton’s second law

As alluded to in Newton’s first law, in order to move, an object needs a force. Generally, a force is a push or pull. For example, the front door needs a push before it can open. Newton’s second law asserts that a force depends on the mass of an object exerting that force and its acceleration. Quickly pushing a hand forward to open the door will create a much more forceful entrance than if the same person slowed their approach.

Newton’s third law

Forces don’t act in isolation; each is always accompanied by another force that pushes or pulls in the opposite direction . When pushing a chair across the floor, for example, not only does one exert a force that moves the chair, but the floor exerts another force—friction—opposing the push. Some examples of Newton’s third law in action include a car’s wheels push backward on the ground, making use of the road’s friction force and moving forward; or a bird’s wings push air down and back to generate lift and fly forward.

Most famous as the force that makes things fall down, more fundamentally, gravity is a force of attraction. Not only does it attract things to Earth’s surface, but it keeps planets orbiting stars. Gravity is also the reason things have weight. Everything has mass, a measure of the amount of matter in an object, but the force of Earth’s gravitational pull is what creates weight .

Centripetal force

The low-speed limits posted for on and off-ramps are there for a reason: centripetal force. When something accelerates along a circular path, centripetal force keeps it going in the circle . For curved exit ramps, the speed limits have been specially calculated to ensure that centripetal force keeps the car on its path.

Work and energy

Work happens whenever a force moves something . Whenever someone does work on another object, like moving a chair across the floor, they also transfer energy to that object. In this case, the person moving the chair gives it kinetic energy—the energy of motion.

This is part of the law of conservation of energy: Energy cannot be created nor destroyed but can be transferred to different objects and take different forms. This concept helps explain how fuel and engines work, and why car owners need to buy gasoline or charge their vehicles. When a driver starts up their car, the car doesn’t create kinetic energy to move; instead, the chemical or potential energy in the fuel of the car combusts in the engine to generate motion, converting potential energy into kinetic energy.

Some may think of momentum as that motivated, “on a roll” feeling that follows a series of successes. In physics, momentum is how much motion something has. It’s similar to the colloquial meaning, in that an object’s physical momentum determines how much force is needed to stop a moving object that’s “on a roll.” Impulse measures how much momentum changes over time.

These concepts help engineers design airbags, which increase the impulse—or time required to stop the momentum—of a driver during a crash. This means that the driver feels a smaller force from the crash, as they experience the change in momentum over a longer period of time .

Torque is the reason doors have knobs and hinges on opposite sides and is the force that causes an object to rotate or twist about an axis. It requires more force to rotate an object when pushing closest to the axis of rotation, which is why doorknobs are nearly as far as possible from the hinges.

Simple harmonic motion

Simple harmonic motion involves oscillations , like a block bouncing up and down on a spring, or a pendulum swinging left, right, and back again. With this kind of movement, an object passes through a central position to one side and then moves the same amount to the other side after each pass through the center so that maximum displacement is equal on both ends.

In the pendulum example, the pendulum swings just as far left as it does right. It’s called harmonic motion because musical sounds are combinations of simple harmonic waves, sound waves emitted by musical instruments.

Fluid dynamics

From river flow to wind patterns, fluid dynamics explains some of the most common forces of nature. Physicists and engineers study flow rates of fluids, type of flow (like smooth or turbulent), friction, pressure, fluid thickness, and more to understand liquids and gases. Anyone with air travel experience has benefitted from the study of fluid dynamics. The shape of airplane wings takes advantage of airflow, the curved top and flat bottom manipulating air pressure to lift the plane.

Thermodynamics

Thermodynamics regards different kinds of heat and energy transfer. Heat is a form of energy and can transfer from a hot object or area to a cooler one through radiation, physical contact, or the flow of heated particles known as convection. Heat represents energy transferred between systems because of a temperature difference, while temperature measures how fast atoms are moving.

Thanks to thermodynamics, scientists and engineers have created air conditioning, central heating, and computers that don’t overheat. Biologists also benefit from this field: Thermodynamics governs how organisms receive, store, and expend energy. For example, plants take in heat energy in the form of the sun’s radiation and animals emit heat during energy metabolism.

Electricity

Electricity exists thanks to positive and negative charges, largely carried by two subatomic particles: protons, which are positively charged, and electrons, which are negatively charged. Opposite charges attract each other, while like charges repel. Whenever one of these charged particles moves, it creates an electrical current.

