Experiment 7: Conservation of Energy
... Consider a body of mass m, being accelerated by a compressed spring. As you verified in the first experiment of the semester, the force exerted by a spring is given by Hooke’s Law, F = -kx. Thus, from Equation 2, the change in potential energy as a spring is stretched or compressed is: Z xf ...

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.
