Disney's movie "Ice Princess" mistake??? so I watched the movie over the summer... here's word for word out of the script "Now, l'm going to increase the centripetal force by tucking in my arms. This will increase my moment of inertia, so l will spin...faster." so it's been bugging the hell out of me......if she pulled her arms in, wouldn't that decrease her moment of inertia to make her spin faster...to conserve angular momentum? thanks.
