I am not up on flywheel engineering and the mathematics for all the

ramifications are very complex (and I am not sure that the figure of 10

times higher is accurate, because it changes with the distribution of the

weight), but note the following:

1.  The center of the wheel has to accelerate linearly the same as the rest

of the car.

2.  The upper rim has to accelerate linearly twice as fast as the car, and

the lower rim has to decelerate back to 0 (weird, huh).

3.  The wheel (and more so the tire) acts as a flywheel and has to

accelerate rotationally.

4.  Acceleration is a function of the square of the change of velocity.
