Question

24. A spring of spring constant k is stretched by distance r. Obtain formula for
elastic potential energy of a stretched spring. Plot graph of energies versus
distance​

Answer 1

Answer:

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object. Many objects are designed specifically to store elastic potential energy, for example:

The coil spring of a wind-up clock

An archer's stretched bow

A bent diving board, just before a divers jump

The twisted rubber band which powers a toy airplane

A bouncy ball, compressed at the moment it bounces off a brick wall.

An object designed to store elastic
