In my high school physics class Mr. Gianetti put some ball bearings into a tube, and called me to the front to turn the tube over and over a number of times. He measured the temperature of the ball bearings before and after I did this, noted the temperature difference, and said I had used 300 calories doing so. "There goes breakfast," I said. At that point he discussed the difference between calories and kilocalories, the latter usually just called "calories" in diet books.
