For Monday: LABOR DAY HOLIDAY
For Tuesday: 16: Q-1, 2, 3, 4,6; summary of scotch tape static as assigned in class; Getting to know the static charge physlets, see below. (your HW for Tuesday is to open the 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 this for about 5 minutes.
http://www.compadre.org/Physlets/electromagnetism/ this is another useful page, look at the "electric field" list and open "Field-Line Representation of Vector Fields". This one will require you use IE or Firefox. Move the charges around. Toggle between vectors and lines. In Config B, can you tell which charges are + and - ?
(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.)
HW due Wed: 16: Q-7,8 P-1,2,3, 5, 7, 9 Another good link for static charges that you can run on IE or Firefox: http://vnatsci.ltu.edu/s_schneider/physlets/main/efield.shtml. try the various charge configurations, and press play to see the little charge move.
HW Friday: 16: Q-9, 10, 11; P-13, 15
HW due next Monday: 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
