PRESENT:  "ENERGY IS THE CAPACITY TO DO WORK."

ACTUALLY, WORK IS THE SCATTERING (DISSIPATION) OF ENERGY.

THE PRESENT DEFINITION STATES THAT "ENERGY IS THE CAPACITY TO DO SCATTERING OF ENERGY."

ENERGY CAN BE SCATTERED, YIELDING WORK.  BUT THE CAPACITY TO PERFORM THAT SCATTERING IS NOT ENERGY!  (E.G., IT MAY BE RESISTANCE.)

COMPARE TO:  "A FISHHOOK IS THE CAPACITY TO CATCH FISH."

ACTUALLY, A FISHHOOK IS A BENT WIRE WITH A  BARB.  IT HAS THE CAPACITY TO CATCH FISH (GIVEN OTHER CONDITIONS).  BUT THE CAPACITY TO CATCH FISH IS NOT WHAT IT IS.
