How can you determine the gravitational potential energy of an object from a gravitational potential graph?.
- A.By measuring the height of the object.
- B.By calculating the area under the graph.
- C.By finding the slope of the graph.
- D.By identifying the maximum potential point.
Model answer
What a good answer should say
- By calculating the area under the graph.
Explanation
Why this works
The evidence shows that the area under the gravitational potential graph represents the work done or energy transferred when moving an object within the gravitational field. This implies that integrating the area gives the gravitational potential energy.
Therefore, the conclusion is that the area under the graph is essential for determining gravitational potential energy.
