Exam-style question
Try this first
In a gravitational potential graph, what does a horizontal line represent, and what does this imply about the gravitational potential energy of an object?.
Model answer
What a good answer should say
- A horizontal line in a gravitational potential graph indicates that the gravitational potential energy remains constant as the object moves.
- This implies that no work is done on the object by the gravitational field in that region.
Explanation
Why this works
This answer effectively identifies the significance of a horizontal line in the context of gravitational potential energy, demonstrating an understanding of the implications of the graph's shape. It tests the ability to interpret graphical data related to gravitational fields.
