I know it's a bit late, but I forgot to post this on or around my birthday. This is not a homework question or anything important, just something I've been curious about for a while.
If I have a turntable with some(let's say 20) one kg weights on it, that I spin at a constant speed(not regulated by a machine), what will happen if I can remove a weight without influencing(i.e. putting pressure on) the turntable? Will it speed up because there's less weight, slow down because there's less momentum or continue to spin at the same speed? I know that's probably not enough info, but it is foo, after all.
