Physics 1120, General Physics 2: Electricity, Magnetism, and Optics
Instructors: Steven Pollock and Victor Gurarie
Electrostatic forces drive this microscopic comb actuator from Sandia National Labs. They have
movies showing it connected to all sorts of micro-mechanical gizmos.
Week 3 Highlights: Gauss' Law
There are always 3 different things you need to turn in each week. See "assignments" link on the left.
1) CAPA homework (online, due Friday night - technically, by 8 AM Sat morning)
2) Tutorial homework (submitted hard copy, at the START of your recitation on Tuesday) and
pretests (online, due Mon night - technically, by 8 AM Tuesday morning)
All are on a regular schedule, every week!
Don't forget about # 3, you need to do the pretest over the weekend (or on Monday)!
Reading: Ch 27 on Gauss' law
- Exam Review will take place in G125 on Mon, 6:00PM-7:00PM. Nothing planned or formal, just an extra office hour, basically, for you to ask questions if you want.
- Midterm #1 is Tuesday Sept. 18, 7:309:15 pm.
See exam page for more information soon.
- "Virtual office hours" is where I post
email questions, if I think they're of general interest.
- We also have an 1120 CULearn page . We'll post your grades there later this term. There is also a "threaded messages" list - you are welcome to ask each other questions about the course, even the homework there, and respond to one another. I will be monitoring this occasionally, so please use good judgement and common sense. If anyone uses this to copy answers, tell formulas, or otherwise sabotage the learning goals of the course, we'll just turn it off. But I think it's great for you to ask questions, discuss the problems, give hints, talk about where you went to get help or how you figured something out, and so on. Use it as a resource to collaborate (but not to cheat!) When in doubt about how far you can go in "giving help" to other students' questions: if you feel comfortable knowing that I'll be reading it, then it's probably fine!
- The "Many
useful links" (near the bottom) contains relevant Java applets.
(Also a video of the grape in a
microwave) Check it out.
