... • Place the block on its narrow side with, perhaps, 500 grams stacked on it. Readjust the pulley so that the cord is again parallel to the plane. Find the value of m necessary to cause the block to slide at constant speed. This will be your test to see if the frictional force has any dependence on t ...

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.
