Figure Skating and Angular Momentum

[parwana]

In Figure Skating, when the players are rotating, there’s a way to slow him/herself down, do you know what’s that? Using the knowledge of angular momentum, analyze qualitatively why he/she can achieve such effect?

Key words: hand spreading, moment of inertia, conservation of angular momentum.
