Re: Sans Work, part I



Hi Bob,

In a previous message I wrote:
Perhaps your effort would be enhanced if you indicated that you were
starting with Newton's second law for a system (F_net = Ma_cm) and that
the mathematics parallels the math used in integrating Newton's second
law for a particle.

and you (Bob Sciamanda) responded:

This is certainly what I would do if I were offering a PROOF of the MET.
My purpose is only a clear statement of the result.
I think "division of labor (not work)" dictates that the derivation of
MET should come from elswhere (like Annapolis?) :)

The intent of my message was to suggest that instead of just telling your
target audience (introductory mechanics teachers) that the content of your
review is a corollary of Newton's laws, that you mention the pathway from
those laws to your corollary. That way they will be in a better position
to understand its relation to Newton's laws.

(I see no point in me or anyone else deriving the pseudowork-translational
kinetic energy theorem for a phys-l posting. It has appeared here
before.)
