At the extreme ends of travel the kinetic energy is zero, but something caused it to accelerate back to the equilibrium point. We need to introduce an energy that depends on location or position. This energy is called potential ...

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.
