Topics and Outlook:
This course will introduce the basic ideas of Newtonian Mechanics. This is a very large
and interesting area of physics, and after the completion of this course you will understand
the application of many areas of physics. We will begin with a thorough discussion of
motion, including motion under the influence of gravity. We will extend our analysis from
simple motion in a straight line to motion along more directions, for example by considering
the trajectory of a projectile like a cannonball. After this, we will ask, “where does this
motion come from?” “What makes things move?” The answer to these questions is found
in Newton’s laws of motion. These three laws really encompass all the main ideas of motion
- everything else is application, and can be obtained from these laws, as we’ll see. Following
our discussion of Newton, we will then discuss one of the most important concepts in all of
physics - the conservations laws. We will see that there are some quantities that, no matter
how we twist and turn our system, these quantities always stay the same. Examples of
these quantities include energy, momentum, and angular momentum. Using these quantities
makes solving problems considerably easier. Next, we will consider fluids such as liquids
flowing through pipes and the air pressure at various heights, ending with a basic discussion
of elasticity. Next, we will discuss gravity in much more detail, discussing how planets
orbit the Sun as well as some very interesting applications of gravity, including black holes.
We follow gravity by a discussion of systems which are vibrating, which turns out to be
an extremely important area of physics because, as we’ll discuss, many systems (such as a
pendulum, electrical circuits, and even electrons in an atom) can be described as a vibrating
system. Depending on the timing of the topics, an occasional special lecture on an interesting
topic will be presented.

Attendance: Attendance is essential to your success in physics! Because physics builds
upon itself, missing one lecture can affect your understanding of all that follow. If you
are absent for more than 9 consecutive hours during the first two weeks, then you may be
dropped from the course.

The grading will be based on the final (25%), 12 quizzes (50% total), and the
discussion/lab sessions (25% total).
- Tentative Grading Scale A
85% – 100%
75% – 84%
65% – 74%
55% – 64%
Below 54%
There will be 12 quizzes, each held during the lab/discussion sessions on Mondays
(except for Wednesday, September 5th and November 14, since those Mondays are holidays).
We will do our best to give plenty of partial credit, so always attempt the problems, even if
you don’t finish them!
Final: The final exam is scheduled for Wednesday, December 12, from 12:00 – 2:00,
and will be comprehensive.
The quizzes and final exam are closed book. If some complicated formulas are needed
(such as a nasty integral) they will be provided, as will any required numerical values, etc.
You may use calculators. You should bring your student ID along so that your identity may
be verified, if necessary.
Discussion/Lab Sessions
Part of the course includes a discussion/laboratory (DL) session. These sessions meet
twice a week and will contribute a large amount to the course, so it is important that you
attend these. During certain sessions you will perform experiments, while during others you
will work problems. These DL meetings contribute 25% to your grade, and are manditory!

Important! Drop Date Information
The deadline to drop without a W is the last day of Week 2 (of the semester), which
is Sunday, September 9th for Fall 2012. If you must drop a course, drop before the
specified deadline for dropping a class without a grade of ”W.” Dropping after Week 2 will
result in a W on your transcript. Effective July 1, 2012 students will only have 3 attempts
to pass a class. If a student gets a ”W” or grade of ”D”, ”F”, I, or ”NP” in a class, that
will count as an attempt. A students past record of course attempts district wide will also
be considered. Therefore, before the end of Week 2 you should carefully consider if you can
reasonably manage this course with the other factors in your life (e.g. work, family, course
load). If you think you will not be able to complete this course with a C or better, drop by
Sunday, September 9th. If you have any questions, please don’t hesitate to talk to me. You
may also see a counselor in the Counseling Center in AD 108.
