What does the area under a gravitational potential graph represent?.
- A.The total energy of the system.
- B.The work done against gravity.
- C.The gravitational force acting on the object.
- D.The change in kinetic energy.
Model answer
What a good answer should say
- The work done against gravity.
Explanation
Why this works
The evidence shows that the area under the curve in a gravitational potential graph corresponds to the work done when moving an object within the gravitational field. This implies that calculating this area provides insight into the energy required to move the object.
Therefore, the conclusion is that the area represents the work done against gravitational forces.
