WHAT IS PHYSICS?
The universe made up of two essential things: energy and matter. Energy, you know, the ability to do work. Matter defined as: everything that has mass and surrounds some space called matter. So you, your family, your house—in short, all the things in the universe come into account. So here is physics, defined as “a branch of science in which we study energy and matter. It tells how the objects related to each other, how they interact with each other, and how they transfer energy from one form to another.
Physics is the branch of experiments, observations, theoretical work, mathematical equations. It deals with the subatomic particles like electrons, protons, neutrons, quarks, and leptons as well as macroscopic objects like earth, stars and galaxies ETC. The most beautiful things in this science are laws and theories. like Newton laws of motion, Coloumb law, Maxwell’s equations of electromagnetism, law of thermodynamics. In theories, the most proficient theory is Einstein general and special theory of relativity. His explanation about space and time and about gravity made him a non formal physicist in the world. In my point of view, it is the most interesting field of science. it answers the every phenomenon that is occurring around the us. All the progress in the world is being possible due to it. it has major role in the present technology.
Today we can diagnose diseases, cure them, travel long distances in short time, talk with our beloved from long distances by using smartphones. In short, this is the only due to study of science, study of Physics.
BRANCHES:
It has several branches. Some of them are given below.
1) Classical Mechanics
2) Quantum mechanics
3) Electricity and magnetism
4) Nuclear Physics
5) Plasma physics
6) Atomic physics
7)Laser
8) Cosmology and relativity
9) Physics of nanotechnologies
10) Statistical mechanics
