When a figure skater goes into a spin, she will begin with her arms extended, and then draws her arms inward. As a result, the ice skater spins faster. Describe why this works in terms of angular momentum. Provide your own example of the conservation of linear momentum in a collision. Use the words elastic, inelastic, and totally inelastic in your explanation.
