Which of the following correctly describes the relationship between gravitational force and distance?.
- A.Gravitational force increases as distance increases.
- B.Gravitational force decreases as distance decreases.
- C.Gravitational force is constant regardless of distance.
- D.Gravitational force decreases as distance increases.
Model answer
What a good answer should say
- Gravitational force decreases as distance increases.
Explanation
Why this works
The gravitational force between two masses decreases as the distance between them increases, following the inverse-square law. This means that as the distance increases, the gravitational force becomes weaker.
