Question

A stone is held in the rubber of a catapult, the catapult is pulled and released in a horizontal direction. In this case energy transformation takes place from __________ energy to ___________ energy.

• A. potential, kinetic
• B. potential, heat
• C. kinetic, potential
• D. kinetic, heat

Answer 1

The correct option is A potential, kinetic

The energy exerted or work done by our muscles on the rubber of the catapult is consumed in changing its shape. It gets stored in the stretched rubber as its potential energy. It is this stored energy that is used by the rubber to move to its original state, shape, and size. When the rubber is released, this stored potential energy gets converted into kinetic energy.

If a stone is stone is held in the stretched rubber of a catapult, this kinetic energy is transferred to the stone. This kinetic energy of the stone is enough to do some destructive work, like breaking a glass window, injuring someone, etc.
