Answer:
The gravitational force between two objects is proportional to the product of the masses of the two objects.
The gravitational force between two objects is inversely proportional to the square of the distance between the two objects
Explanation:
Newton proposed the universal law of gravitation. It is universal because it applies to everything in this universe. Any two objects that are separated by some distance will experience the gravitational force. It is the weakest force and is always attractive. It is never repulsive.
This force will change if the masses that interact are changed or if the distance between the interacting masses changes. The mathematical relation is F = G M₁ M₂÷ d², for any two objects of mass M₁ and M₂ , that are separated by a distance d.
