Question: An ice skater spins about a vertical axis through her body with her arms held out. As she draws her arms in, her angular velocity increases. You know this to be the case because:

1) angular momentum is conserved.

2) kinetic energy is conserved.

3) torque is conserved.

4) moment of inertia is conserved.
