Q12. (I ) state hooks Law for a spring. 3 (ii) Derive the equation for potential energy stored in a stretched spring.

Answered by Expert
Hooke's law states that the force needed to stretch or compress a spring by a certain distance is directly proportional to that distance.
Fs = -kx
Here, k is the constant of proportionality.
Negative sign indicates that the force is restoring force, that is, it acts in the opposite direction to the displacement of spring.
When the block is pulled by a distance x, the work done by spring force is stored as potential energy of spring
This energy is stored in the spring. Thus, an external force has to apply this energy in order to overcome the energy of spring.
