Final answer:

When a stone is released from a catapult, the gravitational potential energy is converted into the kinetic energy of the stone, demonstrating energy conservation principles.


Explanation:

When a stone is released from a catapult, the correct energy conversion that takes place is The gravitational PE is converted into KE of the stone. This means that as the stone falls, its potential energy due to gravity is transformed into kinetic energy.

This conversion is in accordance with the principles of energy conservation and the work-energy theorem, where the initial potential energy is converted to kinetic energy as the stone moves under the influence of gravity.

Understanding these energy conversions is crucial in analyzing the motion of objects and the interplay between potential and kinetic energy in various physical scenarios.
