kinematics

The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.

That part of the science of mechanics which treats of motion, its direction, velocity, acceleration, composition, etc., without reference to mass or to constraints: opposed to dynamics.

The theory of mechanical contrivances for converting one kind of motion into another, as for example for making a piston-rod with a reciprocating motion communicate to a wheel a uniform rotation. Also called applied kinematics.

The science which treats of motions considered in themselves, or apart from their causes; the comparison and relation of motions.

The branch of mechanics concerned with objects in motion, but not with the forces involved.
