All links to solutions will be taken down at the beginning
of the spring quarter.
Grades are available in Tycho. Have a good break! Final exams
can be picked up from what was Laura Clement's office,
and is now Helen Gribble's office.
Solutions to the final exam (for all but the lab question)
available on the solutions link. There is an error in the solution for
question 7---the words are correct [ B is correct]
but the wrong letter is circled. If you checked your MC score earlier,
you may find that it has changed by 5 points as a result of correcting
this error in the solution key.
Final clicker scores are in "Hitt04". These are
the fraction of the total available points for the whole quarter.

Welcome to PHYS 122, the second of a three-quarter sequence of
physics courses. You should find this
course challenging and stimulating. This quarter the material
will be somewhat more abstract and involves somewhat more calculus.
I hope that you also find it to be interesting and enjoyable.
Have a great quarter!
The course design is a cooperative effort of many faculty.
Each element of the course (lecture, lab and tutorial)
is important for your mastery of physics. The three elements are
coordinated, but are not necessarily synchronized. Research has shown
that presenting material in cycles, so that the same topic is approached
more than once from different viewpoints, is a very effective means of
encouraging deeper understanding and long-term retention of ideas.
We will continue to use
clickers (infrared responders) to get feedback in class.
The aim is to make lectures more interactive, and thus useful.
Each quarter, the UW Office of Educational Assessment conducts
of undergraduate courses. For many years, the PHYS121-2-3 courses have
been among the courses reportedly requiring the most hours of work per
week outside of class. The typical range is
from 5--20 hours of study per week outside of class.
This is a challenging class!
Note that PHYS 121 is a prerequisite for this class, and that
MATH125/128/134 or 146 (Calculus II)
is a prerequisite/corequisite.
Please be aware that many technical majors have a minimum grade
a core of lower-division technical classes including the PHYS121-2-3
Therefore, each student is strongly urged to discuss
entry requirements with their undergraduate or departmental advisors,
plan their course loads accordingly.
Memorization of material is not particularly helpful in
this class. Your goal in this class should be to understand how each
new topic is related to all of the previous material, and how the
concepts, rules and formulae can be applied to solve real-world
problems. Never let anything go by if you do not
understand. Generally, ask questions immediately. If it is
inconvenient to interrupt, make a quick note to yourself and inquire
Students are encouraged to
gather and work cooperatively in small groups in
the Physics Study Center, located in Room AM018

in the tutorial room. Completion of pretests will
be a factor in determining your course grade.

Grading policies will be explained in your tutorial section.
There will be three 50 minute midterms (during class time on
Monday Jan 22, and Fridays Feb 9 and Mar 2)
and a two-hour final exam (Thursday, Mar 15, 8:30-10:20am).
All will take place in the lecture room, A118.
Each exam will consist of various types of problems:
some similar to the Tycho homework,
others based on material discussed in the tutorials and similar
to the tutorial worksheets and homework,
and others related to laboratory experiments.
There will be a roughly equal mix of multiple choice and standard
The one-hour exams will emphasize the material covered
in the prior two or three weeks,
but may include earlier topics too.
The final exam will be comprehensive.
The standard cover sheet for exams is

are to be your own work; you are not permitted to collaborate with any

If you think there is an error in the grading of
an exam, or in the adding up of points, you
may return your exam for regrading.
To do so, you must resubmit the exam no later than
the lecture following the one in which
the exams were returned. Attach a brief note to the
exam (if you wish, using the

quarter to establish alternate examination procedures. Students who
miss an exam without making prior arrangements with the lecture
will drop that exam score. Except for extreme circumstances, a final
of 0.0 will be assigned to any student who misses two midterm exams.

will receive a combined grade for lecture, tutorial and lab. The final
course grade is based on the best two of three midterms, the final
the Tycho lecture HW, tutorial participation and HW,
lab participation and reports, and
lecture exercises (using the infrared response system).

may be found
In addition, a grade of 0.0 will normally be given to students
who do not take the final or who miss two midterms.
After the raw grade has been determined following the above-mentioned
policy, I will adjust the grade based on records from the lecture response
system. After a ``break-in'' period
(probably the first two lectures), from which responses
will not be counted, each response you give will count for one point,
with an additional point if you get the correct answer. These points will
be tallied at the end of the quarter, and will be used to adjust
your grade upwards or downwards by a maximum of
0.1 grade points. Students obtaining 75% or more of the maximum
possible points will receive the maximum upwards shift. This allows
you to miss a few lectures, or have your battery go dead, and yet
still attain the maximum "clicker" score.
To receive this adjustment you must have registered your clicker
at some point during the quarter (see above).
