Question

How is gravity affected by distance?

Answer 1

The fundamental law of gravity says:

`F=G(m_1*m_2)/r^2`,

So we can notice that the force that attracts two bodies each other is directly proportional to their masses and indirectly proportional with the square of the distance.

E.G. If the force between two bodies is `F` at the distance `r`, if we move one of them at the distance `2r`, than the force becomes `F/4`.
