POLICIES:
Preparation Read
sections of text (listed on web or Moodle) BEFORE
they are covered in class. Give me feedback about what was totally easy
and what was particularly confusing, so I can tailor the class to your needs.
Homework to
be graded should be turned in to me in person, or to my mailbox, by
Please
do not slide assignments under my door!
Show all work and justify all answers on homework and exams. Be prepared to
discuss assignments in class.
Attendance
is required on all days on which exams or discussions are scheduled. If you have
a conflict with a schoolrelated event, you may take an exam early. You
must make arrangements with me before the scheduled date. Attendance is highly
recommended on all class days, as the book will be supplemented by lectures and
handouts.
Final exam
is worth the same amount toward your grade in the course as the midterm exams.
3/4 of the points on the final will be questions on topics covered after the
second exam. 1/4 will be review questions on the topics covered by exams 1
& 2.
Prerequisites:
PH201203 and calculus!
Important events (subject to change  check web for
updates and details):

PHYSICS 301 PREPARATION
1. Observe the motion of the toy cars. When the red car is in front of the police
car and both are traveling in the positive direction, the velocity of the red
car relative to the police car is ___ and the velocity of the police car
relative to the red car is ___.
2. Observe the motion of the toy cars. When the red car is behind the police car and
both are traveling in the positive direction, the velocity of the red car
relative to the police car is ___ and the velocity of the police car relative
to the red car is ___.
3. Find the derivative of 3e^{4x} with respect to x.
4. Find the derivative of xe^{4x} with respect to x.
5. Given the following graphs of a wave function as a function
of position (x) and time (t):
t (s) x (m)
a) Estimate
the wavelength of the wave. b) Estimate the frequency of the wave.
c) Estimate the wave speed.
6. Very briefly describe what causes interference pattern when
light passes through a double slit.

spots that are dark?
7. Under what circumstances is energy conserved?
8. Under what circumstances is momentum conserved?

moon would feel ___ gravitational force.
Assume the moon to be at the same distance from center of Earth.
10. Light has ___ electric charge and ___ mass.
