The Kinetic Energy of a Rotating Figure Skater.
Chen, Wei R.; Troelstra, Arne A.
NCSSSMST Journal, v3 n2 p3-5 May 1998
When a rotating figure skater's fully extended arms are pulled back toward the torso, the angular velocity is noticeably increased and the kinetic energy of the skater can also be shown to increase. Discusses the change of the kinetic energy during such a process, and the work necessary for such an increase is derived using a dynamic equilibrium condition. (Author/PVD)
