Physics is a science that deals with matter and energy and their interactions.  Long called natural philosophy, physics is concerned with all aspects of nature, covering the behavior of objects under the action of given forces and the nature and origin of gravitational, electromagnetic, and nuclear force fields. The goal of physics is to formulate comprehensive principles that bring together and explain all discernible phenomena.
