What energy transformation occurs during a high dive from a platform?

1. Gravitational potential energy transforms into thermal energy

2. Gravitational potential energy transforms into kinetic energy

3. Kinetic energy transforms into gravitational potential energy

4. Thermal energy converts into mechanical energy

The correct answer is: Gravitational potential energy transforms into kinetic energy

During a high dive from a platform, the diver begins with gravitational potential energy due to their height above the water. As they dive, this potential energy is converted into kinetic energy as they fall. The gravitational force acts on the diver, causing them to accelerate downward, which increases their speed and, consequently, their kinetic energy. At the start of the dive, the gravitational potential energy is at its maximum, and as the diver descends, this potential energy decreases while the kinetic energy increases, illustrating the transformation from one form of energy to another in a typical gravitational field scenario. This process continues until the diver reaches the water, at which point the kinetic energy is at its highest just before impact. Thus, the correct answer accurately reflects the primary energy transformation occurring during the dive.
