## Question:

A spring has a natural length of 20 cm. Compare the work {eq}W_{1} {/eq} done in stretching the spring from 20 cm to 30 cm with the work {eq}W_{2} {/eq} done in stretching the spring from 30 cm to 40 cm. Use {eq}k {/eq} for the spring constant.

## Spring Force

When a stretching or tensile force is applied to the spring, it tends to stretch the spring and elongates its natural length. The magnitude of the force per unit of the stretched length is called the stiffness of the spring. It is represented by the letter k.
