9/26/2013 I have converted all the problem solution
videos to H.264 MP4 format and uploaded all the
solutions to YouTube. I added links to the
YouTube playlist on the solutions pages of this web
8/23/2012 Reformatted SAC102 video solutions to H.264
8/28/08 Minor corrections of typos to Volume
I. New version is cbphysicsIA18.
3/24/08 Corrected some typos in the 2nd Semester SAC
problems. The current version is of the problems
document is SACProblemsIIa14.
3/12/08 Correction to page 188 of Volume I Chapter
21: Changed amplitude to "square of amplitude".
New version of Volume II is cbPhysicsIIb24.
3/01/08 Removed the circle from each of the integral
signs for the magnetic flux through a loop in Chapter
18 of Volume II. New version of Volume II is
2/28/08 Added computer algebra section to off-site
2/21/08 Corrected solution to SAC215-4. Many
thanks to Christopher Benoit.
1/30/08 Edited solutions dealing with electric
potential to effect change of using phi instead of V
for electric potential in 2nd semester SAC
1/14/08 Updated the 2nd semester formula
sheet accessible from the 2nd Semester
1/9/08 Volume II of book: Corrected some minor
typos. Added "one kind of charge"
footnote--thanks to John Denker for his insights on
that. Changed notation so that phi (instead of
V) represents electric potential. Am
still using V for electric potential difference.
So, V = Delta phi.
12/2/07 Corrected solution to SAC134-3
11/18/07 Added solution to SAC131-6.
11/17/07 Minor change to problem statement for
SAC132-6. Replaced the soltution that had been
posted for SAC132-6 with the actual solution to
9/3/07 Correction to solution to SAC103-4.
(Added "reference level.")
8/19/07 Fine-tuned the 1st semester SAC
problems. Avoided calling a variable a function,
made all force variable names F_subscript.
Changed the problem involving the Beck Centripetal
Force apparatus to make the problem a statics
problem. The document is now named
8/15/07 I made a lot of minor edits to Volume I, and
changed the notation for forces such that every force
is represented by an F with a subscript. I also
changed the wording to reflect something that John
Denker reminded me of on phys-l, namely that in an
expression such as v= v_0+at, v is not a function of
t, rather, t and v are both variables and v is what
you get when you evaluate a function, e.g. if you call
the function g, v=g(t)= v_0+at. This
version of Volume I of the book is the one available
at LuLu where it is called the green edition.
8/06/07 Added Data Analysis and Uncertainty
Calculations section to the Offsite Resources page.
8/04/07 On the Off-Site Resources web page: removed
dead links to The College Physics Mathematics
Pretest of H.T. Hudson and T.L. O'Kuma.
Added link to textbookrevolution.org. I had that
link on the Off-Site Resources page before but the
site vanished from the internet for awhile--it is
6/9/07 Corrected error in example 4-1 on page
23 of Volume I. I had substituted the wrong
value for m1. Many thanks to Kyle
Markham for pointing out this mistake.
6/8/07 Added information on what students are
expected to turn in for each of the SAC problems that
students are expected to solve using numerical methods
on a spreadsheet.
6/7/07 Changed drop distance for problem SAC106A-4
and changed "acceleration" to "angular acceleration"
in problem SAC117-6.
4/22/07 In Volume II of the book, I corrected
the equations in the discussion of Gauss's Law for the
magnetic field--where I should have had
an infinitesimal area element I had an infinitesimal
length element. Page 322, changed "distance" to
"square of the distance" in writing about r^2.
(Many thanks to Alex Macomber for pointing
out the latter error.) The new version of
Volume II is cbPhysicsIIb21.
4/22/07 In Volume II of book: The page
break between pages 287 and 288 occurred at a bad
spot. I fixed that. Changed "spherical" to
"closed" in characterizing an egg-shaped surface
on page 297. On page 302, removed note about
depicted Gaussian surface looking like a circle since
diagram has been improved to make it look like a
spherical shell. The new version of Volume II is
4/14/07 Edited ray tracing diagram problem
statements in SAC II problems to specify use
of 1:1 scale. Made minor cosmetic edits to
other SAC II problem statements as well.
