Kinematics Multiples
... Although the speed varies linearly with time, KE is the square of the speed, so it should be a parabola, which rules out graph B. In graph D the PE is decreasing quickly at first and then more slowly while in graph A the PE is decreasing slowly then quickly. Since the ball speeds up as it approaches ...

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.
