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.

Tuesday: Ranking Tasks - topic of conservation of Momentum. Not too popular.
Annonced Test - Monday 10/20: Newton's Laws
Optional assignment: Forces in 1D is due this Friday. (it was posted a couple of weeks ago)
Some classes discussed relationship between momentum change and Force*time.
Seating chart change Wednesday: First come, first serve, must change to a new table as well as get new neighbors.
Hand back review W/S. Remember to check your answers here.
Wednesday: Answers to Tuesday's HMWK. Momentum Conservation demonstrations. Practice problems. Discuss Force * Time relationship, and another egg-celent demonstration.
Thursday:
Friday: T/G/T Review Game - competitive game for bonus points.
