Working together on homework is appropriate. However, it is expected that all work you
submit for a grade for this course will be substantially your own.
Students with Disabilities: In accordance with University policy and the Americans
with Disabilities Act (ADA), academic accommodations may be made for any student
who notifies the instructor of the need for an accommodation. It is imperative that you
take the initiative to bring such needs to the instructor’s attention, as he/she is not legally
permitted to inquire about such particular needs of students. Students who may require
special assistance in emergency evacuations (i.e. fire, tornado, etc.) should contact the
instructor as to the most appropriate procedures to follow in such an emergency. Contact
Disability Support Services at 298-2512 for additional services.
Course Objective and Outline:
We will study the nature and applications of one of the most interesting and useful forces
in our world – Electricity and Magnetism. We will draw on the concepts we developed in
197 related to kinematics and dynamics. In addition, we will develop several new
concepts, including the ideas of a new property of matter – “charge”, and of a spacefilling “field”. The field concept in particular will require that you use your integral
calculus in more sophisticated ways. The applications of these ideas are too numerous to
count, but we will focus our attention on electrical circuits and electrical energy. Perhaps
the most amazing application of the ideas from this semester will be developed only next
year, when you learn how time-varying electric and magnetic fields give rise to waves
traveling at the speed of light! So, we have a lot to do and a lot to look forward to. Let’s
have a good time along the way!
Homework:
The best way you can succeed in this class is by doing your homework regularly,
completely and carefully. Homework serves a lot of functions. Getting the right answer is
only one of them. Among the other things that homework can help with are: 1)
Developing a clear and consistent method of analyzing and solving physics problems, 2)
Learning how to present your thoughts, analyses and solutions in an understandable and
consistent fashion, 3) Learning how to go beyond the stated question and asking “What
if?” to push your understanding of the concepts at hand. You might think that all 100%
of the points should be associated with doing homework! But, that’s not practical. You
just have to believe me that doing homework well can impact your grade and
understanding 100%!
This semester, we will use WebCT as a way to ease your load on writing up homework
problems. The homework set will consist of around four to six problems to be done
online as a WebCT quiz, and three to five problems that should be written up and handed
in to be graded. The quizzes can be taken multiple times. You get full credit for the
WebCT quiz only by doing all of the problems correctly before the due date. The
handwritten assignments will be graded by hand, and partial credit will be assigned. I
hope that in this way you will gain sufficient mastery of the basic techniques without the
tedium of writing up the problem on paper, while at the same time continue to develop
your analytical and logical skills in solving more complex problems. The homework
grade will account for 20% of your final grade.
In addition to the WebCT problems available online, do the following pencil and paper

Final Exam, May 10th, 10AM
Pre-Lecture Reading Quiz: Before each lecture, there will be a quick quiz type problem
which you should respond to by 10 AM the morning of the lecture on MWF of each
week. Your responses will help me understand what your level of comprehension is after
reading the material in the chapter for that day’s lecture. You will be graded on two
aspects. First, on simply taking the quiz, and second, on whether your response indicates
some seriousness of thought. The reading quiz is worth 10% of your total grade.
Laboratory Experiments:
Attendance at Labs is mandatory. You will be allowed to make up one laboratory for an
excused absence, if you make arrangements ahead of time. Lab reports will not be
accepted if you did not attend the lab. The laboratory portion of the course will consist of
11 experiments. A quiz will be given at the beginning of each laboratory session. The
quizzes will be worth 10% of the total lab grade and will be based on the material in the
lab manual. Following each lab exercise you will be given a lab report which is to be
completed (using the data acquired during the lab) and turned in to the physics
department office, CH 212. Lab reports for Tuesday labs are due the following Friday. If
a lab report is turned in late, 10% of the credit will be lost for each day late.
Each student must complete all 11 lab exercises and turn in all 11 lab reports. If you do
not, you will fail the course! Missed labs should be made up according to the Lab
Instructor’s schedule, within one week of the lab. Only ONE lab may be made up for
credit, but ALL labs must be made up to pass the class.
You must use a bound laboratory notebook to record your work in lab. Also, bring a
pen and calculator to lab each time you come. Everything that you do in lab should be
described and recorded carefully in the lab notebook in pen (not pencil). The lab
reports may be completed using a pencil, however. You or anyone else should be able to
look at your lab book several days or weeks later and understand what you were doing in
the lab. The notebook (your record of activities in the course of doing the lab) is worth
one full lab report. It will be collected once at the end of the semester. The lab component
will be worth 15% of your grade.

Exams:
There will be three in-class exams and a final exam. Each in-class exam will cover one
unit of material. The midterms will be worth 10% each. The final exam will be
comprehensive and worth 25% of your grade.
Grading Policy: The labs, homework and quizzes will be graded on a 90,80,70,60 scale.
Exams will be graded on a curve, with an anticipated scale of 85,75,65,55. The final
grade will be determined using a weighted average of the homework, lab, quiz, in-class
and final exam scores.
For example, if you scored an 85% on HW, 80% on lab, 80% on quizzes, 75% on each
of the in-class exams and 85% on your final, the final percentage would be:
(.20)*.85 + (.15)*.8 + (.10)*.8 + (.1)*.75*3 + (.25)*.85) = .8075.
The grade is found by doing the same calculation for the cut off scores for an A, B, C, D,
etc., and comparing your score to the cutoff scores. The exam scores are the only
variable, since the cut offs will be determined based on the curve for each exam.
