Here's a breakdown:
* Gravitational Potential Energy: This is the energy an object possesses due to its position in a gravitational field. The higher the object, the more gravitational potential energy it has.
* Kinetic Energy: This is the energy of motion. As the rocks fall, their speed increases, and thus their kinetic energy increases.
The energy transformation:
1. At the top of the mountain: The rocks have maximum gravitational potential energy and minimum kinetic energy (as they are stationary).
2. As they fall: Gravitational potential energy is converted into kinetic energy.
3. Just before hitting the ground: The rocks have minimal gravitational potential energy and maximum kinetic energy.
Factors influencing the energy:
* Mass of the rock: Heavier rocks have more energy.
* Height of the mountain: The higher the mountain, the more gravitational potential energy the rocks have initially.
* Air resistance: Air resistance will slow the rocks down, reducing their final kinetic energy.
Important Note: The total energy (potential + kinetic) remains constant throughout the fall, assuming no energy loss due to friction or air resistance. This is a key principle of conservation of energy.
