Kinematics is the branch of dynamics which describes the motion of
bodies without reference to the forces which either cause the motion or
are generated as a result of the motion. Kinematics is often described as
the “geometry of motion.” Some engineering applications of kinematics
include the design of cams, gears, linkages, and other machine elements
to control or produce certain desired motions, and the calculation of
flight trajectories for aircraft, rockets, and spacecraft. A thorough working
knowledge of kinematics is a prerequisite to kinetics, which is the
study of the relationships between motion and the corresponding forces
which cause or accompany the motion.
