Physics

Physics (from Ancient Greek: φυσική (ἐπιστήμη), romanized: physikḗ (epistḗmē), lit. “knowledge of nature”, from φύσις → phýsis, “nature”) is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force.

Physics is the science that has for object of study the natural phenomena and for the purpose of their general laws by applying the scientific method. Originally a branch of philosophy, physics was called natural philosophy at least until the eighteenth century; only after the codification of the scientific method by Galileo Galilei, and thanks to continuous developments and discoveries in the scientific field, the term “physics” has been definitively distinguished from that of philosophy.
