Introduction

Welcome to Engineering Physics II, for engineers and scientists. This is the second part of a course intended to introduce the fundamental laws and forces of nature. This semester we shall focus on thermodynamics, electricity, and magnetism. You will gain physical intuition and problem solving skills that will enable you to understand, explain, and predict physical phenomena.

Topics to be covered:

Disclaimer: This program is tentative and not definitive. Changes may be applied, and students will be properly notified in a timely way.

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 Law and electric potential
5. Capacitance and Dielectrics
6. Current, resistance and dc circuits
7. Magnetic field and its sources
8. Electromagnetic induction
9. Inductance and ac circuits

Required Materials

• The course will be based on the book: Sears & Semansky's University Physics 12th edition,  H.D. Young and R. A.Freedman, Addison-Wesley. The university has negociated a customized version for the course that includes only the chapters to be taught in this course, at a reduced price. Only available at the UW bookstore.
• Physics 1220/1320 Laboratory Manual, U.W. Physics & Astronomy, available at the UW bookstore.
• Mastering Physics: http://www.masteringphysics.com. Class code: AEF1220FALL11
• Poll Everywhere account for attendance and quizzes: Students 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). To make it so your names are visible by 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. (detailed intructions below)

Prerequisites:

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

Class Schedule:

"Physics at Night" help sessions will also be held six hours each week (MTW 7:00-9:00 pm in PS 239).

Lectures:

Since ideas and definitions from the text will be used freely in class, it is necessary for you to read and study the assigned chapters before class. I will avoid presenting the exact examples in your text. Instead, class meetings are for addressing the difficult points in the text as well as for helping to place the readings "in the big picture." The more actively engaged you are during class, the more you will learn and the better you will perform.

Discussion Sessions:

Whereas the lectures will focus more on general concepts, the discussion sessions will provide opportunities to review specific problems and and active environment to exchange ideas with your peers. You will also see a lot a practical problems and their solutions with actual numbers. Discussion attendance is mandatory and in your best interest: discussion section problems and questions will be used on exams and a attendance and quizzes account for a percentage of the total grade.

Laboratory:

Participation in each laboratory is essential for the successful completion of this course. If you must miss a lab, it is your responsibility to contact your lab instructor well before the date of your absence so that you may attend another lab section that week. If you are unexpectedly ill, contact your lab instructor as soon as possible to make arrangements. Laboratory participation is required, and you will get an Incomplete in your grade if you do not complete the 8 lab sessions. You must complete 8 labs to pass this course
There will be two or three make-up weeks during the semester, typically on an exam week.

Additional help

Except for finals week, tutors are available every MTWR evening from 7-9 pm in the Engineering Bldg (Rm 1045; wwweng.uwyo.edu/societies/tbp/tutoring/). "Physics at Night" help sessions will also be held six hours each week (MTW 7:00-9:00 pm in PS 239).

Grading (subject to revision):

Exams: 60% (3 exams --Thermo, Electricity, Magnetism)
Homework: (about 12-14 on-line) 20%
Labs: (8-10) 15%
Attendance and quizzes: 5%
Total: 100%

Scale: A: (> 90%) ; B: (80-90%); C: (70-80%) ; D: (60-70%) ; F: (< 60%)

Exams:

Homework will contain mostly quantitative problems, whereas lectures will provide you with largely conceptual, multiple-choice questions to tackle in class. Hence, the exams will contain both quantitative and conceptual problems, and have both multiple-choice and written formats. The exams will be closed book and closed notes. The instructor will provide a "cheat sheet" with useful formulas and annotations. Exams from previous semesters will be made available. 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 examinations are required and none of the scores will be dropped or replaced.

Exams dates and times:
    Exam 1 - Thursday, September 29 5:00- 7:00 pm, Ch 17, 18, 19, 20
    Exam 2 - Thursday, November 3 5:00- 7:00 pm Ch 21, 22, 23, 24, 25, 26
    Final Exam - Monday, Dec. 5 10:15-12:15, Ch 27, 28, 29, 30

Homework:

Assignments will be posted and graded online (below). A typical homework might include five to seven online problems. Typically, they will include five quantitative or conceptual problems plus 2 optional tutorial problems that will be considered a bonus. Students are encouraged to work together, but each student must submit their own work (see below). The deadline for each online homework will be indicated online.

