Deletion of Terminal velocity (derivations)

Comment: Please see . This is clearly a sub-article meant to save space. I would advice the editors to move as much derivation information into this article, and leave the main one for the words. Would make everything better for everyone: a non-math inclined reader would get a nice explanation, and math inclined readers can go to the derived (ha-ha!) page. Thanks
