Question
What is the value of the gravitational potential energy when the height of the object is
4 m
- 5 J
- 7 J
- 7.5 J
- 9 J
Hint:
When the height of the object is 4m, the gravitational potential energy is 7.5 J.
The correct answer is: 7.5 J
- The height of the object is directly proportional to the gravitational potential energy.
- When the height is 4m, the GPE is the point where the straight line of the graph meets.
- The GPE is 7.5 J when the height is 4m.
