Physics is the branch of Science that deals with the nature and its laws. 

We have no control on natural phenomena. Every phenomenon in the universe takes place under some certain laws. Investigating these laws of the nature and arranging them in proper written format is called physics. The process of investigation these natural laws is based on the method of observations, experimentations, mathematical modeling etc. The laws of physics are generally expressed in mathematical forms. Mathematics is the language of physics.

Physics is also called as fundamental science and mother of all the branches of science. Development of all other branches of science depend on the development of physics. The development engineering and technology are based on the laws of physics.
