For Monday: 16: Q-1, 2, 3, 4,6; summary of scotch tape static; getting to know the static charge physlets, see below. (your HW for Monday is to open each site and make sure you can run the physlets and show me a printout (not hand-drawn) of each of them.)
http://phet.colorado.edu/en/simulations/category/physics is the site where you can find most of the physlets we'll use in class. You can select "electricity, magnets, and circuits" to get a shorter list. We'll look at "electric field of Dreams" and "electric hockey" first. Play with these each for about 5 minutes.
http://webphysics.davidson.edu/physlet_resources/bu_semester2/index.html. this is another useful page, look at the "electric field" list and open "field lines and field vectors". This one will require you use IE or Firefox.
Another good link for static charges.http://vnatsci.ltu.edu/s_schneider/physlets/main/efield.shtml.
(IMPORTANT NOTE: MANY TIMES, IF AN APP OR PHYSLET DOESN'T RUN ON A COMPUTER, IT IS PROBABLY THE FAULT OF THE WEB BROWSER YOU ARE USING. SO IF CHROME DOESN'T WORK, TRY INTERNET EXPLORER. IT IS YOUR RESPONSIBILITY TO FIGURE OUT HOW TO WORK THESE PROGRAMS.)
Tuesday: lab experiment on air flow over an object in the faraday cage. look at negative charge (?) and positive charge (balloon)
HW due Wed: 16: Q-7,8 P-1,2,3, 5, 7, 9
NOTE DELAY: HW due Friday: (draft of) the memo report on static charge loss. Please see example file at top for a rough outline of such a report. You need to provide more details of course than I did, but it should all fit on one page (typed, single space, with figure and table)
HW Friday: 16: Q-9, 10, 11; P-13, 15
HW due next tuesday: read 16.7, 16.8; do 16: Q-13,14,15; P-23,25,27,29,33
quiz next Tuesday : on Coulomb's Law and forces
- Describe when induction will occur and its effects (on conductors and insulators)
- Describe conduction and induction cases for electroscope practicum
- Be able to do simple coulomb’s law calculations
- Be able to apply vector math to do 2-D coulomb’s law problems
- Know that Coulomb’s law is complete for electrostatics, not complete for electrodynamics
