Week 6

Rest of the sixth week:  Sections 9.1 (center of mass) and 9.2 (momentum), plus examples from Section 9.3?

We jump to Chapter 9 so that we will have learned about momentum before we encounter this topic in next weeks lab. It also fits better right after Energy.

Thurs 2/16:  Exam 2 is given.

Week 7

Mon 2/20:  Wrap up Section 9.3 examples, if needed, and do 1-D collisions from Section 9.4

Rest of the seventh week:  Section 9.4 (collisions in both 1-D and 2-D) is emphasized with limited discussion (or use) of Sections 9.5 and 9.6. [Momentum is usually the last topic on the Midterm.] Sections 8.1 through 8.4 on gravity will emphasize vector problems and (to a lesser extent) potential energy.

Week 8

Mon 2/27:  Start rotational motion (Section 10.1), making use of differential calculus.

Rest of the eighth week:  Sections 10.2 and 11.2 together (torque defined using the vector cross product); Sections 10.3 and 10.4 (applications) plus start 10.5.

Week 9

Mon 3/6:  Wrap up Section 10.5 (torque and rotation) and introduce angular momentum (11.1 and 11.3).

Tues 3/7:  Midterm exam that covers everything through Section 9.6 but probably nothing from Chapter 8.

Rest of ninth week:  Sections 11.3 and 11.4 (angular momentum) plus Simple Machines (from a 19th century handout) and static equilibrium examples from Sections 12.1, 12.2, and especially 12.3.

Have a safe spring break,
and don't forget everything you have learned so far this semester!

Week 10

Mon 3/20:  More examples from Section 12.3 (beams and ladders).

Rest of the tenth week:  Finish Section 12.3 examples. Start unit 4 material:
Sections 13.1 through 13.3 on oscillations See unit 4 for details.

Week 11

Continue with unit 4, (Sections 13.3 through 13.5 (oscillations) and Sections 14.1 through 14.7 on waves).

Week 12

Mon 4/3:  Continue with unit 4, (Finish waves in Section 14.7 plus the Doppler Effect (Section 14.8)).

Tues 4/4:  Exam 3 covers Sections 8.1 through 12.3 with most of its emphasis on material that was not on the midterm. I will announce in class if it also covers Chapter 13.
