... force, s, amount of elongation and k, spring constant. For example, if a mass weighing 14 pounds stretches a spring ½ foot, then 14 = k(1/2) and k = 28 lbs/ft. Before proceed to Newton’s Second Law, we define the weight, W = mg where mass is measured in slugs, grams, or kilograms. For example, g = 3 ...

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.
