kinematics n 1: the branch of mechanics concerned with motion without reference to force or mass
Kinematics \Kin`e*mat"ics\, n. [Gr. (?),(?) motion, fr. kinei^n to move.] (Physics) The science which treats of motions considered in themselves, or apart from their causes; the comparison and relation of motions. [1913 Webster] Note: Kinematics forms properly an introduction to mechanics, as involving the mathematical principles which are to be applied to its data of forces. --Nichol. [1913 Webster]
