You can bet, if that were the case, they would fit 9 or 10 and call them Super Duper Fast or somesuch! |
My days of physics are long behind me, but I seam to recall then when it came to moving bodies there were two considerations: inertia and momentum.
I am with you entirely regarding weight on a string which will add inertia which will need to be overcome. But just a thought, the weights are positioned very close to the cams, which is a different proposition to a weight in the centre of the string. The cam is attempting to reel the string into the cam, which in turn is causing the string to shorten and propelling the arrow forward. The weights will initially create inertia, but once they start moving they will have momentum which will assist in their movement like a flywheel does. Maybe and it is only a maybe, this momentum speeds up the reeling of the string into the cam????
