Text: Sears & Zemansky’s University Physics with Modern Physics, Vol. 2, UW edition, by Young & Freedman

Mastering Physics for homework: Log on to: www.masteringphysics.com

Go to University of Wyoming and class JTPHYS1220F2013

Laboratory Manual - Physics 1220/1320, by Rudi Michalak, available at university bookstore

Poll Everywhere for interactive in-class activities and attendance: You need to register at http://www.polleverywhere.com. Under settings add your phone number, and then certify it to the United States (not US Educator). In order to make your name visible to the instructor, go to Voter Registration on the left side under settings, register as a voter (at the bottom), and then put in the instructor's email address (see detailed instruction below).

Supplementary Reading Suggestions:

The Feynman Lectures on Physics, and

Physics for Scientists and Engineers with Modern Physics by Serway

Goals: This course is designed to give science and engineering majors instruction in the fundamental principles of heat, electricity and magnetism

Prerequisites:

Grades of C or higher in MATH 2200, 2205 (Calculus I, II) and concurrent enrollment in MATH 2210 (Calculus III)

Topics to be covered:

1. Electric fields, Gauss’s Law and electric potential

2. Current, resistance and dc circuits

3. Capacitance and Dielectrics

4. Magnetic field and its sources

5. Electromagnetic induction

6. Inductance, ac circuits and electromagnetic waves

7. Temperature and heat

8. Thermal properties of matter and ideal gas

9. The first law and second law of thermodynamics

Discussion Sessions

Whereas the lectures will focus more on general concepts, the discussion sessions will provide opportunities to review specific problems and active environment to exchange ideas with your peers. Students will work in groups, and problems will be worked out in class with the assistance of your TA’s. You will also see a lot of practical problems and their solutions with actual numbers. Discussion attendance is mandatory and in your best interest: discussion section problems and questions may be used on exams. Quizzes will be given during discussion sessions.

Labs

Participation in all laboratories is mandatory for the successful completion of this course. If you have to miss a lab, it is your responsibility to contact your lab instructor so that you may attend another lab section the same week or make-up for the missed lab in the make-up lab weeks. There will be two make-up weeks during the semester. In order to pass the course, you have to take part in ALL laboratory sessions. No lab grade will be dropped.

Exams

Homework will contain mostly quantitative problems, whereas lectures will deal with largely conceptual, multiple-choice questions. Hence, the exams will contain both quantitative and conceptual problems. The exams will be closed book and closed notes. I will provide a "cheat sheet" with useful formulas and constants. No make-up exams will be given.

Partial credit: Partial credit will be given to solutions of the problems that are partially incomplete, have minimal algebra mistakes, wrong sign, or units. The steps in the solution must be presented, and no grade will be given to a problem showing a solution (such as a number) without showing the intermediate steps to get there.

All exams are mandatory and no grade will be dropped or replaced.

There will be three exams, each given after discussion on electricity, magnetism, and heat.

Exams dates and times:
    Exam 1 - Thursday, October 10, 5:00- 7:00 pm, Chapters 21, 22, 23, 24, 25, 26
    Exam 2 – Thursday, November 7, 5:00- 7:00 pm, Chapters 27, 28, 29, 30, 31, 32
    Exam 3 (Final Exam) – Finals week, Chapters 17, 18, 19, 20

Homework

We use the Mastering Physics online homework system. Students may work in groups to do the homework. The online homework must be submitted by each student individually.

No homework grade will be dropped.

The deadline for each homework assignment is typically one week after it is assigned. Be advised not to wait till the last minute for the online submissions. It is your responsibility to submit your homework before the deadline.

MasteringPhysics.com advice and information:

• The procedures for self-registration are explained at www.masteringphysics.com (this is also the login site). Your access code is inside the student access kit that comes with the text (you will have to purchase one if you do not have the kit). The course ID is JTPHYS1220F2013. You may choose your login and password.
• Never use the browser's "back" button. Use the links provided.
• You will be able to submit each answer up to 20 times. Please hit "submit" after answering each question. Selecting "submit problem" will result in the problem being graded. Thus, selecting "submit problem" voids the option of additional attempts.
• Some problems have multiple components, so be sure to answer each portion.
• Many problems have hints to help you along the way. You will not be penalized for looking at the hints, and sometimes bonus credit (2%) will be awarded if you answer correctly without peeking at the hints. Either way, you win. Note that this possible bonus credit will be an extremely tiny fraction of your overall course grade, so please don't agonize over the choice.
• Some of the parameters in a given problem may be randomized. Do not assume that your friend's question has the exact same numbers as yours!
• There is a 2% tolerance for numerical answers; e.g., you can be off by, say, 1.8% and still receive full credit.
• Additional help for MasteringPhysics can be obtained through a document provided by the publishers. You can also access this at the course website.

Reading Assignments

You are required to read each chapter before and after it is discussed in class.

Register your cell phone number at http://www.polleverywhere.com

We will use cell phones or laptops for Q/A and other in-class interactions/practices. Register your cell phone or laptop. We will interactively discuss conceptual topics, and you will be able to vote on the answers to questions using your cell phones (or laptops). To register:

1. Go to http://www.polleverywhere.com
2. Create an account
3. De-select "I am an educator"
4. Select "United States" (not "United States - Education")
5. Once your account has been created, register your cell phone number (ignore this if you will use a laptop).
6. Go under "Settings" to add the number (with your area code). Follow instructions to certify your cell number.
7. Please allow me to see your name: Under "Settings" choose "Voter Registration". Select "Register as a voter". On the next page you should enter "jtang2@uwyo.edu".
8. Bring your cell phone or laptop to each class.
9. Standard text messaging rates may apply.

Disability Statement

If you have a physical, learning, or psychological disability and require accommodations, please let me know as soon as possible. Contact University Disability Support Services in SEO, room 330 Knight Hall.

Academic honesty

Academic dishonesty is defined in University Regulation 802, Revision 2 as “an act attempted or performed which misrepresents one’s involvement in an academic task in any way, or permits another student to misrepresent the latter’s involvement in an academic task by assisting the misrepresentation.” And there are rules and procedures to handle such cases, and serious penalties will be imposed. Note that a student who copies and a student who let’s another student copy are both covered by the university rules.

Grading
