This doesn't explain why you get the same amount of curl if the stone rotates twice during its run or twenty times.

- psheets 9y agoThe delta of the ice on stone speed between the sides is not dependent on the rotational speed but liner speed in relation to the rotational speed.

V_cm: velocity of center of mass V_l: velocity at left edge V_r: velocity at right edge R: radius of stone w: angular speed of stone (CCW is +) V_l = V_cm + R*w V_r = V_cm - R*w delta = 2*R*w Even if it was dependent on linear speed / rotational speed, the only way to change # of turns / run is to change linear speed / rotational speed.
