Class Information
- Room: 70, Van Allen Hall
- Time: 11:30AM - 12:20AM MWF
- Lab Rooms: 361, 362 Van
- Discussion: 12:30-1:20 Th Room 70 Van
- Text: Fundamentals of Physics, Halliday, Resnick and Walker,
11-th Edition (Volume II). An ecopy of the text is included in Wiley
plus, which will be used for homework. You may get Wiley plus from the bookstore.
If you want a hard copy of the text the bookstore sells a
loosleaf copy of the text - you will still need Wiley plus for the homework.
Hard copies of the text are also available for purchase from
Wiley
or for rent from
www.CourseSmart.com .
- Lab Manual:Your will be given a lab kit during the first scheduled
laboratory. Write ups for labs are linked to this syllabus. There are
six scheduled labs that can be performed using the kits - more may be
added late in the semester.

Grading Policy
Possible final grades are A+,A,B,C,D,F,I. The grade of A+ is for
performance that is a full grade above an A. Grades are based on
homework scores (15%), lab scores (15%), two mid term exam scores (20%
each), and the final exam (30%). All exams will be graded by hand;
all grades will be curved to a mean of seventy and a standard
deviation of fifteen.
total score =
.15 (70 + (15/sd_lab)*(lab_score - mean_lab)) +
.15 (70 + (15/sd_hw)*(hw_score - mean_hw))+
.2 (70 + (15/sd_ex1)*(ex1_score - mean_ex1))+
.2 (70 + (15/sd_ex2)*(ex2_score - mean_ex2))+
.3 (70 + (15/sd_fex)*(fex_score - mean_fex))
The College of Liberal Arts recommends the following grade distributions
for intermediate level courses: A 18%, B 36%, C 39%, D 5%, F 2%.
These guidelines will be used as a first approximation in assigning
final grades.
Homework will be due on Friday's before 5:00pm. The homework
assignments use Wiley plus. They will be made available on the
Fridays before they are due. The exams, which are responsible for
most of the course grade, will be graded by hand. You must show your
work in order to get credit for your answer. The exam questions will
involve calculations and may also involve derivations. There will be
NO multiple choice questions. Because of this I recommend that in
doing the homework you get in the habit of writing out your solutions
carefully on paper before entering them in Wiley plus. This will help
you get used to my expectations for exam solutions. As physicists, or
more generally scientists or engineers, it is also important to be
able to communicate the steps and logic used in your arguments.
Writing out your homework solutions is good practice for developing
the type of communication skills that you will need as a professional
scientist or engineer. I will post written solutions to the homework
assignments on the class web page (after the due date) which will
provide an illustration of the kind of detail I would like to see in
you exam solutions.
Lectures, homework assignments, solutions, the course calendar,
and notices will appear on the web version of this syllabus
(http://www.physics.uiowa.edu/~wpolyzou/phys28/). It can also
be reached from the Physics Department's web page under course
web pages. There is also a link in ICON. The lectures will be
live streamed (see ICON) and recorded. The zoom IDs are
lectures: 954 5499 1700; discussion: 949 465 8368.
Participation in the laboratory portion of the course is required.
The grade of "I" will be assigned to students who miss more than one
laboratory. This semester, you will receive a lab kit during the
first lab that will be used to all of the labs. For students who are
unable to be on campus due to covid 19 these kits can used remotely.
You will have to make arrangements to pick up your kit.
General Information
This course is the second of four
introductory physics courses for physics majors. It covers
electricity, magnetism, and special relativity. The material covered
is in chapters 21-33 and 37 of the text. The prerequisites are 029:027
(PHYS:1701) and 22M:026 (MATH:1860). Elementary differential and integral
calculus will be used in the lectures.
The course is open to physics or
astronomy majors. It is approved for the natural sciences with
laboratory general education requirement.
