Which of the following has the greatest effect on the gravitational force between two objects?

Question

A. Gravitational constant

B. Distance between objects

Answer 1

The distance has exponential relationship, while the Gravitational force has straight a linear relationship. Thus the distance has more effect.

Answer 2

Gravitational force is defined by Newton's Law of Universal Gravitation:

where "F" is the gravitational force, "G" is the gravitation constant, "m₁" and "m₂" are the masses of the two objects in question, and "r" is the distance between the objects.

Since "r" is squared, the distance between the objects has the greater effect.
