Answer 1

The correct response is:

The potential energy of the ball decreases, and the kinetic energy of the ball increases.

As the ball rolls down the hill, it loses height, resulting in a decrease in potential energy, while its speed increases, resulting in an increase in kinetic energy. This conversion between potential and kinetic energy illustrates the principle of conservation of energy.
