Question

The elastic potential energy stored in a spring of force constant k is

Answer 1

Answer:

x=displacement of spring from mean position

k=force constant of spring

F=Force applied on spring

F=kx

Elastic potential energy stored in spring(E)=Fdx

dE=kxdx

(integration)dE=(integration)kxdx

E=kx^2/2

E=1/2×k×x^2

Answer 2

Answer:

Elastic potential energy is the potential energy stored by stretching or compressing an elastic object by an external force such as the stretching of a spring. It is equal to the work done to stretch the spring which depends on the spring constant k and the distance stretched.
