... the force. As long as there are no other forces, the mass’s PE will decrease as it falls and its KE will increase. At point B (y = +0.25 m), for example, the mass’s PE will have dropped to +2.5 J and its KE must have increased to 5.0 J (so that KE + PE = +7.5 J). If the mass can fall below the y = 0 ...

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.
