What you learn in Theory:
Suppose an object is either compressed or stressed due to a force. An object is supposed to be elastic when it retains the original shape after the force is removed. The force that is applied on the object is stored as its ‘elastic potential energy’ which helps the object to restore its initial position.
What you learn in Practice:
A spring is an elastic object that is well known to all of us. It can be compressed or stretched by applying a force and the amount of stretch or compression is called the displacement. The force required to do this work is given by, Hooke’s Law as: F = kx
