Douglas Giancoli, "The Ideas of Physics", 3rd edition, published by
Brooks/Cole
The textbook is required. This text has been unchanged for several
years (but can be found with a variety of different formats, my copy
says copyright 2001). There
are many
copies available second hand in auction sites and online booksellers.
The book should not cost you a lot of money - $20 should buy
a decent copy.
Note that the material that
will be covered in
the tests
is that covered in class. Although the order of the book is followed,
some subjects may be expanded upon, and some may be shortened.
One purchase that you must make (in
order to get full points!): -
An H-ITT remote. These are obtainable at the bookstore. To make sure
that you have the correct one look at this website. Physics
H-ITT
remotes Follow the links on the remotes
website to see
how to
register
and use them.
We will not start using them for credit until drop/add is over, but if
you have them,
bring them to class.
Friday, January 7 John Mocko will teach you all how the remotes work
in this class, so definitely try to have your remote by then.
The
remotes will enable you to take part in the in-class multiple choice
quiz questions that
are generally given every
lecture period, and constitute 10% of your grade.
Grading policy.
Maximum total possible 100 points. a)
Tests There
are 2 in-class tests during the semester, each
of which are 30 points. There is a 3rd exam (the 'freebie') given in
class the last day of class, Wednesday April 24. This 'last
chance' exam is like a practice final, and is used as a makeup for
students who missed a test or
for students who want to try to improve one of their test scores.
There is a two
hour final
exam, worth 30 points, given Thursday, 10:00 am - 12:00
pm, May 2
(final test time assigned by the registrar). That gives 90 points from
tests, that is 90% of the grade is in tests.
The 2 during-the-semester tests will be in a "short-answer" format - not multiple
choice.
Both the 'freebie' and the final will be
multiple choice using bubble sheets. Essential formulae will
be
supplied for the tests. In addition, you may have one (1) crib-sheet
for each of the 2 in-semester tests. Save your crib sheets,
you
may have three (3) crib sheets for the 'freebie' and for the final.
All tests are closed book.
b) In-class Quizzes Use of the H-ITT
clickers is worth 10%
of the grade. Each question is worth 2 points for a correct answer and
1 point for a wrong answer. One quarter of the questions are dropped.
This generous drop policy is meant to cover all excused
absences (religious holidays that are not U of F holidays but which you
observe, illness, sponsored U of F activity where you have to be away
like a team sport, interviews, weddings, ... If after these
absences you have any drops left, then low scores on quizzes you took
will be dropped.)
Giving your H-ITT clicker to someone else is considered
cheating!
The following is the guaranteed grading scale - 80% for an "A", 75% for
an "A-", 70% "B+", 65% for a "B", 60% for a "B-" 55% for a
"C+" 50% for a "C", 45% for a "C-", 40% for a "D+", 35% for a
"D",
30% for a "D-". Below 30% is an "E".
Philosophy of the course
This course is designed for people who do not necessarily have a
background in physics.
We accent the physics of everyday life. Hopefully this can
serve as
a foundation that
will help if you are going to take, for instance, PHY2053 or PHY2048,
as well
as being a good survey of the basics of physics that will stay for you
for the rest of your
lives. There is no obligatory homework (but there is recommended
homework). Students who
have a good background can do well in this course putting in relatively
few hours of work. However, if you do not attend class, you will not
only miss the opportunity of getting 10% of the grade, you will also
miss the explanations and examples that it will be necessary to
understand for the tests. The course moves FAST - often one subject
(1/2 of a chapter) per class period.
If you miss class, you will miss an entire subject - be warned.
Calender of Events You may print this
out, but be aware it can change as the semester
progresses,
depending on how long we take on each subject, how well people do in
tests,
etc. The test dates are also preliminary.

Hints on how to do well:
Attend Class Remember, the syllabus is
defined
by what is covered in lectures. You will not be tested on material not
covered in class. The book covers lots of material, not all of which
you are expected to know. If you miss class, my advice is to ask a
class-mate
for notes. I am happy to explain things in office hours which you did
not understand.
Be on time for class. Announcements are
generally made at
the beginning
of each lecture, and you are responsible for learning of these whether
you attend class or not.
If you are struggling, ask for help. The
best way to get
hold
of me is after class, in our assigned office hours, or by e-mail. It is
tough to discuss physics by e-mail, so it is better to ask 'how to
solve this problem' in office hours so I can understand what you're
missing. If you want to discuss physics and cannot make time
during my office hours, I can be flexible, but check with me first.
Take Notes Something that is obvious at the
time is quickly
forgotten. When it comes to the night before a test, you will
appreciate a good set of lecture notes.
Do some problems Here are are a sample of physics
problems, and their
solutions,
taken from the textbook. Really try to work some of these problems
without looking at the solutions after a short time - otherwise the
exam problems will seem challenging. Note that they are just samples
for extra practice, although I promise that doing some of them will
improve the score of everyone who is not a born 'A' student in physics.
Another great way to be ready for the tests is knowing notes
taken in class inside and out.
