In a gravitational field strength graph, what does the area under the curve represent?.
- A.Work done in moving a mass
- B.Gravitational potential energy
- C.Mass of the object
- D.Gravitational force
Model answer
What a good answer should say
- Work done in moving a mass
Explanation
Why this works
The evidence shows that the area under the curve in a gravitational field strength graph corresponds to the work done against the gravitational field. This implies that it quantifies the energy required to move a mass within that field, leading to the conclusion that it represents work done.
