\Kin`e*mat"ics\, n. [Gr. (?),(?) motion, fr. ? to
move.] (Physics)
The science which treats of motions considered in themselves,
or apart from their causes; the comparison and relation of
motions.
Note: Kinematics forms properly an introduction to mechanics,
      as involving the mathematical principles which are to
      be applied to its data of forces. --Nichol.
