What does a downward slope on a gravitational field strength graph suggest?.
- A.Gravitational field strength is increasing
- B.Gravitational field strength is decreasing
- C.Gravitational field strength is constant
- D.Gravitational field strength is zero
Model answer
What a good answer should say
- Gravitational field strength is decreasing
Explanation
Why this works
The evidence shows that a downward slope indicates a reduction in gravitational field strength as distance increases. This implies that the gravitational force is weakening, leading to the conclusion that the gravitational field strength is decreasing.
