can the energy originally stored in gasoline be traced to rotating wheels?
I didn't understand this question when you posted it yesterday. I still don't understand it. The energy in gasoline originally comes from the energy of the decaying trees, vegetation, etc,from which we get oil and coal, from which gasoline is separated, cracked, and/or manufactured. I don't understand where wheels enters the picture unless the caveman's first carts had non-metal wheels and some of them decayed. I am not trying to be funny. If you can explain I might do better than this.
