What Is Physics ?

Friends it is very difficult to define exactly what is physics. Physics keeps changing whenever we progress and make new discoveries. New theories bring not only new answers, while they create new questions also. And when viewed from the previous theory of physics it might not have even made sense. This makes physics more exciting and interesting. Now let me Xplore.

Physicists are trying to define physics in a generalized form. The word physics is derived from the Greek word "fuses" which means "nature". Therefore physics may be defined as a science which deals with the study of nature or natural phenomena. Now the question arises that can we explain nature, obviously not we can only feel nature and observe it. We are defining physics that physics is a science which deals with the study of nature or natural phenomena, then again the question arises that what is science?.

There are various thinking about physics, one said that physics is the study of nature or natural phenomena. In our daily life, we come across various natural phenomena e.g. the regular rising and setting of the sun, the various season in a year, the formation of clouds and blowing of winds, the heat produced by burning the coal, motion of bodies, and the moon, solar and linear eclipses, and wondrous formation of soap bubbles, etc.

According to our present knowledge of physics, it deals with matter, all types of energies, and the conversion of mass into energy. Accordingly, physics may be defined as Physics is the study of matter, energy, and its equivalence.

   Different branches of Physics:

  1. Mechanics: it deals with the theory of motion of material bodies at low speed.
  2. Thermodynamics: it deals with the theory of heat, temperature, and behaviour of a                                        system of a large number of particles (atom/molecules).
  3. Electromagnetism: it deals with the theory of electricity, magnetism and                                                          electromagnetic radiations. Read more...
Mechanics, Thermodynamics, and Electromagnetism these theories were given before 1900 and early physics called "Classical physics".
 

4. Relativity: it deals with the theory of motion of particles at high speed (of the order of speed of light). In fact, it is the theory of invariance of natural laws.

5. Quantum mechanics: it deals with the theory of mechanics of sub-microscopic particles.

The theory of Relativity and Quantum mechanics were given after 1900 and come under the head "Modern physics".
