How does the study of physics made a milestone for the world? And how does it help me in my daily life? Physics is the science of matter and its motion, space-time and energy. Physics describes many forms of energy – such as kinetic energy, electrical energy, and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration if it is said that Nature is almost Physics (apart from the fact that the word Physics itself is derived from Greek “physis” meaning nature). Physics is all around us.
