Week 3

Newton's Laws (Sections 4.1 thru 4.4); Sections 4.5 and 4.6; problem solving from Section 5.1.

Thurs 1/26:  Exam 1 given.

Week 4

Sections 5.1 and 5.2 (two days of examples); circular motion (Section 5.3) and friction (Section 5.4); start work and energy (Section 6.1).

Week 5

Mon 2/6:  Section 6.2.
This lecture usually includes a conceptual overview of integral calculus, defining the work integral as the area under the graph of the force as a function of position. The main example, which applies to our central problem of finding the work done by a spring, also makes it clear (because the example is one also used at about this point in Calc I to show the meaning of the derivative) that the integral is the anti-derivative.

Rest of week 5 Sections 6.3 and 6.4; Energy conservation in Sections 7.1, 7.2, and 7.3.

Week 6

Mon 2/13:  Section 7.3 (examples), the last material on Exam 2.

Rest of the sixth week: Start unit 3, (Sections 9.1 thru 9.2 on momentum and examples from Section 9.3).

Thurs 2/16:  Exam 2, Sections 4.1 to 7.3 covered by HW-06 thru HW-11.
