If you want to be an Olympic athlete, don't slack off during Physics class. In which of these Olympic sports is rotational - or angular - momentum NOT a key component to success?

Angular momentum is the increase in speed when body position is changed. A good example of angular momentum in action is when figure skaters start a spin by pulling in her arms to lessen the Moment of Inertia. By the Conservation of Momentum Principles, the angular speed must then increase.
