These calculators can be used to generate data using mass, radius and force.

Calculate the force given two masses and a radius.

F = GMm/r2

Calculate the first mass given the second mass, force and radius.

M = Fr2/Gm

Calculate the second mass given the first mass, force and radius.

m = Fr2/GM

Calculate the radius given the masses and force.

r = √[GMm/F]
