The mass of the objects and the distance between them.
|
|
|
The weight of the objects and the distance between them.
|
Detailed explanation-1: -The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
Detailed explanation-2: -Hence, the two factors are the masses (m1 and m2) of the objects and the distance (R) between the objects.
Detailed explanation-3: -Two factors determine the magnitude of the gravitational force between two objects: (1) their masses and (2) the separation distance between them. The size of the force is proportional to the product of the masses of the two objects.
Detailed explanation-4: -Hence, we can conclude that the gravitational force between two bodies is directly proportional to the product of their masses.
Detailed explanation-5: -Hence, if the distance between the bodies is doubled, the gravitational force of attraction becomes one-fourth.
