... When an object is moving in a circle or circular arc (part of a circle) with constant speed it is said to be in uniform circular motion. There are many everyday examples of this type of motion: a car travelling around a corner or curve, a person on a merry-go-round or a satellite orbiting the Earth. ...

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.
