Physics


Physics is the study of how matter and energy interact with each other and how they affect each other over time and through space. Physics functions in an exciting dimension. What we mean by this is that things keep changing in the world of physics with every discovery. As theories progress and discoveries are made, not only the answer but the whole question changes. Due to this, many individuals define physics by what it was rather than what it is and will be.

Frequently Asked Questions on Physics

Why is Physics called the King of Science?

Physics is called the king of science because it helps us understand how nature works.

Can Physics exist without Maths?

It is possible for theoretical physics to exist without Maths but it gets difficult to analyze and describe the universal phenomena without mathematical hypothesis.

How is Physics related to Biology?

Physics and Biology, when combined together, help scientists learn more about biological systems on a molecular or atomic level.

How is Physics related to Chemistry?

Physics and Chemistry may overlap when the subject under consideration is matter composed of electrons and nuclei made of protons and neutrons.

What is the importance of studying Physics?

Physics is important because it helps us understand the fundamental nature of the universe. It improves the quality of life by providing quantitative and analytical skills in fields like engineering, medicine and science.
