Physics is often described as the study of matter and energy. It is concerned with how matter and energy relate to each other, and how they affect each other over time and through space. Physicists ask the fundamental questions how did the universe begin? how and of what is it made? how does it change? what rules govern its behavior?
Physics is described as the general scientific study of nature that aims to understand the behavior of the universe. Physics, therefore tries to explain how things happen around us or why they happen the way they do. For example, how a car moves from one point to another? Why unlike poles of magnets attract? Why does a mango fall? How is a rainbow formed? And so on.
Physics as a subject uses concepts like force, energy, mass, power among others to explain different phenomena. Energy, for example, may take the form of motion, light or electricity. In so doing, students of Physics get to learn more about matter and energy and how they interact with each other
Therefore, Physics is the study of the relationship between matter and energy.
The people who study and work professionally in this field are called physicists.
Physics is an experimental science subject, which creates theories that are tested against observations of the natural world. Theories are used to explain why things behave the way they do. This is why physicists always insist on accurate measurements and a record of results during each experiment.
Once these results are in precise mathematical forms, technologists make use of such data when designing devices such as radios, televisions, mobile phones, computers, and artificial satellites. All these things are for the betterment of human life.

The Relationship between Physics and other Subjects

Knowledge of physics is also applied in other subjects. The principles of electrostatics and particulate nature, for example, are used to explain reactions in chemistry. The tools, implements and farm machinery learnt in agriculture as well as the process of dating historical remains are applications of physics.
Physics provides the basis for biology. Without space, matter, energy and time — components that make up the universe — living organisms would not exist. Physicist Richard Feynman said that everything on earth is made of atoms, basic units of matter, that constantly move. Since biology has its foundation in physics, it applies physical natural laws to the study of living organisms, according to Muskegon Community College.

For instance, physics helps explain how bats use sound waves to navigate in the dark and how wings give insects the ability to move through the air. The American Physical Society shares that many flowers arrange their seeds or petals in a Fibonacci-like sequence to maximize exposure to light and nutrients. In some cases, biology helps prove physical laws and theories. Feynman states that biology helped scientists come up with the law of conservation of energy.

Why Study Physics?

Physics helps us to understand how the world around us works, from can openers, light bulbs and cell phones to muscles, lungs and brains; from paints, piccolos and pirouettes to cameras, cars and cathedrals; from earthquakes, tsunamis and hurricanes to quarks, DNA and black holes. From the prosaic . . . to the profound . . . to the poetic. . .

Physics helps us to organize the universe .It deals with fundamentals, and helps us to see the connections between seemly disparate phenomena. Physics gives us powerful tools to help us to express our creativity, to see the world in new ways and then to change it.

Physics provide quantitative and analytic skills needed for analyzing data and solving problems in the sciences, engineering and medicine, as well as in economics, finance, management, law and public policy.

Physics is the basis for most modern technology, and for the tools and instruments used in scientific, engineering and medical research and development. Manufacturing is dominated by physics-based technology.

Physics helps you to help others .Doctors that don’t understand physics can be dangerous. Medicine without physics technology would be barbaric. Schools without qualified physics teachers cut their students off from a host of well-respected, well paying careers.
