Whenever the shape and/or size of a body changes, the cause may be a pair of forces. Give an example, identifying the pair of the forces in each case. How do their magnitudes and direction compare?
There is a change in the shape and size of a spring stretched by a weight hanging from it.
The downward weight increases the length of the spring but the restoring force in the spring acting upwards restricts it. In the equilibrium position, the two forces are equal in the magnitude but opposite in direction.
