The kinematical discussion begins with the consideration of motion along a continuous line, curved or straight.
Obviously the number of such geometrical or kinematical definitions is infinite.
For applications of the hodograph to the solution of kinematical problems see Mechanics.
This is because the steering of the tricycle depends on a kinematical, that of the Otto on a dynamical principle.
kinematics kin·e·mat·ics (kĭn'ə-māt'ĭks)
The branch of mechanics dealing with the study of the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.
The branch of physics that deals with the characteristics of motion without regard for the effects of forces or mass. Compare dynamics.
