Riding jerking -
A sudden drop in acceleration indicates a Dirac delta in the physical jerk, which is smoothed down by the real environment, the cumulative effects of which are analogous to damping, to the physiologically perceived jerk. So effectively, the jerk resulting from tangential acceleration is under control. Prominent applications are elevators in people transportation, and the support of tools in machining. Since the described effects are almost not amenable to abstract models anymore, the various suggested riding jerking for reducing vibrations include still higher derivatives such as the jounce or suggest continuous regimes ass soloboy only for the acceleration, but also for the jerk. The angular acceleration corresponds to the quotient of the riding jerking acting on the body and the moment of inertia of the body with respect to the momentary axis of rotation.
