"It would be great fun to have a car that actually resisted the pulling forces based upon its supposed weight, and that likewise would demonstrate momentum once rolling." ***************************************************************** Response;
I believe John Allen did that "way-back-when", when he built a boxcar with a flywheel in it attached to the wheels for just such a momentum effect. I guess he was trying to capture the scale-weight affect. He must have been thinking about it too.
