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.
