(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
- 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.
