Reply to "Flywheel Mass vs. Acceleration"

Rocky, it takes power to spin up any mass. A lighter mass spins-up faster, that's all. Same as swinging a rope with a plastic cat-toy on the end, or substituting a full-sized car tire on the same rope. One will obviously spin up much faster than the other, and take less (arm) power doing it.
