Gave a second quiz on torques - this time a bar problem.
Asked what student's remembered from the Hewitt video.
Zapped the law of gravitation to derive Kepler's laws. Went over several examples of close is fast.
Did not have time to do Orbit of Mercury so instead, for fun, showed parts of 3rd Rock From the Sun - The Physics of Being Dick. Block 1 liked it. Block 3 not so much so instead I started going over the Kepler's Laws Worksheet.

Answered any remaining questions on the torque worksheets.
Quiz on canoe problem.
Finished Hewitt video on Gravity.
Several students did not complete the Kepler's Laws worksheet so I asked them to finish it for Monday.

Went over problems on Statics and Equilibrium worksheet. Many students did not complete the worksheet so I gave a bit of time in class for students to work on them before continuing to go over the problems.
Started Hewitt video on Gravity. Discussed revolution in thinking caused by the Law of Universal Gravitation.
Showed how the inverse square law results from our world with 3 spacial dimensions.
Handed out Worksheet on Kepler's Laws as homework.

Lectured on torque. Showed demos using spool and had students vote with their feet on outcomes. In Block 3, Tommy stood alone and was correct.
Tried to show demo using Health-o-meters and board.
Solved canoe and bar problems.
Handed out worksheets: Statics and Equilibrium worksheet - students had a bit of time to start this worksheet in class with me available for questions.
Also handed out Supplemental Problems in Statics for homework

Collected Circular Motion Labs
Collected RA 7.4
Asked if any questions on uniform circular motion from yesterday.
Gave quiz on circular motion.
Handed back RA 7.3
Went over any questions on RA 7.3
Handed out problem sheet on uniform circular motion, including 3 problems on reverse side. Gave students time to work on the problem sheet in class.
Extra credit for correct solutions to "Return of the Cone", and/or "Mr. Holmes' Favorite Physics Problem" by Monday.

Collected RA 7.1
Handed back RA 7.1.
Expanded chart showing correspondence between linear motion and rotational motion to include forces and torques. Used this to lead into going over RA 7.1.
Talked about the energy stored in diatomic molecules and monoatomic gases.
Showed demo tossing book into the air. Alan W said you could rank the size of the rotational inertia by the length of the axis that intersected the book - the greater the length, the smaller the rotational inertia. Very astute. Showed that rotation about the middle axis is unstable.
Introductory lecture on Uniform Circular Motion.
Showed that acceleration and centripetal force are directed towards center and thus centripetal. Derived the centripetal force equation. Did examples on calculating period, frequency, linear velocity, centripetal acceleration, centripetal force.
In problem solving strategy, always choose one coordinate axis in the direction of the acceleration. Showed some examples using "zap".
Handed out RA 7.4. Due tomorrow along with Circular Motion Lab.
