I was wondering if anyone might be able to offer an account of how a ball screw mechanism works, with a particular quality in mind. Is it actually possible to push the load with the ball mechanism along the screw? I think what I'm describing is happening in this video:

If I have that right, then despite the much greater efficiency of the ball screw, doesn't this present a problem compared to a lead screw? What I mean is, won't the inertia of the load cause it to coast a little way after stopping, since the ball screw's providing little resistance? I don't know why, but I think I had always presumed that a ball screw worked the same way as a lead screw, my thinking being that the lead screw wouldn't allow the load to be pushed along the screw's length. But I guess I had that wrong?
Any anecdotes greatly appreciated!
