Classical PhysicsPhysics 140, Fall 2004Professor SullivanEmail: sullivan@kenyon.edu |
 This
lecture course is the first in a three-semester, calculus-based,
introduction to physics. Topics include the kinematics and dynamics of
particles and solid objects, work and energy, linear and angular
momentum, gravitational, electrostatic, and magnetic forces,
oscillations and waves, and direct current circuits. The two,
semester-long courses that follow this are PHYS 145 - Modern Physics
and PHYS 240 - Fields and Spacetime. A co-requisite for this class is
either (for first-year students) PHYS 110 - First Year Seminar or
(for upperclass students) PHYS 141 - Introduction to Experimental
Physics. In addition, you must either have already taken, or
placed out of, or (more commonly) be taking concurrently, MATH 111 -
Calculus A. |

| The textbook for the course is "University
Physics" by Young and Freedman. This is the first year that we have
used this text, so your feedback will be very welcome. I know that the
textbook is expensive, though comparable to other such texts. It is
also likely (though not certain) that it will be used in one of the
follow on classes in our introductory sequence. If you
continue in your study of physics, you will find the book a useful
reference for years to come. So the high price is amortized somewhat.
The textbook will be a source of reading material to augment my
lectures and will be the primary source of homework problems.My
grading scale is absolute, that is, there is a fixed relationship
between percentage scores on homework and tests and your grade. A
consequence of this is that you are not in competition with
other members of the class. In fact, I encourage you to form study
groups and work with others on homework and as you study for exams.
Your peers can teach you a great deal and you can deepen your own
understanding when you teach others. But there is a limit to
cooperation. Anything you
turn in to me must reflect your own work and understanding. You cannot
just
copy another's words and derivations even if they are the result of
group
effort. A surefire way to avoid trouble is to prepare the material that
you
do turn in alone and without notes from your group study session.
Simply
turning in the results of others work is unhelpful (homework is not
that
big a percentage of the final grade and you don't identify problem
areas
before an exam where it will have a big impact on your grade) and also
constitutes
plagiarism and is subject to sanctions by the Academic Infractions
Board.
If this is unclear, please be sure to ask me about it.There are four components of
your final grade: weekly homework (10%) and four, equally-weighted,
two-hour midterms (each worth 22.5%).
We will have to hold three of these exams in the evening so that you
have
two hours available. These exams will be held on Wednesday, September
29th,
Wednesday, October 27th, and Wednesday, December 1st, all at 7:30PM.
The
last midterm will be held at the time scheduled by the Registrar for
our
final exam, namely Saturday, December 18th at 9:30AM. Let me know by
the
end of class on September 6th if you have a conflict with any of these
exam
dates. Attendance at lectures is not a factor in the final grade,
however, good attendance is highly recommended and you are responsible
for
all material presented in class. There will be weekly homework problems due each
Friday at the beginning of class. On the preceding Thursday evening
there will be a "help session" led by an upperclass physics major. Do
not be fooled by the small weight given the homework in the final
grade. In physics, homework is to tests
like practice is to games in sports. You don't get much credit for
practices,
but you can't expect to do well in games if you haven't practiced. When
you
do turn in homework, don't just give a list of equations and the
calculation
of the answer. Explain your reasoning in words using complete
sentences.
Doing this will both increase your understanding and give you practice
in
science writing. Homework is a chance to get feedback on the learning
process.
Close the feedback loop by going over returned homework and getting
help
on weaknesses that have been identified.Late homework will be
accepted up to one week after they are
due, but with a penalty to encourage you not to get behind. If your
homework is turned in between the start of class on the day it is due
and the time that I transfer the papers to the grader, the penalty will
be 10%. If handed in after that time, but before the beginning of
class one week later, the penalty will be 20% and will be graded when
convenient for the grader.I want to do everything that I can so that
everyone is able to fully participate in class and has a successful
experience in physics. Please contact me immediately if there is
anything preventing your free and open participation in class.
Additionally, if you have a learning disability
and need accommodation, I encourage you to contact me, but you also
need
to contact Erin Salva (Coordinator of Disability Services, x5453,
salvae@kenyon.edu) well in a advance of any need for accommodation to
determine appropriate
and effective accommodation.I also believe that each of you own a piece of
me for the price of your tuition and I enjoy getting to know all of you
a little better. Please do not hesitate to take advantage of my office
hours (MWF immediately after class and TTh 4:10-6PM). If you have a
conflict during all of my office hours please contact me to arrange an
appointment. Or just drop by my office in Hayes 206. I spend a lot of
time in the department and if my door is open, I will be happy to talk
to you. |
