Question

The elastic potential energy of a body is

Answer 1

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object.

I hope it helps u dear☺️....

Answer 2

equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched...
