k{g^{- 2}}\). Overall this equation is simpler than it looks as long as you ensure that: distance is given between centres units are all in metres and kilograms The force of gravity exists between ...

The force of gravity is different on different planets ... The gravitational field strength (\(g\)) of a planet is the weight per unit mass of an object on that planet. It has the units, newtons ...
