The gravitational force between two objects is proportional to the product of the masses of the objects.

According to the Newton’s law of gravitation, the gravitational force between any two objects held in gravity has their masses product be directly proportional.

directly

Explanation:

The laws of gravitation is given by Newton, which says that the product of masses of the two object held in gravity is directly proportional to the gravitational force. It is also in inverse proportion to the distances among the two objects.

Therefore, when the masses of the bodies increase, the gravitational forces are increased too, but when the distance is increased, the gravitational force decreases.
