Quick reading notes
These notes are ones that I have written when I taught 7B (SS2, 2006). The
order is somewhat different from the current order physics 7 is taught,
and this is deliberate. There is no way that you can understand torque
(for example) without doing force diagrams
first, and so this is
the order presented in these notes.
Currently, for whatever reason, the order of physics 7B is jumbled. This
may mean you have to read a couple of these notes to get enough background
to understand what you are reading. The effort is worth it.
These notes are a page or two long. They are intended for brief reviews of concepts,
and are light on examples. More through examples and notes are developed below.
Good luck in 7B!
-
Introduction to momentum
- Introduction to forces
- More on different
types of forces; an introduction to different types of graphs (a vs
t, v
vs t and displacement vs t)
- Using Newton's
second
law "backwards": i.e. see the motion and then infer what
forces must be acting. Important example: Circular motion.
- Introduction to circular
motion and the right hand rule.
- Introduction to angular
momentum
- Introduction to
torque
I also have two reviews of physics 7B available:
- A brief review. Hits most of the
main topics covered in the course, and is nice and short.
- A more detailed review. Has a few
more worked examples, and "clicker" questions but is much
longer.
Detailed notes with worked examples
These examples go into more depth than the quick reading presented above. They
contain worked examples, but are a lot longer. Eventually you should be able to
download them chapter by chapter
or as an entire set.

Physics 7 and the MCAT
Physics 7 is not intended to be a complete preperation for the MCAT. It
does not cover all the material the MCAT does. For a list of material the
MCAT covers, and which Physics 7 series course (if any) is contained in
Physics 7 and the MCAT.
Lectures
Note that the order of material has changed: as of Fall 2007 fluids have come
first, followed by mechanics. Therefore it may be easiest to start at lecture 6
-8, then 1-5 and finally lectures 9 and 10 in the new syllabus.
- Lecture 1: Vectors, velocity and speed
- Lecture 2: Momentum and force
- Lecture 3: Momentum and circular motion
- Lecture 4: Rotational motion
- Lecture 5: Rotational motion, extended
force diagrams.
- Lecture 6: Beginning fluids, energy in
fluids.
- Lecture 7: More fluid examples,
electrical circuits.
- Lecture 8: End of lecture 7.
- Lecture 9: Exponential decay, SHM
- Lecture 10: Quick review (not the same as
the long review)
"Exit quizzes"
In summer session II 2006, Jamison Galloway and I created a series of
5-10 minute quizzes. The idea was that after a DL students should be
given a quiz relating directly to that material so that they could assess
for themselves if they got the main ideas in that lab
before
it counted for credit (i.e. before the weekly quiz). To make it easy for the
TAs to grade, the quiz was done collectively for each group.
The exit quizzes are no longer implemented, but they are still an excellent
source of problems. They are reposted by DL below. Note that the order of
material in the course has changed, so some of the exit quizzes may be out of
order.
No answers have been created but these are good questions for trying out and
taking to office hours.
Old quizzes
In many cases, the rubric contains a solution. In cases where the rubric does
not contain the full solution an additional "solution" link has
been added.
Other helpful links
Some other graduate students have been kind enough to devote their time to
help you survive physics 7B. Please check out:
In addition you should check out the following two links by Dan Styer that
addresses the frequently asked questions "how do I study for quizzes?"
or "how do I get the most out of the homework" very eloquently in
these articles:
Check out the
camera obscura in the aboretum before it disappears at the end of January 2008! Located
by Spafford Lake. (Note: A camera obsucra is technically a pin-hole camera. This viewer has a lens, as you
can tell from the distorsion of the images. The apature is also too large to form good images from a pinhole
camera.) At the very least see the
Room with a View on
the Davis wiki page!
FNTs
Find the
FNTs
here. Solutions will be posted
after the due date for the FNTs. Note that these solutions were written a while ago, and problems may change.
- FNT 1 Vectors, addition of vectors
- FNT 2
Introduces impulse, the difference between elastic and inelastic collisions
- FNT 3 Introduces force digrams, and
the importance of contact time
- FNT 4 More on momentum
conservation
- FNT 5 Angular momentum and
torques
- FNT 6 The bicep and merry-go-round
problem (to be completed....)
- FNT 7: No solution set, answers vary depending on choices you
make. It just has to be consistent.
- FNT 8: No solutions at this time (this FNT was on graphical
techniques).
- FNT 9 An introduction to pipes
- FNT 10 The fluid transport equation
(Bernoulli's equation).
- FNT 11 More on fluid flow
and dissipation
- FNT 12 Looking at power
dissipated by christmas lights.
- FNT 13 A continuation of the
ideas presented in FNT 12
- FNT 14 Heat, electrical and fluid
fluxes
- FNT 15 Expontential decay
