Spring Potential Energy

A light spring is vertical and a mass less pan is attached to it. Force constant of the spring is k. A block of mass m is gently dropped on the pan. Plot the variation of spring potential energy, gravitation potential energy and the total potential energy of the system as a function of displacement (x) of the block. For gravitational potential energy take referece level to the initial postion of the pan.

A long spring is stretched by 2 cm having potential energy as V. If the spring is stretched by 10 cm, the potential energy would be

On pressing a spring its potential energy ………….. (remains constant, increases, decreases)

Assertion: A spring has potential energy , both when it is compresed or stretched. Reason: In compressing or stretching, work is done on the spring against the resotoring force.
