Physics and its Branches

Q. What is Physics?

Definition:

Physics is a branch of Physical Science that deals with the study of matter, energy and the mutual relationship between them.

Explanation:

The word "Physics" is derived from a Greek word "Physicos" which means Nature. So, basically Physics is the study of nature and nature is all made up of matter as you know everything around us is made up of matter. Physics is also know as the science of observations and experiments.

Q. How many branches of Physics are there? (explain each)

Ans:-

There are numerous branches of physics but ten major branches are explained below:

1. Mechanics: The branch of physics that deals with the study of motion in objects without reference to the cause of motion.

2. Electricity: The branch of physics that concerns the phenomenal study of stationary or moving electric charges.

3. Electro-magnetism: The branch of physics involved in study of electricity and magnetic fields.

4. Atomic Physics: The study of the structure of atom and its properties is known as Atomic Physics.

5. Solid State Physics: The branch of physics that concerns the structure, shape and other properties of solid material

6. Bio Physics: The science of the applications of the laws of physics used in biological phenomena.

7. Astro Physics: The study concerned with heavenly bodies such as planets and stars is called Astro Physics or Astronomy.

8. Quantum Physics: The fundamental branch of physics that deals with the interaction of atoms, nuclei and subatomic particles with radiation.

9. Plasma Physics: The branch of physics that deals with the study of highly charged isotopes.

10. Optics: The branch of physics concerned with the study of light and its properties.
