Answer:
Step-by-step explanation:
As the apple falls from the tree, its potential energy is converted into kinetic energy. This increase in kinetic energy is accompanied by a decrease in its potential energy. The sum of the kinetic and potential energy remains constant, but the share between the two changes. As the apple falls further, the kinetic energy continues to increase and the potential energy decreases until the apple reaches the ground, at which point the potential energy is zero and the kinetic energy is at its maximum.
