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 thermophysics, electricity and magnetism

 

Prerequisites:

Grades of C or higher in PHYS 1210 (or equivalent), MATH 2200 and 2205 (Calculus I & II) and concurrent enrolment in MATH 2210 (Calculus III)

 

Topics to be covered:

1.                  Temperature and heat

2.                  Thermal properties of matter and ideal gas

3.                  The first law and second law of thermodynamics

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

5.         Current, resistance and dc circuits

6.         Capacitance and Dielectrics

7.         Magnetic field and its sources

8.         Electromagnetic induction

9.         Inductance, ac circuits and electromagnetic waves

 

Discussion Sections

Whereas the lectures will focus more on general concepts, the discussion sections will provide opportunities to review specific problems and interactive 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 problems and questions may be used on exams.

 

Labs

We will have a total of 5 labs.  A brief instruction for each lab is provided here (Labs 1, 2, 3, 4, and 5) along with the guidelines for the lab reports.  Participation in all labs is mandatory (note Labs 4 & 5 are virtual labs) 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 week (Note, there is no more make-up lab week scheduled for this semester).  In order to pass the course, you have to take part in ALL laboratory sections.  No lab grade will be dropped.

 

Exams

Homework and discussion problems 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 thermophysics, electricity and magnetism.

 

Exams dates and times:
    Exam 1 - Thursday, February 27, 5:10 - 7:10 pm, Chapters17, 18, 19, 20     

    Exam 2 – Thursday, April 16, 5:10 - 7:10 pm, Chapters 21, 22, 23, 24, 25, 26   

    Exam 3 – Tuesday, May 12, 10:15 am – 12:15 pm, Chapters 27, 28, 29, 30, 31, 32

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.

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.

Regarding Disability

If you have a physical, learning, or psychological disability and require accommodations, please let me know as soon as possible. And 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

                        Exams:  60% (3 exams – 20% each on thermophysics, electricity, and magnetism)
