Physics

Physics (from Greek: physis“nature”) is a natural science that involves the study of matterand its motionthrough space-time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.

Physicsis concerned with describing the interactions of energy, matter, space, and time, and it is especially interested in what fundamental mechanisms underlie every phenomenon. The concern for describing the basic phenomena in nature essentially defines therealm of physics.