Every time someone turns on a light, electrons move from an area of negative charge through a wire toward an area of positive charge, generating a current to power the bulb. Electricity isn’t just useful for appliances , though, it also plays a fundamental role in biology, powering animals’ nervous systems. Neurons communicate with the help of electrically charged atoms, or ions, generating electrical impulses that power things like muscle movement.

The motion of electric charges creates current and generates an electromagnetic force, resulting in magnetism. Like charges, magnets consist of two opposite components. These components, called poles, are also similar to charges in that like poles repel while opposites attract. Each magnet has a north and south pole. Earth also has magnetic poles, though their location isn’t quite the same as the more popular geographic north and south poles. Scientists think that Earth’s swirling, metallic core creates the planet’s magnetic field, making Earth a giant magnet.

Eyeglasses, contact lenses, microscopes, movie projectors, cameras, and more all exist because of the physics of light, or optics. These innovations harness the principle of refraction or the angle at which light bends when entering a different material. For example, glass lenses—similar to the lens of an eye—use refraction to focus and magnify images. Refraction also creates the strange image of a disproportionately squat lower half when a person stands waist-deep in a pool. Light travels slower in water , so the human eye gazing at the pool from above perceives objects in water as closer than they actually are.

Newton’s Laws of Motion

Newton’s Law is One of the Most Important Physics Topics. Newton’s Law of Motion consists of three laws, based on which all things related to motion can be known. Newton’s law of motion consists of three laws. From these laws, we can know all things related to motion.

The first law of Newton’s law states Uniform Motion and is also called the Law of inertia. In the second Newton’s Law, the force is said to be, which is directly proportional to the square of acceleration. And in the third Newton’s law, it is said that every action has an equal and opposite reaction.

These three newton’s law of motion is a very important part of physics topics. If you are studying physics, then definitely read this topic, if any problem arises, you can take help related to physics assignments and homework from our experts.

Vectors and Projectiles

Vectors and Projectiles are one of the third most important physics topics. Vectors and projectiles both have different meanings, but they are related to each other, only then they are considered to be the same topic.

Arrows represent vectors. The length of the Arrow is Proportional to the Magnitude, and the Direction of the Arrow is to be the Direction of the Vector that defines the vector. And projectile means that after throwing any object, it goes down due to gravity.

This is a very interesting topic, if you are a student of physics, then you must read this topic, and if you need help with any assignment or homework related to it, then you can take it from our experts.

Work and Energy

Work and energy are the two words that we often use in everyday life, but this is a very important physics topic. Work and energy have different meanings in physics.

Work means that energy is transferred by force, and energy means the ability to work. Each other’s words are fulfilling the meaning of these two. It is a very interesting physics topic, on top of which you can also write many assignments.

Circular Motion and Gravitation

Circular Motion and Gravitation are very interesting physics topics. It is said that forces can be used in circular motion and gravitation.

Circular motion means when a body moves in a circular path at a content speed and constant direction. And gravitation means that if we throw an object upwards, that object will go back to the top of the force according to the Cause of Gravity.

Electric circuits are one of the physics topics that tell us in detail about electric circuits. Both positive and negative are electric field circuits. This is explained by what works and how they work.

Electric circuits refer to the positive current coming out of a cell and generator with a wire connected to the negative circuit with the help of a wire. This is a very interesting chapter for physics students and can also offer many models and assignments on this topic.

Thermal physics is also a very important part of physics topics. Thermal physics is a topic that exposes students to many new things.

The study of thermal physics is done by heat. Heat energy and thermal energies are the motions and vibrations of molecules in terms of the energy activity of any substance or system. If there are more molecules in it, the same energy will be found in it. This is a very interesting topic for students, and many assignments can be made on it.

Vibrations and Waves

Vibrations and Waves On hearing this word, your mind must have heard thoughts related to the sound. But vibrations and waves are also part of physics topics. Vibrations and waves are very important in physics. Also, know How do convex mirrors impact your reflection?

Vibrations mean that if we shake with a big pay force, then that body keeps vibrating for some time due to that force, that vibration is called vibration. A wave can be described as a disturbance that travels from one medium to another through a medium. They are both from advance quantum physics , and students can make many models and assignments on them to get the aim of physics.

Refraction and Lenses

Refraction and lenses are some of the most interesting and important physics topics. All this topic is based on refraction and lenses. Students need to know how light lanes affect refraction through their theoretical physicist.

