Question

What will happen as a result of the action in the picture?

Answer 1

• In the first picture, when the rubber band is stretched, work is done on it and energy gets stored in the stretched rubber band. This stored energy is called potential energy.
• In the second picture, when the stretched band of the catapult is released, the stored potential energy changes into kinetic energy. As a result, the stone or object placed in the catapult moves forward with speed.

Thus, the pictures show that energy can be stored in a stretched object and can later be used to produce motion.
