1. A rubber band stretching: When you pull on a rubber band, it stretches and stores energy. This stored energy is due to the elastic force within the rubber band. When you release the rubber band, the elastic force causes it to snap back to its original shape.

2. A spring compressing: When you push down on a spring, you compress it. This compression stores potential energy within the spring. The elastic force resists the compression and wants to return the spring to its original length. When you release the spring, the elastic force causes it to spring back to its original position.

3. Bouncing a ball: When you drop a ball, it deforms slightly upon impact with the ground. This deformation is due to the elastic force of the ball's material. The stored energy in the ball's deformation is then released, propelling the ball back upwards.

These are just a few examples of elastic force in action. Elastic forces are important in many everyday objects and systems, from playground equipment to car suspensions.
