Types of Variation
... Newton’s First Law states that in the absence of a net (unbalanced) force an object will persist in its original state of motion (either continue in uniform motion or remain at rest). Newton’s Second Law: the acceleration of a body varies directly as the unbalanced force acting on it and inversely a ...

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.
