How do forces act on objects? • An object will not start moving unless a push or pull acts on it. • Objects in motion will continue to move unless a push or pull changes that motion. • Newton’s first law is also called the law of inertia. • Inertia is the tendency of all objects to resist any change ...

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.
