Question

describe the expression of potential energy in spring?

Answer 1

 Work done by the external force in compressing the spring from x = 0 to x = L can be obtained by:

 is the energy given by the external force to the spring with an extension x. 

This energy is stored as potential energy in the spring.

Hope it helps u ☺

Answer 2

Elastic potential energy is Potential energy stored as a result of deformation of an elastic object , such as the stretching of a spring . It is equal to the work done to stretch the spring , which depends upon the spring constant k as well as the distance stretched.

hope it helps you
