Where does the friction energy go?

Doesn't friction fuck up conservation of energy entirely?

Heat? Yes?

It turns into heat.

No.

energy is conserved in a closed system. accounting for friction, the two blocks do not form a closed system. If however they are contained in an insulated box, this whole system will be approximately closed and the temperature increase from the heat of friction will last.

solids are tightly packed small marbles

Rub your hands together really fast. That burning sensation and the heat in your skin? That's where the friction energy went.

Heat is what moves the electrons around ;)

you're asking the wrong question. the question is more properly "what is the physical mechanism of friction"

Also sound energy is a thing.

My hand moves electrons around when I slap people.
