Respuesta :

1) directly proportional to mass of the objects

2) inversely proportional to the square of distance between the two objects

Answer:

the objects' masses

the distance between the objects

Explanation:

The force of gravity between any two objects is affected by the masses of the objects and the distance between the objects. The more massive the objects are, the greater the gravitational force between them will be. And the closer together the objects are, the greater the gravitational force between them will be.
