... If an object speeds up, slows down, or changes direction, the objects is accelerating. Acceleration occurs because a force acts upon an object, causing the object to change its speed or direction. Recall that a force is a push or pull. Acceleration can also be described as a change in velocity. Any ...

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.
