The correct seence of energy transfer that occurs when an apple falls to the ground is

Result
Your answer: —  Â·  Correct: C
Explanation

The energy transfer sequence for a falling apple begins with gravitational potential energy, which is stored due to its height. As the apple falls, this potential energy is converted into kinetic energy as its speed increases. During the descent, the apple encounters air resistance, a non-conservative force that dissipates a small portion of kinetic energy as heat energy to the surrounding air. Upon impact with the ground, the remaining kinetic energy is transformed through an inelastic collision. This results in the production of sound energy and the conversion of energy into heat, which increases the temperature of both the ground and the apple. Therefore, the correct sequence is gravitational potential energy to kinetic energy, followed by heat loss to the air, and finally heat and sound energy upon impact.
