What does Newton's law of gravitation state?.
- A.Every point mass attracts every other point mass with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
- B.The gravitational force between two masses is constant regardless of distance.
- C.Gravitational force only acts on objects with mass greater than 1 kg.
- D.The gravitational force is only significant at very large distances.
Model answer
What a good answer should say
- Every point mass attracts every other point mass with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Explanation
Why this works
This statement accurately reflects Newton's law of gravitation, which describes the gravitational attraction between two masses based on their masses and the distance separating them.
