[ QUOTE ] Friction keeps your feet from moving on the board but that energy is transferred down to the wheels and, since perfect bearings, the board moves backward. [/ QUOTE ] Exactly. Think about having 2 blocks, one velcro'd on top of the other, sitting on a sheet of ice. If you push the top block, the whole system slides. [/ QUOTE ] Ha.
