Physics, the science that deals with the structure of matter and the interactions between the fundamental components of the observable universe. In the broadest sense, physics (from the Greek physikos) deals with all aspects of nature, both at the macroscopic and submicroscopic levels. His field of study covers not only the behavior of objects under the action of certain forces, but also the nature and origin of gravitational, electromagnetic and nuclear force fields. Its ultimate objective is the formulation of some comprehensive principles that bring together and explain all these disparate phenomena.
The definition of physics is the study of the physical plane of matter, motion, force and energy. The root of the word physics is Phys- and in Greek it means nature and natural order. Physics itself studies the natural world and the interactions between objects and energy in a given environment.
