Question

Using the following picture, explain how the potential energy changes as the bicyclist moves from point C to B.

Answer 1

As the bicyclist moves from point C to B, the potential energy decreases. This is because point B is lower in height compared to point C. As the bicyclist descends the hill, they are moving closer to the ground and therefore experiencing a decrease in potential energy. This decrease in potential energy is converted into kinetic energy as the bicyclist picks up speed and moves downhill.
