HMWK due Tuesday: Read p. 104-117, p.111#2-8, 117#1-6

Monday: Finish notes/Discussion on Momentum Conservation. Demonstrations: Free fall with and without air resistance (vacuum tube), center of gravity, moment of inertia (rotational inertia)

Rotational Inertia = spinning objects have momentum too, and an object with mass farther from its center has more momentum, and requires more force to accelerate to the same (spinning) speed.

Ice skater trick; conservation of angular momentum of spinning object.
