The masses of the objects and the distance between them determines the force of gravity between them. The more massive and closer together they are, the greater the force of gravity.
Two things reduce the force of gravity between two objects: an increase in the distance between the two objects or decrease in mass of the two objects
The mass of the objects and the distance between them.
Gravity is an attractive forces between any 2 objects. The strength of the attraction is proportional to the mass of the two objects and is inversely proportional to the square of the distance between the objects. That is to say that gravity is stronger between larger objects and gets weaker as the 2 objects get farther apart.
The pull of gravity is affected by the amount of mass, and by the distance.
Mass and distance between the COG of the 2 masses
-- the product of their weights -- the distance between their centers
Mass and volume.
The masses (both of them), and the distance.
weight and mass
The masses (both of them), and the distance.
The magnitude of the gravitational force between two objects depends on-- The product of their two masses-- The distance between their centers of mass
The masses of the objects involved and the distance between them (technically, the distance between their centers of mass).
