Text: University Physics, Young&Freedman. 12^{th} Edition. Chapters 1732.
¥ iClicker keypad and Mastering Physics online homework system (MP) are essentially required. MP comes free with new texts purchased in the bookstore. If you bought a used text or obtained your text elsewhere you will have to purchase MP (details below).
¥ The problem session (Physics 168) should be helpful but is not required. The laboratory (Physics 161 L) is very relevant to the course and is recommended but is not required.

Grading: Not curved. Fractional weighting:
Homework 25%* (written HW 5%, online 20%) Late HW 1/3 off/day ! HW due EVERY CLASS !
Final Exam 25%, Midterm Exams (3) 14%, iClickers 8% (half credit for wrong answers!)
Lowest A = 80%, Lowest B = 70%, Lowest C = 60%.
It is mathematically impossible to get an A in this course without doing the homework.
It is in practice impossible to get a B in this course without doing the homework.
* Students who score in the top 20% on a midterm may choose to substitute very difficult (but interesting) written problems for online homework. Ask me for appropriate assignments if this applies to you.
Exams:
All are closed book, closed notes. An equation sheet will be provided. You will need a calculator.
We will use 10answer scantron sheets. Some questions will be multiple choice; for others, I will ask you to give your answer to 1 significant figure in scientific notation. (This strongly discourages guessing.) Some practice exams from last year are posted at the bottom of this page.
EXAM 1 (Chapters 1720, Thermodynamics) Fri Sept 16
EXAM 2 (Chapters 2124, Electric Fields, Potential, & Dielectrics) Wed Oct 19
EXAM 3 (Chapters 2528, Circuits & Magnetic Fields & Forces) Fri Nov 18
FINAL EXAM (Chapters 17 31, Emphasis on Induction) Fri Dec 16, 7:309:30 am. (Ugh!)
Some examples of how to use the 10answer scantron for numerical answers:
Numerical results require two scantron "answers"
All answers should be given to ONE significant figure only, in scientific notation.
Round to the nearest digit.
Example 1&2. The calculated result was 32.
This is 3.2 x 10^{1}, which rounds to 3 x 10^{1},
so A1 is 3 and A2 is 1.
Example 3&4. The calculated result was 474.
This is 4.74 x 10^{2}, which rounds to 5 x 10^{2},
so A3 is 5 and A4 is 2.
Example 5&6. The calculated result was 0.62334 x 10^{8}.
This rounds to 6 x 10^{7}, so A5 is 6 and A6 is 7.
Example 7&8. For zero, fill in both answers as zero.
(The scantron computer cannot figure out that, for example, 0 x 10^{4} = 0.)
Help!
This should go without saying:
Do not cheat. Any form of cheating behavior will be dealt with severely. I use the words cheating behavior because if you are looking in the direction of your neighbor's paper I can't read your mind and determine whether you are cheating. But I can tell what you are looking at. Do not wear a baseball hat or any other type hat that covers your eyes during a test. All cell phones and other electronic devices must be turned off and placed out of sight. If I even see a cell phone during a test the owner will receive a zero. I will not tolerate this or other cheating behavior, period. And there are many other examples. Use common sense about this. Turn cell phones off and put them away.
Dropping the class. If you drop the course then please let me know so I can give you a WP if appropriate. Otherwise, default is WF.
IClickers (Keypads): The IClickers/keypads we are using this semester can be purchased from the bookstore. You must register your keypad before class on Friday and bring it to class every day. To register your iclicker go to: http://www.iclicker.com/registration/ following the directions provided using your BANNER ID as your "Student ID". You can also go to http://physics.unm.edu/Courses/StudentHelp/index.html for instructions and help on registering. When you register your keypad be sure to provide your name (even though the registration Website treats your name as an optional field).
Mastering Physics (MP) is the online homework system. Your new book comes with an MP package (no extra cost to you). If you have a used book you need to buy the Mastering Physics package from the bookstore or you can go on line with a credit card and buy it. To buy MP access online, go to www.masteringphysics.com then click on the title of your textbook. Then click Buy Now and follow instructions. Whether your MP package came with the text or whether you bought access from the bookstore or online, everyone must register on line and complete the first MP assignment and start becoming familiar with MP before class on Wednesday, Aug. 26.
Important notes for registering: The UNM Zip code is 87131. Our Course ID is PHYC161THOMAS. Your Student ID will be your BANNER ID . Student Access Code: This is a six"word" printed code supplied beneath the pulltab inside your Mastering Physics Student Access Kit. It is valid for registering one student. If the tab in this kit has been pulled back, the code may no longer be valid. If you buy a secondhand textbook, any code supplied with it is probably not valid. In either case, you can purchase a Student Access Code online using a credit card or you can go to the bookstore and buy a mastering physics package. If you need help then click on the ? icon. There are more detailed Mastering Physics registration instructions at http://physics.unm.edu/Courses/StudentHelp/index.html. Listed here are links where other important aspects of the course are described. Please go to these links and read their contents.
For problems with MP, you can go to http://247.pearsoned.com.