We can determine whether the light will reflect or refract by placing the ray of light on the lens in the refraction and lenses. It is also one of the interesting topics for the students, and with the help of this topic, students can also make many physics assignments.

How is physics used in daily life?

Physics captures our daily life. It explains the motion, forces, and internal energy behind ordinary works. For example, various actions like driving a car, walking, or using a phone call include advances in physics.

Let’s understand it through examples-

1. Example of heat

Heat is a kind of energy that carries from a warm object to a cold object. For example, when you use the stove for cooking, the flame transfers the heat to the utensil put on top of it. As a result, food gets heat from utensils. Physical optics must account for the more subtle properties of visible light in its waveform.

2. Example of a ballpoint pen

The use of a ballpoint pen is inevitable whether you are in school or at the workplace. If physics is not there, then you are not able to write on paper. The physics topics of gravity come when we talk about writing through a ballpoint pen.

As you press the pen on the paper to write, the ball turns, or gravity pushes the ink down on the ball top, from where it is transferred to the paper.

Useful point for students-

Essays in Physics: Thirty-two thoughtful essays on topics in undergraduate-level physics

Cite Icon Cite
Permissions Icon Permissions

“Essays in Physics” gives accounts of 32 chosen topics. The level is that of a 3–4-year university course in Physics. The topics discussed are diverse but “mainstream”. Each essay aims to say something fresh that complements what the reader will find elsewhere. Just what “fresh” means inevitably depends somewhat on the subject matter. Some chapters give a “different” slant on a familiar idea (e.g. electromagnetic energy, Lorentz transformation, photon emission). Some contain an analysis not available elsewhere (diffraction, feedback stability). Some correct material that is commonplace in many textbooks (much atomic physics). Some add insightful discussion to standard material (free energy, Brillouin zones). One in particular refines technique (perturbation theory). One brings order to confusion (- m d B ). The aim in all cases is to encourage a fuller, and correct, understanding, and an enhanced intellectual acuity (critical faculty). With a subject as mature as physics, it is bold to claim originality. However I will dare to make that claim, in particular for Chapters 10, 22 and 30, but also for parts of most other chapters.

Scientific Methods

Physical Science

Physical science is a broad term encompassing the various branches of natural science that study non-living systems. Physical science comprises four general areas: physics, astronomy, chemistry, and the Earth sciences. Each of these is, in turn, split into fields and subfields. This article examines the historical development, scope, principal concerns, and methods of Physical Science.

Basic Principles of Physical Sciences

The physical science’s foundations lie upon fundamental theories and concepts, each of which describes and models a certain aspect of the behaviour of nature. As with other sciences, these pivotal theories and concepts were discovered using the scientific method . In the next few sections, let us go through the basic principles of the four branches of Physical Science.

Basic Principles of Physics

Physics is a fundamental science because other natural sciences deal with systems that obey physics laws. The physical laws of energy, matter, and nature’s forces govern the interactions between particles, such as atoms and molecules. Some basic principles of physics are:

Newton’s Laws of Motion
Gravity Theory
Work, Energy and Power
Force, Mass and Weight
Energy Conversion, Transfer and Conservation
Thermodynamics Laws

Understand the Laws of Motion and the concepts behind these theories by watching this intriguing video.

Basic Principles of Chemistry

Chemistry is notably known as the science of matter, specifically at the micro-level. It mainly deals with compounds and elements, and the formation of atoms, molecules, and ions. Chemistry also studies the composition, structure, behaviour, properties, and the changes that compounds and elements undergo during a reaction with other substances. The study of Chemistry mainly includes the following:

Water and its properties
Nuclear Chemistry
Organic Chemistry
Atomic Theory
Quantum Mechanics Principle

Basic Principles of Astronomy

Astronomy is the science of heavenly bodies and their interactions in space. Its studies mainly entail the following:

The origin of the universe, the most commonly accepted scientific theory of the origin of the universe is the Big Bang Theory.
The Solar System, specifically Earth in the Solar System
The measurement of Time
The features and composition of the Moon
The interactions between the Moon and the Earth
The characteristics of stars and galaxies

Watch the video and discover the secrets hiding among the stars.

Basic Principles of Earth Science

Earth science is the study of the planet Earth, the only life-bearing planet in the solar system. Its studies mainly include:

Soil Science
Rocks and Minerals
Earth’s Atmosphere
Earth’s Tectonic Structure

Importance of Physical Science in our Daily Life
