gravitational constant

(indicates how much pull between two masses)

The gravitational constant is an experimentally-determined value that relates gravitational force between any two objects to their masses and the distance between them. The force is proportional to the product of the masses and inversely proportional to the square of the distance between them, and the gravitational constant relates the masses and distances to the magnitude of the force.

F = -Gm1m2/r²

The gravitational constant is 6.674 × 10-11 N·kg-2m2, where