New version is SACProblemsIIa10.
4/13/07 Corrected wavelength value for "blue"
light on page 239. (Thanks to Tom Dahlberg and
4/8/07 The textbookrevolution web site is being
moved to a new host. For now, the link is dead
so I removed it from the cbphysics "What's New" web
3/31/07 In Volume II, made some minor
edits on page 238, made page number correction to page
205 (thanks to Katherine Thibodeau), and (thanks to
Brendan Sweeny) added page headers on pages in chapter
22 that were missing them. New version of Volume
II is cbphysicsIIb19.
3/25/07 SAC problem 223-3 became 223a-4 and I
created a new SAC problem 223-3. I posted a
solution to the latter and renamed the solution file
sac223n3.asf to sac223an4.asf and bundled the
latter with the rest of the sac223a solutions.
The new version of the 2nd semester problem set is
3/10/07 Made following edits to volume 2:
(3rd to last line): Change "from which the extend"
to "from which they extend"
last sentence: change "decreasing" to "increasing"
Change "Source" to "source"
Many thanks to Amanda Chatterton, Alex Macomber, and
New version of volume 2 is cbphysicsIIb17.
Also, have finished adding quizzes to Calculus-Based
Physics II Learners Moodle course.
3/2/07 Refined SAC128 problem 4. The new
version of the 2nd semester SAC Problems is
2/25/07 Added solution to SAC215-4 to 2nd Semester
Solutions. Corrected subscript on page 20
(thanks to Amanda Chatterton) and removed extra
word from chapter 17 (thanks to Alex Macomber) of
Volume II. New version is cbphysicsIIb16.
2/17/07 Correction to problem statement for
SAC212-3. New version of SAC Problems is
2/12/07 Changed seat of EMF values in SAC211-2 and
211-3 back to original values to conform with posted
solutions. New version of SAC Problems is
1/28/07 Minor change to SAC 205-2 solution (put arrow
over symbol used to represent final velocity).
1/27/07 Minor changes to 2nd semester formula
sheet--new version is formulaIIa3.
12/31/06 Published cbphysicsIIb15 to Lulu.com .
12/31/06 Minor changes to Volume II--new version is
12/30/06 Volume II: Shortened chapters 18, 19, 20,
and 22 and made some cosmetic changes. The new version
12/22/06 Dr. David Banach of the Saint Anselm College
Philosophy Department set up a cbphysics Moodle server
on the Linux host he runs out of his home. I
have started setting up Moodle courses using the
resources at this site. The Moodle courses
currently under construction are at www.cbphysics.com/moodle
12/21/06 Over the last 3 months I have built up the
solutions to 1st semester SAC physics problems.
In particular, I have added 28 new screen capture
movie solutions. In some cases these were used
to replace old screen capture movie solutions and old
scanned pencil on paper solutions; in other cases they
are solutions to problems for which no solution had
previously been posted. I have also made some
fairly minor alterations to the 1st semester problems
sets--mostly minor edits to individual problems but I
found one problem statement that was in the wrong set;
I replaced it with a new problem and made it a "new"
last problem in the existing set to which it
belonged--where it should have been in the first
10/22/06 Minor edits to the 1st semester SAC
problems. New version is SACproblemsIa5. I
have added several solutions to 1st Semester
Downloads / Solutions to SAC Problems.
9/09/06 Volume I p29:changed "no transfer of
momentum" to "no transfer of angular momentum."
New vers: cbphysicsIa14.
9/03/06 Added the Merry-Go-Round video to the 1st
9/03/06 Minor edits have been done to chapters 1-4 of
volume I since the last update (current version is
cbphysicsIa13). The solutions to 1st semester
SAC problems have been updated. In particular,
the WinCam exe files have been replaced with ASF
files. The WinCam movies can now be viewed under
the Mac and Linux operating systems. (They can
still be viewed under Windows as well.) The
QuickTime and avi 1st semester solution files have
been replaced (to reduce file size improve
8/23/06 Changed avgWithErr and gaussEP to allow users
to format rows, columns and cells without having to
turn protection off. Current versions are
avgWithErrA2.xls and gauseEPv3.xls .
