Does the force of gravity act between two objects?.

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass

Explanation:

If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces
