Course Description

Welcome to Physics 3! The textbook is H. D. Young and R. A. Freedman, University Physics, 11th Edition (Addison-Wesley, 2004). You should already be familiar with Chapters 1-14 and 17-20 from Physics 1 and 2. We will cover Chapters 15-16 and 21-26 in our study of mechanical waves, wave interference and normal modes, sound and hearing, electric charge and electric field, Gauss's law, electric potential, capacitance and dielectrics, current, resistance, electromotive force, and DC circuits.

The prerequisites are Physics 2 or 22, and Mathematics 3A-B-C.

The recommended preparation is Mathematics 5A (may be taken concurrently) and Physics 3L (may be taken concurrently).

Discussion Sections

There are not as many discussion sections as there were for Physics 1 and 2. The discussion sections meet in the same lab rooms where the Lab Section (Physics 3L) meets. If you are not taking the lab, you are welcome to attend any discussion section. Discussion sections are scheduled for the following weeks:

Week of	Lab room
Sept. 27	Broida 2316
Oct. 11	Broida 2302
Oct. 18	Broida 2316
Nov. 8	Broida 2302
Nov. 15	Broida 2316
Nov. 22	Broida 2302

Laboratory Sections

If you are taking the lab, you must register separately for Physics 3L. Buy the Physics 3 Lab Manual in the Bookstore. Some of the labs are out of sequence with the lecture, so read the lab manual before coming to the lab. Your lab grade for Physics 3L will be determined by your TA.

Homework

Homework assignments will be submitted online using MasteringPhysics. If you don't own a computer, you can use the computers in the Davidson Library, or during drop-in hours at the Instructional Computing (IC) labs on campus. See the lecture schedule below for due dates. Homework problems will be the same as those in the text, but with different numerical values. Homework solutions will be available electronically through ERES (http://eres.library.ucsb.edu/).

If you have used MasteringPhysics before, you do not have to pay any new fees, simply use your previous username and password.
The Course ID to use for this course when registering on MasteringPhysics is MPCAMPAGNARI0004.

If you have not used MasteringPhysics before, then you should have received a Student Access Kit for MasteringPhysics with your purchase of a new textbook from the UCSB bookstore. The Kit contains instructions and a code for you to access MasteringPhysics. If you did not purchase a new textbook, you may purchase an online subscription with a major credit card by going to http://www.masteringphysics.com and following the links to purchasing online.

Please note the following when submitting homework on MasteringPhysics:

There is an important difference bewteen the "submit" button and the "submit problem" button.
You must use the "submit" button for each part of a problem (you only have an unlimited number of attempts per answer when you use the "submit" button.)
If you have answered all parts of a problem correctly, the problem is automatically scored.
If you have NOT answered all parts of a problem correctly, you must use the "submit problem" button BEFORE the due date, otherwise no parts of the problem will be scored.
If you use the "show answer" button, the score will be zero and you won't be able to make any more attempts.
For multiple choice questions there is a penalty for guessing wrong. If N is the number of options to choose from, then a fraction 1/(N-1) of the total points for the problem are deducted for each unique wrong answer submitted.

Exams

Calculators are allowed. Notes will also be allowed (details on this later). The best way to prepare for the exams is to practice solving problems! In addition to the homework, try doing some of the other problems in the textbook. Answers to odd-numbered problems are in the back of the book.

Grading

Your total point score will be determined as shown below. A curve will be used to assign letter grades at the end of the course.

Online Homework	15%
Midterm	35%
Final	50%

Where to Get Help

Talk to your instructor.
See your TA at lab or discussion section.
Physics Study Center (PSC), Broida 3314. This is where all TAs hold office hours. The PSC is open Monday to Friday, 8:00-4:30, and TAs are on duty at most times. Note that ANY TA in the PSC is able to provide assistance with this course, not just the TAs for Physics 3. To find when any TA has office hours, you can check the Schedule of TA office hours in the PSC.
Campus Learning Assistance Services (http://www.clas.ucsb.edu/) offers drop-in hours and free tutoring.

Where NOT to Get Help

Academic dishonesty is never acceptable. Cheating hurts everyone, whether while taking exams or working homework. You are welcome to work with other classmates on homework, but ultimately all work you turn in should be your own. Plagiarism will receive no credit! If you can't do the homework problems by yourself, then you won't be able to do the exams! The method you use to get the answer is as important as the answer itself.