8/22/06 Made improvements to the average with error
spreadsheet and the Gaussian error propagation
spreadsheet based on suggestions by Kathleen Shartzer,
Laboratory Instructor at Saint Anselm College.
The biggest change was to protect some cells to
prevent accidental changing of values in them.
(It is easy for the user to remove protection:
Tools--Protection--Unprotect Worksheet.) Current
versions are avgWithErrA2.xls and gaussEPv3.xls .
8/20/06 Updated the Off-Site Resources web
page. Added links to Donald Simanek's Physics
Abused web page and the NIST web site.
8/19/06 Replaced the Gaussian error propagation
spreadsheets with a single spreadsheet
gaussEPv2.xls.zip good for 1 to 6 variables. Added
Average with Error spreadsheet
AvgWithErrA1.xls to the math resources web page.
It is for calculating the mean and standard deviation
of a set of values entered by the user.
8/18/06 Posted revised versions of error propagation
spreadsheets. 1varErrPropA2.xls to 6varErrPropA2.xls .
8/17/06 Posted revised versions of error propagation
spreadsheets. 1varErrPropA1.xls to 6varErrPropA1.xls .
8/14/06 Added missing section break between chapters
5 and 6 of volume I and republished to LuLu.com.
New version is cbphysicsIa12.
8/10/06 Added links to error propagation
spreadsheets to the math resources web page.
Each spreadsheet is used to find the mean and standard
deviation of a quantity that is a function of other
quantities for which the means and standard deviations
are known. A Monte Carlo method is
used to generate a column of 1000 values
corresponding to a Gaussian distribution for each
argument of the function and histogram of each set of
1000 values is displayed. The values are used to
calculate 1000 values of the function and a
statistical analysis of that set of values is done to
determine a mean and standard deviation. A
histogram of the 1000 values of the function is also
8/8/06 The screen capture with audio physics problem
solution videos for the first semester have been
converted to asf format (as opposed to exe
format). Now students can watch (and listen to)
the movies using operating systems other than WindowsTM.
I replace the old wmv and mov files with scans of
paper solutions because of the low quality and large
file size of the wmv and mov movies. This and
the conversions greatly reduced the overall size of
the 1st semester solutions package.
8/8/06 Minor edits to volume 1. (p28:emboldened
decimal point in "32.0"; p90: inserted comma after
"chains"; p91: "string" to "rope" in 2 places; p99:
subscript spacing in F_x.) New version is
8/3/06 Wherever, in volume II, I had written about
the flow of current, I replaced such
text with the "flow of charge," or, as in "the
direction of the flow of current," I struck "flow of"
so that, for instance, the example given would read
the "direction of the current." (Charge
flows. Current does not.) The new version
of volume 2 is cbphysicsIIb14.
7/30/06 Published current version of volume I
(cbphysicsIa10) to LuLu with a light blue cover--I
called it the blue edition.
7/29/06 Many thanks to Dr. Leigh Palmer, Prof.
Emeritus, Simon Fraser University, who pointed out
that my statement (in chapter 23) that the principle
of conservation of energy is the central, most
important, concept in physics was "over the
top." I agree! I added "in the opinion of
the author" to the sentence. The new version of
volume 1 is cbphysicsIa10.
7/21/06 Minor edits to chapters 20-34,36,37 of
volume 1. Changes to chapter 35. New
version of volume 1 is cbphysicsIa9.
7/16/06 Minor edits to chapters 3-19 of volume
1. New version of volume 1 is cbphysicsIa8.
7/9/06 Minor edits to volume 1, mostly to chapter
2. New version of volume 1 is cbphysicsIa7.
7/1/06 Added question sets for chapters 27, 28, and
29 to the 2nd semester class questions. The
current versions of the files containing the second
semester class questions are:
ClassQuestionsIIa5.pdf and ClassQuestionsIIa5.ppt.zip
6/8/06 Added links to Physics Documents by John S.
