people who are seriously considering a major/minor.

- The main textbook for the class is Physics for Scientists and Engineers,
by Serway and Jewett (6th, 7th, or 8th
editions). You will need a textbook, or combination of textbooks, that covers
chapters 14, 16-22, and 35-39. Inexpensive used versions are perfectly
- A small auxiliary textbook will be Physics phor Phynatics,
by Dallin Durfee (a faculty member here at BYU). This book contains
supplementary material specific to this section of 123. It is a very inexpensive
book, and Dr. Durfee does not receive any royalties.
Syllabus and Course
Phys 123 section 2
syllabus.pdf - The syllabus will also be available in the bookstore for purchase, for
you prefer, you can print out your own copy from the pdf file. (But if you
do so, please don't use department printers unless you reimburse the department
for the expense.)
- Some students like to print out lecture notes before the lectures, for
use in taking notes. If you want to do that, you can use
my lectures from last semester. This semester's lectures will likely be
fairly similar to those lectures.
- After each lecture this semester I will post the lecture notes I
actually used, for you to use in reviewing material.

Here are a lot of the demos I have done/likely will do in class this
semester, posted here in case you have to miss a class. The videos were
filmed in old Phys 123 and Phys 105 classes. Click on the demo title to get it to play in the

- Instructions for all the labs, along with the sheets which must be
turned in, can be found in the main syllabus packet following the
homework problems. Due-dates for the labs are shown on the main
schedule, the first page of the syllabus.
- All but two of the labs are similar to the "walk-in" labs of Physics
121. They will be set up in room S415 ESC on the dates indicated on the
- Two of the labs involve computer simulations. Follow these links to

Here are some old exams for you to use as study aids. There's no guarantee that
this year's 123 exams will be the same as any of these posted exams, in
terms of multiple choice/not multiple choice, time limit/no time limit, notes/no
notes, calculators/no calculators, difficulty level and so forth. For
example, this year I am not letting
students use any notes on the exams, but rather I will provide
some (but not all!) equations on the first page, like this
sample first page of exams.

to get started
- You need to do the following things as soon as the semester begins. (If you
have added the class late, it's even more important to do them ASAP.)
→ If you have not received one in an email, get a "class ID number" using the "Obtain your class ID
number" link on this page. You will use the CID as your personal identifier for all your
→ Read the syllabus, available either as a pdf file elsewhere on this
web page, or from the bookstore. Among other things, the HW problems are found in the syllabus.
→ Get a copy of the Serway & Jewett textbook (see textbook info, elsewhere on this web
page). If you can't get one
soon, you can use one of the copies available in the Tutorial Lab (see Tutorial Lab info
elsewhere on this web page).
→ Do the reading assignments for each upcoming lecture as marked on the
schedule on pg 1 of the syllabus;
if joining late, do the past reading assignments.
→ Get an "i-clicker" at the bookstore if you don't already have one. Bring your
clicker to each class.
→ Register your clicker (via the link elsewhere on this page) so that you get credit for in-class clicker
→ Get your individualized homework data numbers which you will plug into the HW
problems in your syllabus, using the "Print HW data sheet" link on this page.
→ Start working HW problems! The first assignment is due Wed,
Sep 1. You can get credit for late assignments, so work
the HW sets you miss/have missed, in addition to the ones coming up. The syllabus
has much more
about how to turn in HW problems.
→ Where required, submit your computer-graded HW answers via the online system using the "Submit HW" link. Again, read
how to do this in the HW section of the syllabus. Learn how to get partial
credit by re-submitting the problems you get wrong. Talk to other students to
figure this out, if necessary. HW due-dates are marked on page 1 of the
→ Be sure to turn in the work for your HW problems to the slot labeled
“Phys 123, section 2” in boxes near room N375 ESC.
up for a departmental computer account if you don't have one already.
→ Gain access to the departmental computer labs (N337 and N212) by talking
