Multiple Choice

FIGURE 11-2
-A figure skater is spinning slowly with arms outstretched. She brings her arms in close to her body and her angular speed increases dramatically. The speed increase is a demonstration of

• A) conservation of energy: her moment of inertia is decreased, and so her angular speed must increase to conserve energy.
• B) conservation of angular momentum: her moment of inertia is decreased, and so her angular speed must increase to conserve angular momentum.
• C) Newton's second law for rotational motion: she exerts a torque and so her angular speed increases.
• D) This has nothing to do with mechanics, it is simply a result of her natural ability to perform.
