Part I: Centripetal force from the rotational motion
... The apparatus, see figure ( 2 ), consists of an electric motor that rotates the centripetal force apparatus. As the apparatus rotates, the inertia of the mass m moves it away from the center. At a measured distance from the center of rotation, the mass contacts a pivoted pointer P. When the pointer ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
