... It’s interesting to note that when a wheel rolls without slip, there is one point in contact with the surface which is stationary meaning the frictional force which keeps the wheel rotating is the static frictional force. The condition for rolling with slip is more complicated and is best solved by ...

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.
