(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
- F - the force.
- G - the gravitational constant.
- m1 and m2 - mass of the two objects.
- r - distance between the two objects.
The gravitational constant is
6.674 × 10-11 N·kg-2m2,
- N - Newtons (force).
- kg - kilograms.
- m - meters.
