Select all choices that accurately describe the stored potential energy of the football based on its position. Assume the scenario has no friction applied. (7-PS3-2)

Question

Position A has a greater potential energy than Position C
Position C has a greater potential energy than Position A
Position B has a greater potential energy than Position A
Position B has a greater potential energy than Position C

Answer 1

To accurately describe the stored potential energy of the football based on its position, we need to consider the gravitational potential energy, which is influenced by the height of the object above a reference point (usually the ground).

Assuming:

• Position A is at a certain height,
• Position B is at a greater height than Position A,
• Position C is at a lower height than Position A,

Given these assumptions, the following choices would be true:

1. Position A has a greater potential energy than Position C - This is true if Position C is lower than Position A.
2. Position B has a greater potential energy than Position A - This is true if Position B is at a higher position than Position A.
3. Position B has a greater potential energy than Position C - This is true if Position B is higher than both Position A and Position C.

Based on the assumptions made about the relative heights of the positions, the correct choices would be:

• Position A has a greater potential energy than Position C
• Position B has a greater potential energy than Position A
• Position B has a greater potential energy than Position C

The statement "Position C has a greater potential energy than Position A" would be false under the assumption that C is at a lower height than A.

So, the accurate descriptions of stored potential energy based on its positions are:

• Position A has a greater potential energy than Position C
• Position B has a greater potential energy than Position A
• Position B has a greater potential energy than Position C
