Re: HISTORY (was: ENERGY BEFORE Q)

If we identify KE with "vis viva" (m*v^2) then potential energy
would have to be 0.5*m*g*h. Otherwise KE+PEgrv would not
remain constant. Right?
Ludwik Kowalski

Ludwik, the concept of PE came after the W/E principle so by the time of
PE, KE was 0.5mv^2.

Now someone will now pontificate re this comment. but ithe pontification
will likely be somewhat extraneous -- as usual.
