April 10 classes

Periods 3-4, 8-9:
Please watch either alone or with a partner a Mechanical Universe video on angular momentum. You can start at the 11:00 minute mark and end at the 23:10 minute mark, where they get to the part we are interested in. Take notes as they get into the more detailed definition of angular momentum, and show some examples of conservation. Think about the how and why of a figure skater who is spinning, and how she is able to control the angular speed of the spin. A second video to then check out is on how to set up and problem solve with angular momentum. Same deal, take some notes on the setups so it helps you with some practice problems.

Practice problems are Ch. 10 #40,41,42,43 (on p. 3 of the packet). You can also talk through any issues on the last quizzam in your work groups. Check out the bug problem solution...does it make sense???


Period 5: 
Please watch either alone or with a partner a Mechanical Universe video on electric circuits. This will give some additional visual examples of what a circuit is and how it works, using the rules we have seen in the lab and in class. Please watch from the 3:20 mark to the 20:10 mark. Take good notes, since we will have a brief note quiz tomorrow on what you are watching.

After checking out the video, you can get a couple partners and get a start on the conceptual questions about series and parallel circuits on the page we got Monday. Work through the circled questions on the first page. We will discuss these Thursday, and try to wrap up the basic circuit ideas so we can move into a consequence of electric currents, which is MAGNETISM! Magnetism is also pretty cool, while being a bit mysterious.
