Re: energy introduced without work


I don't think it is wise to "define" energy in terms of work. Energy
is the primary and fundamental quantity. Work is a secondary and
derived quantity. Work should be defined in terms of energy, not the
other way around.

The concept of "energy" is an _invention_ (by Young) as is the concept of
"work".

How can either be considered "fundamental" and the other not?
