Question

Derive an expression for energy stored in a streched spring

Answer 1

Answer:

Let's start with the proof. Let's start with the derivation of the above equation. Let the spring be stretched through a small distance d x dx dx. Then work done in stretching the spring through a distance d x dx dx is d W = F d x , dW=Fdx, dW=Fdx, where F is the force applied to stretch the spring.
