Re: Question about light and heat



In addition to defining "wor", whatever that is, HRW define "WORK"

Wor is similarly defined as energy transferred.... due to mechanical motion.

HUH?
I am looking in Halliday, Resineck and Walker and it says that heat is transferred internal energy. Is this not saying heat is energy?
