... Work Demo Revisited. Have a student walk across the front of the room, carrying the 10 kg brick, at a constant speed. How much work did they do? What is the equation for the change in PE of the brick? Change in PE = PE2 – PE1 = (mgh2 – mgh1) But h2 = h1, so no PE is added or change in PE = 0. So no ...

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.
