Question

Gordon throws a baseball into the air. It rises, stops momentarily when it reaches its greatest height, and then falls back to the ground. At what point does kinetic energy convert to potential energy?.

Answer 1

Kinetic energy is turned into potential energy on the way up.

Step-by-step explanation:

Kinetic energy is proportional to the square of speed. As the baseball slows down, kinetic energy of the baseball decreases.

If
`g` is constant, the gain in gravitational potential energy would be proportional to the change in height. As the height of the baseball increases, the baseball gains gravitational potential energy.

As the baseball rises, its speed gradually decreases while its height increases. Kinetic energy of the baseball is turned into potential energy.

As the baseball falls back to the ground, its speed increases while its height decreases. Potential energy is turned back into kinetic energy.
