Question
As the bicyclist rides from right to left, at which of the three points, if any, is the bicyclist’s potential energy increasing?
(1 point)
Responses
The potential energy is increasing at point B because the bicyclist is highest there.
The potential energy is increasing at point B because the bicyclist is highest there.
The potential energy is always decreasing because the bicyclist continues to move forward.
The potential energy is always decreasing because the bicyclist continues to move forward.
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 C because the bicyclist is increasing in elevation at that point.
The potential energy is increasing at point A because the bicyclist is moving fastest at that point.

To determine when the bicyclist’s potential energy is increasing, we need to examine the elevation of the bicyclist at each point. Potential energy is related to height above a reference point; it increases when the bicyclist gains elevation.
1. If point B is the highest point, then the potential energy is increasing at that point because the elevation is maximized there.
2. If point C indicates that the bicyclist is moving up an incline or increasing in height, then the potential energy would also be increasing at that point due to the gain in elevation.
3. If point A is lower, the potential energy would generally not be increasing.
Given these considerations:
- The correct response is likely: **The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.**
However, if point B is indeed the highest point, then the correct answer would be about point B. Without the graphic or specific elevation details, I would choose C if it indicates an increase in height.
