Homework Statement
Where does mass get the force of gravity?
Homework Equations
F = G(m1 x m2)/r^2
F = force (N)
G = Gravitational constant (Nm^2/kg^2)
m = mass
r = distance between m1 and m2
The first who carried out experiments that led to an empirical determination of G was Cavendish. By means of torsion springs, I think.how is the gravitational constant derived?
