Physics

What is physics?

        Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity.

• Physics is a small word but it can deal the entire universe
• The word physics come from ancient greek it means "knowledge of nature".
• In the physics they are two important scientists

1. NEWTON
2. ALBERT EINSTEIN

• A scientist who specializes in the field of physics is called physicist
• This physics can divided into lot of branches
• It aims to understand how the universe works

        Physics can be classified into various branches, but classical physics is mainly concerned with energy and matter. The traditional branches of classical physics are Optics, Acoustics, Electromagnetics, and Classical mechanics. With the rapid development of physics, the scope of the subject is growing so large that it is not possible to cover physics under the above branches. A number of main branches of physics are discussed below.

• Mechanics is a branch of physics which tells about the motion of the object.
• Optics is a branch of physics which tells about the light
• Thermodynamics is a branch of physics which tells about the heat & thermal expansion and compression of the materials
• Electricity is a branch of physics which tells about the flow of electrons
• Relativity is a branch of physics which tells about the space and time. This theory was introduced by Albert Einstein.
• Acoustic is a branch of physics which tells about the sound & waves
• Magnetism is a branch of physics which tells about the magnetic lines, magnetic fields, magnetic force, etc.,..
• Quantum physics (or) Atomic physics is a branch of physics (and it comes under in the chemistry) which tells about the atomic and sub-atomic particles & the interaction based on the observation that all forms of energy are released in discrete units or bundles called "quanta"
• Nuclear physics is a branch of physics (and it comes under in the chemistry) which tells about the atomic nuclei & it tells about the nature of the particle.

further it has so many branches in it

These are the basic physics which can learn every one .
