Question

The force, F, between two bodies of mass m1 kilograms and m2 kilograms whose
centers of mass are a distance of r meters apart is given by the formula F = (Gm1m2)/ r2
where G is the gravitational constant of the universe. What are the units of the gravitational
constant G?

Answer 1

G=F*r^2/m1m2

= N-m^2/kg^2 and in terms of fundamental units (N=kg-m/s^2) then
G-kg*m^3/(kg^2*s^2)
