Question

Spring constant of a spring is 50N/M . It is stretched through a distance of the centimetres what will be potential energy stored in the spring​

Answer 1

Explanation:

Work is done when a spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic distortion has not happened, the work done is equal to the elastic potential energy stored.

The elastic potential energy stored can be calculated using the equation:

elastic potential energy = 0.5 × spring constant × (extension)2

This is when:

elastic potential energy (Ee) is measured in joules (J)

spring constant (k) is measured in newtons per metre (N/m)

extension, referring to the increase in length, (x) is measured in metres (m)

This equation also works for the reduction in length when a spring is compressed.

Example

A spring has a spring constant, k, of 3 N/m.
