Question

Give reasons why A deformed spring possesses potential energy.

Answer 1

Dear Student,

◆ Answer with explaination -

• Spring is an elastic material.
• Work is done while deforming (compressing/stretching) the spring through some displacement by external force. W = F.s
• This work is stored in the form of energy due ti elasticity of the string.
• This is called elastic potential energy of spring.
• Hence, deformed spring possess potential energy.

Hope that helps you...

Answer 2

Explanation:

Spring potential energy is calculated by Hooke’s law. The potential energy is a work done by spring.

Work is product of "force and distance" travelled by the spring from its mean position. By integrating it the potential energy is equal to $\frac{1}{2} k x^{2}$.

Hence, the value is not 0 because the constant is not zero and also the displacement is there due to deformation. So a deformed spring always contains an integral value of potential energy.
