Seniors, Sept. 11 work

Unfortunately, I had to leave with illness; very sorry about this. Happy hump-day!

Please be sure to talk with others to go through the practice problems from last night on electric potential and the use of energy, and have consensus on those.

For today, check out a video on an electrical analog to projectile motion, where we imagine an electron moving into a constant, uniform electric field. This electric force will play the role of gravity for a ball rolling off a table. Take notes on it, along with writing down any questions that come up.

Also, to begin getting a sense of scale for electricity, check out two short introductory videos on the power grid. Click here and then for this second one. Again, take notes and make any comments or questions so we can chat about them.

After the videos, make good use of time to work through practice problems:
        AP Problem from 2000, from the Substitute Teacher;
        Ch. 21 #33, 92     these are in the initial unit packet
        Ch. 23 #4, 11, 13  these are in the small potential pack from yesterday

For SAT II people, we'll meet Thursday during periods 5, 6.
