Spinning Ice Skater Question

Message
[QUOTE="xXhumans0monstersXx, post: 5454574, member: 591062"] So basically, I was doing my AP Physics 1 homework and came across the spinning ice skater question yet again. The question states, "An ice skater is spinning about a vertical axis with arms fully extended. If the arms are pulled in closer to the body, in which of the following ways are the angular momentum and kinetic energy of the skater affected?" I already know that the kinetic energy increases, but can someone please explain to me why the angular momentum stays constant? I've done my research and I can't seem to find an explanation that I understand. I'm not the brightest when it comes to physics so if anyone could help that would be great! I have my first AP exam next week so a reply ASAP would be most appreciated. :) [/QUOTE]
