As the bicyclist rides from right to left, at which of the three points, if any, is the bicyclist’s potential energy increasing?

Question

As the bicyclist rides from right to left, at which of the three points, if any, is the bicyclist’s potential energy increasing?

Responses

The potential energy is always decreasing because the bicyclist continues to move forward.
The potential energy is increasing at point A because the bicyclist is moving fastest at that point.
The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.
The potential energy is increasing at point B because the bicyclist is highest there.

Answer 1

As the bicyclist rides from right to left, at which of the three points, if any, is the bicyclist’s potential energy increasing?

The correct response is: The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.
