__General Overview__

Instruction for this course begins
with the first lecture Tuesday Jan 20 1:00 - 2:20 pm 151 Loomis

Your first discussion meeting is
the following week, Monday evening Jan 26. You should go to the section you are registered
in, as space is limited. Attendance
at these discussions is part of your grade.

The course schedule (subject to
change) can be found here.

Physics 325 is the first half of
the complete classical mechanics sequence (Physics 326 is the second
half). Physics 325 will probably
require more work than your previous physics courses and is a serious departure
from "the plug-n-chug from the formula sheet" mode of operation to
which you may have become accustomed.
You will be deriving analytic expressions, and learning to critique and
interpret and apply them. I expect
you to know first year calculus thoroughly and be prepared to go beyond that
level. Topics such as matrices,
vector mathematics, multivariable calculus, and differential equations covered
in PHYS 225 will be assumed.
Concurrent registration or completion of Math 285 or equivalent is also
expected.
Here are links to a couple of collections of math and physics
formulas that you may find useful during this course, some of which you may
recognize.

__Syllabus__

The
course schedule, and by implication the coverage, can be found here. Watch that site for changes.

__Texts__

* Taylor, Classical Mechanics Required

* Marion and Thornton, Classical Dynamics of
Particles and Systems. Optional

(the fifth edition is best, but earlier
editions are also fine and much less expensive)

* Approximate
Lecture Notes (available at
Kinkos/Fed Ex on Wright Street?)

(photocopy of last year's lectures) Optional but highly recommended.

The two books should be on reserve
for PHY 325 in Grainger Library.

__Online access__

Some of the on-line activities
(e.g. gradebook; see the link above) for this course run on a secure server and
must be logged into.
Students enrolled in (and staff associated with) the course must log in
using their UIUC NetID and their NetID password. If you are enrolled in the
course and are having trouble logging in, send email to Rebecca Wiltfong
rwiltfon@illinois.edu. You should always log out of the secure server at the
end of your session.

__Lectures__

Lectures will be held on Tuesdays
and Thursdays from 1:00-2:20 pm in 151 Loomis. It is highly recommended that
you read the Approximate Lecture Notes and the relevant sections of the text
before each class.
Up-to-date Lecture notes will be posted after each lecture at the course
website.

Attendance is expected. Almost every lecture will
conclude with a very short quiz related to that day's material. This will be graded only for
attendance. Solutions will
be posted as part of the notes.

__Discussion Problem sessions__

The problem sessions will take
place weekly on Monday evenings and will last for one hour. There are six
sections, each lasting one hour every Monday between 4 and 9 pm.

You are registered for one of
these (Space is limited, so go to the section for which you are registered.).
Attendance at your Monday evening problem session is obligatory. Show up on
time to receive full credit.
WeÕll take 15% off the credit for each 5 minutes of being late. If you
are late by more than 30 minutes you will not receive credit. You will be able to access
the problem session materials and solutions through the course schedule page,
but not before class. The
idea is that you work out the problems in groups, so doing them before class is
not advised.

__Homework__

Homework is an essential part of
this course. HW instructions PDF The homework to be done will usually be handed out at
the beginning of the each Thursday lecture and will usually cover the lecture
material of that day and the following Tuesday. I will collect your solutions at the beginning of lecture
one week later. (See the course
schedule page for details.) You
may also place your completed homework in the yellow PHYS 325 box located at
the beginning of the second floor "Interpass" in Loomis, but it must
be in the box by 1:00 pm on the day that it is due to receive full credit. Late work will be marked down by 15%
each day that it is late and will not be graded if it is more than one week
late. If you do hand in your HW
late, email the graders to tell them when you did so, otherwise it will be
assumed to have been deposited just before the grader checked the box. I don't object to people working on the
homework problems together (some years students have set up a facebook page for
the course) as long as the work that you hand in for grading is your own. I strongly recommend
that you thoroughly struggle with the problems yourself first. You'll learn
more this way and you'll do better on the exams when you're on your own. Neatly written readable HW
will help both you and the grader understand what you've done.

You will be able to access the
homework assignments electronically through the course schedule page as well as
by hardcopy at the lecture.

Each week there will be two
distinct HW sets. A and B -
on pink and green paper respectively in the handed out hard copies. They should be done separately, stapled
separately, and handed in separately. Please staple the problem page to the front of the
pages you hand in.

__Exams__

There will be two midterm exams
and one final exam. Dates times
and places will be announced.
Please check the course schedule calendar for full details.

__Office hours__

Office
hours start the week of Jan 26 and are during the following times and in the
following locations (watch for changes):

You are welcome to arrange
appointments (use email to set time and place) when these hours are not
suitable.

Special office hours may be set up
before exams

__Grading__

Your course grade will be based on
your homework (~33%), exams (~17,
17 and 26%) , lecture attendance (2%)
and attendance in weekly problem sessions (~5%). There will be two midterm exams and a
final exam.

__Academic Integrity__

The giving of assistance to or receiving
of assistance from another person, or the use of unauthorized materials during
University Examinations can be grounds for disciplinary action, up to and
including expulsion from the University.

Please be aware that prior to or
during an examination the instructional staff may wish to rearrange the student
seating. Such action does not mean that anyone is suspected of inappropriate
behavior.

Exams will all be closed book with
no calculators, though a short list of relevant formulas will be provided. You will be permitted, even encouraged,
to prepare and bring one page of your own notes.

Unless a HW problem explicitly
states otherwise, you are not to use any calculating devices or symbolic
manipulation tools in any of your work. No calculators, no computers, no slide rules. And no use of electronic search tools
to find solutions to problems you are working on. I will only permit paper and pen, and information you
can find in course notes and textbooks and reference works and tables of
integrals. You are on your honor to hold to this.
