... 11.2 Energy in the Simple Harmonic Oscillator We get our OSE for the total mechanical energy of a simple harmonic oscillator by considering a mass attached to a spring on a horizontal, frictionless surface: E = mv2/2 + kx2/2 (here I am using x instead of s). At the equilibrium position (x=0), the e ...

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.
