If so, why do people use the word "energetics"?
Where did you see the term "energetics" used?
The Wikipedia article on "energetics" states it as a sort of generalization of thermodynamics. However, it is in big need for further contributions and doesn't look very reliable. It doesn't even exist in my language.
Yes, I saw that and dismissed it as junk. "Energetics" might be an old-fashioned term. I've not seen it in any textbook I've used.
It might as well be a very modern term: Googling it gave me a lot of sports wear and related stuff! But Google is country sensitive ...
The word "bio-energetics" is used by Nick Lane in his book, "The Vital Question: Why Is Life The Way It Is?", that Bill Gates is reading or has read.
I think it's because "bio-energetics" doesn't involve heat a lot, which "thermodynamics" seems to imply is the most important form of energy?
