An object is attached to a vertical spring and bobs up and down between points A and B.Where is the object located when the elastic potential energy of the system object-spring is a minimum?

Question

Quizplus · Accepted Answer

The elastic potential energy of a spring system is minimum when the spring is neither stretched nor compressed, which occurs at the equilibrium position. This position is midway between the two extremes of the object's motion (points A and B), where the spring force balances the gravitational force.
