Handed back and went over SHM test.

Started powerpoint on Thermal Physics
Got as far as Molar Heat Capacities.

Showed demos of hands in water, hand on table top and leg, found absolute zero by extrapolating graph of T vs P to zero P.

Collected RA 14.1, 14.2

Forgot to assign homework.

Test on SHM

Students picked up RA 14.1, 14.2 for homework due next time.

Friday, Oct 16, 2009 - 3B

Reviewed for SHM test.

Students reviewed from Tsokos book.

I put up optional quia review on SHM.

Test next Tuesday.

Answered questions on spring constant lab.

Many students were not ready to hand it in so I extended the due date to Friday with no late reports accepted.

Went over the remainder of the problems on the problem sheet.

Spring Constant Lab due Friday.
Test on Tuesday.

Reviewed how slope of velocity vs time graph gives acceleration and how slope of displacement vs time graph gives velocity. Did this for linear motion and then showed how it works for SHM.

Did several examples.
Went over first page of problems from SHM problem sheet.

Showed how to use energy to solve SHM problems.

Wed, Oct 7, 2009

Lectured on SHM.
Showed analogy between uniform circular motion and SHM with turntable and pendulum.
Showed the "zap" relationship to get frequency and period and derived equations of SHM.

Gave students last half hour of class to finish up spring constant lab.
