Question
Which object has more gravitational potential energy when both have the same mass?
- 2m
- 3m
- Both
- None
Hint:
The gravitational potential energy increases as the height of the object increase.
The correct answer is: 3m
- The gravitational potential energy is directly proportional to the height of the object.
- The increase in height of the object increases the GPE.
- The object that has 3 m in height has more GPE compared to the object that has 2 m in height.
