When a figure skater goes into 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.
Be sure to provide substantive responses to at least two of your classmates. For instance a response referencing some specific point in the post to which you are responding is a substantive response. Another example of a substantive post is one which prompts your classmate to address some missed point of the discussion. As always responses such as, “Good Job,” and “I agree,” are considered non substantive and earn no points
