How can you interpret a horizontal line on a gravitational field strength graph?.
- 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 constant
Explanation
Why this works
The evidence shows that a horizontal line indicates no change in gravitational field strength over a distance. This implies that the gravitational field strength remains the same, leading to the conclusion that it is constant in that region.
