What is rolling friction? What type of simple machine is a fork? How big is a jet engine? What is the Jet Propulsion Laboratory? What thermodynamic cycle does a jet engine operate on? What is the difference between a turbine and jet engine?
Static electricity also familiarly exists when we rub balloons on our head to make our hair stand up, or when weshuffle on the floorwith fuzzy slippers and shock the family cat (accidentally, of course). In each case, friction from rubbing different types of materials transfers electrons. The...
