Dear Jerry:  You are an in-the-mold DUNCE who thinks that UNITS must
be reflected in every operation of equations.  Sometimes units are
just proportionality factors, and those do NOT have to be expressed in
the "units" of the result!  For your edification (hopeless, I'm sure):
Force, Momentum, PE, KE and Power all have just one unit—pounds (or
the metric equivalent).  Only Work is correctly written in existing
textbooks as "foot pounds".

I won't be wasting my time replying to you any more, that is, unless
you can show that you have something in your belfry besides feathers
and dung.  — NoEinstein —
