Kinematics is the branch of classical mechanics which describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without looking at the cause of this motion. The term was translated from French; A.M. Ampère used the term "cinématique". He constructed the term form the Greek , kinema (movement, motion), derived from , kinein (to move). The study of "kinematics" is often referred to as the "geometry of motion."
