# AP Physics - Equilibrium

posted by henry

Describe several situations in which an object is not in equilibrium even though the net force on it is zero.

I can't think of a single one. I can think of the opposite (equilibrium with net force not being zero) but I don't get it the other way around. Can someone explain?
