... When energy is continually added to an oscillating system, the amplitude can be increased significantly - we will look at this effect. Let’s remember, that we need an agent to apply a force that stretches or compresses a spring initially to start the dimple harmonic motion. Suppose this force is app ...

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.
