Use the picture to answer the question.
An illustration depicts a cyclist riding a bike along a hill. The end on the right where the cyclist moves upward is labeled C, the top of the hill is labeled B, and the end on the left where the cyclist moves downward is labeled A.
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 A because the bicyclist is moving fastest at that point.
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 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.
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 increasing at point B because the bicyclist is highest there.
How would potential and kinetic energy change when going down stairs one at a time versus two at a time?(1 point)
Responses
Going down stairs two at a time will give you twice as much kinetic and potential energy by the time you reach the bottom stair.
Going down stairs two at a time will give you twice as much kinetic and potential energy by the time you reach the bottom stair.
Going down stairs two at a time means you will get down in fewer steps, which saves you some kinetic and potential energy.
Going down stairs two at a time means you will get down in fewer steps, which saves you some kinetic and potential energy.
If you go down stairs two at a time, then you are going a greater distance, which will decrease your potential energy. Your kinetic energy will be less when you land on the stair.
If you go down stairs two at a time, then you are going a greater distance, which will decrease your potential energy. Your kinetic energy will be less when you land on the stair.
If you go down stairs two at a time, then your potential energy relative to the stair is greater. Your kinetic energy will be greater when you land
The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.
To determine at which point the cyclist's potential energy is increasing, we need to understand the relationship between potential energy and elevation.
Potential energy is directly related to the height or elevation of an object. The higher an object is positioned, the greater its potential energy.
Looking at the illustration, we can see that point A is at a lower elevation compared to point B, and point C is at an even higher elevation.
Therefore, as the cyclist moves from point A to point B, their potential energy will increase because they are moving to a higher elevation. Similarly, as the cyclist continues from point B to point C, their potential energy will further increase as they continue to climb uphill.
Hence, the correct answer is:
The potential energy is increasing at point A because the cyclist is increasing in elevation at that point and at point C because the cyclist is also increasing in elevation at that point.
