Gravitational Constant

(indicates how much pull between two masses)

The Gravitational Constant is an indication of how much Gravitational force exists between two objects, based on their masses. 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
