Re: Energy as ability to do work



I certainly bring up the 'tired old' definition as the ability to do
work for the simple reason that most students have heard it. I pays
to draw on their previous exposure even IF that exposure was not
completely rigorous.

I go on to say that the definition is NOT totally correct (at LEAST)
because zero point energy can not be transformed into more useful
energy.

I prefer to define WORK (in a general sense) as the PROCESS of
transforming energy from one form into another.

I hope that my feeble efforts here at the high school level will not
do irreparable harm to very many of the students who are subjected to
my less-than-perfect presentations..

A definition does not have to be perfect to be useful. You can say, in
an elementary school, that "flowers and animals are living things" and
then proceed with "what do they have in common?", etc. Yes, there
are microorganisms, and dead flowers, etc. But this is for later.
