Re: pseudowork

A motionless box of mass m is dropped from an infinitesimal
(ignorable) height onto a rapidly moving conveyor belt.

Let the 'system' be the box.

Let's use some of these 'confusing' terms to describe the gain in KE
that the box undergoes.

(or is this a non-issue?)

I agree wholeheartedly with Jim G. that this term is
less than worthless. If we focus on energy transfers
in/out of a system and allow for energy to be
"dissipated" within a system (which means simply that
such "dissipated" energy is no longer readily
accessible) by, for example, frictional processes, one
entirely avoids the fiction of "work done by friction"
- pseudo or otherwise. John Barrere