Late written homework will not be accepted; a penalty of 50% will be assessed to the on-line homework if it is turned in 0-12 hours late, and no credit will be given if it's more than 12 hours late.

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 (please see me if you do not have the kit). The course ID is AEF1220FALL11. 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 three times, and full credit can be earned even on the third attempt (however, no credit will be awarded if you do not initially answer correctly on a two-part multiple-choice problem; partial credit only will be awarded if you initially answer wrong on a three-part multiple-choice problem, etc). 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 (3%) 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.

Entering formulas in Mastering Physics

Mastering Physics will ask you to enter algebraic formulas in your answers. You can use the graphic interface, but more likely, with time you will learn how to use shortcuts, and the MP symbolic language. Be sure to do homework #0 as a practice. Go through the MP tutorials and help pages. Here is a link to a nice resource: Mastering Physics help and tips

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

In-class quizzes and daily interaction will utilize cell phones or laptops to enter information and participate. Register your cell phone or laptop. Every day 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 "afeiguin@uwyo.edu".
8. Bring your cell phone or laptop to each class meeting.
9. Standard text messaging rates may apply.

What you should expect from me:

• To teach fundamental physics in a clear, organized manner to help you become competent and confident problem solvers. At the expense of skipping some of the later topics, I will reserve the option of slowing down the pace of the course according to the students' needs.
• To administer multiple feedback questionnaires, to better gauge your perceptions of the course and attend to your recommendations for my instruction.
• To encourage group learning in lecture with frequent conceptual questions to be discussed in groups. Research on how people learn physics STRONGLY indicates that lecture alone is NOT an effective way to learn. Effective learning requires interaction with the instructor and classmates.
• To incorporate demonstrations into some lectures.
• To expeditiously grade and return the exams to you.

How to be successful in physics:

• Work both independently and in groups of your peers who can help you understand the course material. If you need help finding a group of classmates, I will help connect you.
• Take each exam at the scheduled time. If you have a scheduling conflict due to a University-sponsored activity, it is your responsibility to inform the instructor well before the date of the exam.
• Make a good effort and to be prompt in completing homework and lab.
• Spend 12-15 hours per week to learn the material well in this course, including labs, discussion sessions, and lecture. Spend approximately 2-3 hours outside of class doing homeworks and reading the course material, for each hour you spend in class. If you are spending more time than this, please see the instructor so that we can ensure you spend your time efficiently.
• Be self-conscious of your weaknesses and strengths. Learn how to administer your time efficiently. Try to focus on a problem when you are working on the homework. Turn off your  TV, playstation, Xbox, your Wii. Don't look at your facebook for a couple of hours.  If you have difficulties focusing, or your attention span is less than 10 minutes, be aware that it may affect your performance in class, and your career.
• Work as many problems as you can beyond the assigned homework. As with everything in life, practice, practice, practice, ...
• Read, read, read...
• Attend and participate in each lecture, laboratory, and discussion session. It is your responsibility to obtain and understand the material presented, even if you are not in attendance due to illness or a University-sponsored activity.

Absence policy:

• Attendance to office hours is strongly encouraged.
• Attendance is advised, and highly recommendable. Students are expected to attend all lectures.
• Lab attendance is required

Academic integrity:

University Regulation 802, Revision 2, http://uwadmnweb.uwyo.edu/legal/Uniregs/ur802.htm defines academic dishonesty 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." There is a well-defined procedure to judge such cases, and serious penalties may be assessed.

Classroom decorum:

Unireg 29, Change 1, http://uwadmnweb.uwyo.edu/legal/Uniregs/ur029.htm states that the student has obligations as well as rights in the classroom.

Cell phone policy:

Cell phone use is not allowed in class. They should be turned off, or into vibration mode. Calls will only be allowed in case of an emergency situation.

Use of electronic devices in class:

Use of I-pods, mp3 players, cell phones, and texting are strongly discouraged. Any disruptive behavior related to the use of electronic devices will be considered unacceptable. Please, respect your peers.

Students with Disabilities:

If you have a physical, learning, or psychological disability and require accommodations, please let me know as soon as possible.  You will need to register with, and provide documentation of your disability to, University Disability Support Services (UDSS) in SEO, room 330 Knight Hall, 766-6189, TTY: 766-3073.
