Ok. I see! Thank you. I guess I have more studying to do.BvU said:G is not the magnitude of gravity. It is the magnitude of the gravitational force.

##G_k## is the gravitational constant. It is NOT the equivalent of ##a## in ##F = ma##.

The dimension of ##G_k## is length^{3}x mass^{-2}x time^{-2}, units Nm^{2}/kg^{2}.

The dimension of 'a' is length x time^{-2}, units m/s^{2}.

And 'm' is a mass, in kilogram, NOT the product of two masses divide by the square of their distance: the latter has a dimension kg^{2}/m^{2}, which is incomparable.
