No, I don't advocate abandoning the concept of work. I always
introduce energy before work, using Feynman's Chapter four as
the first item of business. I read the parable of Dennis and
his blocks to them in it entirety. Work is introduced later as
separate topic. I *never* touch what I consider to be a
damaging definition of energy as "the capacity to do work". I
consider it to be as odious as the definition of entropy as a
measure of the disorder of a system. Both definitions are, so
far as I understand the concepts, simply *wrong*.
The energy is a function of the state of a system.
