The gravitational attraction between two objects depends on both their masses and the distance between them. It is proportional to the product of the masses of the two objects divided by the distance between them (mass1 x mass2)/ distance between.
-- the product of their two masses -- the distance between their centers
The product of the masses of the two objects, and the distance between them.
The forces that arise on account of gravity depend on the masses of the objects being attracted toward each other, and on the distance between their centers.
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 strength of gravity depends on the value of the universal gravitational constant.The size of the gravitational forces between two objects depends on the productof their masses, and on the distance between their centers.
The mass of the objects and the distance between them.
-- the product of their two masses -- the distance between their centers
The product of the masses of the two objects, and the distance between them.
The masses (both of them), and the distance.
The masses (both of them), and the distance.
The forces that arise on account of gravity depend on the masses of the objects being attracted toward each other, and on the distance between their centers.
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 forces of gravity between any two objects depend on the mass of theobjects ... stronger for greater mass ... and on the distance between them ...stronger for smaller distance.
The product of their masses and the distance between them. (It doesn't depend on the size of either individual mass, only on the product of the two.)
The strength of gravity depends on the value of the universal gravitational constant.The size of the gravitational forces between two objects depends on the productof their masses, and on the distance between their centers.
We don't know why. But we are convinced, by hundreds of years of experiment, reason, and successful application, that it does.
Thing #1). The product of the masses of the two objects. (You don't have to know the individual masses, only their product.) Thing #2). The distance between the centers of mass of the two objects.
