Right! As long as the movement of the weight was perpendicular to the direction of travel you could gain some extra mmph moments. Good Call. Ah, but you would lose some mmph on the upper swings.. too bad so sad
I guess to keep this in perspective...
We have 1 force to do work for us here. And that is gravity. (as long as we dont start whipping the weight around in a circle, and create centrifugal force)
As we all know, you can't get more out than was put in. So, the max is 9.8newtons, for 10cm.
w = f x d (if i remember)
