Fair enough, where to? Ground reaction is still reaction -- being a buttress instead of a piston.

Yikes. I don't go for bone compression. Is this not, again, language of simple inertial reaction? Or elastic deformation -- i.e spring-force resistance ?

It does not 'feel' the same as resistance, because of the network. It's a subjective thing - best I can do bro.
The first thing I learned about 3-D mechanics is that it is a counterintuive, and frequently nonlinear environment. Try force paths in spaceframe analysis for statics. Or masonry vaults. God loves vaults. He had medieval stonemasons curse generations of engineers by building lots and lots of them. For dynamics -- I can put you in an airplane and make you "feel" perfectly "right-side-up" but that does not make it so.

God won't help you there -- friction is wholly the work of the Devil -- ruined a bunch of perfectly good perpetual motion machines ...
