I mean how does your algebra get you there? i.e. the workings.

It is a changing length from the ground where v=0. I give up.

Simply this is the way we where shown to calculate a distance from the ground.
Mr. Scientist, one of the things I don't understand is: why are you using not-precise language and concepts in your lessons on energy while you use highly formal algebra (tensorial calculus) in your lesson on General Relativity? Does it have any sense? If you use the attitude of trying to teach simple, immediate, intuitive physics, then why writing computations with tensors? And if you want to teach formal, precise physics, why so many imprecisions in the other lessons? It's meaningless.

The only explanation I found at the moment is that you are just copying and pasting things from books (or from the net).