Denker and the PHYS-L listserve to the Offsite
resources page. Added links to the The College
Physics Mathematics Pretest of H.T. Hudson and T.L.
6/4/06 Fixed a link error pointed out to me by Eric
Ostlund. My add3vectors.xls link on the Math
Resources page was pointing to add2vectors.xls by
mistake. It now points to add3vectors.xls as
intended. This is the first mistake pointed out
to me by someone from the general public and I am most
grateful to Eric Ostlund for his random act of
6/3/06 Made numerous edits, mostly cosmetic, to
the 1st-semester SAC Problems. The current
versions of the files containing them are:
SACprobsIa2.pdf and SACprobsIa2.doc.zip .
6/2/06 Added the pre-calculus math videos
and the calculus ScreenCam movies to 1st Semester
Downloads under Math Resources. Added links to
add2vectors and add3vectors spreadsheets to the Math
Resources web page.
5/29/06 Made numerous edits, mostly cosmetic, to
the second-semester class questions. The current
versions of the files containing them are:
ClassQuestionsIIa4.pdf and ClassQuestionsIIa4.ppt.zip
5/26/06 Moved the math resource links that were on
the 1st Semester Downloads page to a separate
Math Resources page and, on the 1st semester downloads
page, I replaced the links to individual math
resources with a link to that one page.
5/21/06 Made numerous edits, mostly cosmetic, to the
first semester class questions. The current versions
of the files containing them are:
ClassQuestionsIa3.pdf and ClassQuestionsIa3.ppt.zip .
5/16/06 I zipped up all the 2nd semester
class questions and posted the zip file and a pdf
file of all the 2nd semester class questions to the
2nd semester downloads page. I removed the
html page with the links to the individual 2nd
semester class question files.
5/11/06 Changed the artwork in the Gauss's Law
chapters (Calculus-Based Physics II chapters 35 and
36) to give 3D Gaussian surfaces, electric fields, and
charge distributions a 3D look. The (old) 2D look
caused some confusion about the nature of a closed
surface. New version of volume 2 is
5/6/06 The diagrams in problem SAC 211-5 looked like
double exposures in the pdf version of the 2nd
Semester SAC Problems. I made changes to the WordTM
version of the 2nd Semester SAC problems and the 2nd
Semester SAC problems in Random Order and generated
the corresponding pdf files. All the new versions have
now been uploaded to this site.
5/5/06 Corrected a typographical error found by
Katherine Coit and one found by Cristian Costescu.
Both errors were near the end of Calculus-Based
Physics II (roughly chapter 32 and chapter 36). At the
time of this post, Katherine and Cristian are students
in my Classical Physics course. The current version of
volume II is cbphysicsIIb12. Added 2nd semester class
questions for ch 34 and 37.
4/29/06 Fixed link to 2nd semester solutions on the
Downloads II page. (It was set to the 1st semester
4/28/06 Added a misconception preamble to Volume II
Chapter 32 (Gauss's Law). Added some 3D effects to
diagrams in chapter 32 and text emphasis that Gaussian
surfaces enclose 3D volumes of space. The new version
of volume 2 is cbphysicsIIb11 (replacing
cbphysicsIIb10). Added second semester lecture 35
4/23/06 On the "Offsite Resources" web page: Added a
link to the University of Minnesota Physics Education
Research and Development web page.
4/22/06 Added more 2nd semester class questions. I
also added some more 1st semester class questions. The
new compressed file ClassQuestionsIa2.ppt.zip includes
all the old 1st semester class questions as well as
the new ones. Added the "About the Book" page to the
web site and posted the "Why I Wrote the Book and Why
I Released it for Free" document. Eliminated
the sample WinCamTM (executable files)
would no longer download and play. Instead, upon
clicking on one of them, one would get a file not
found message despite the fact that the file was
there. I assume this is the result of a recent
security update to Microsoft Internet ExplorerTM.
I compressed the sample WinCamTM files. Now
the user has to download and unzip a WinCamTM
executable file to watch a WinCamTM movie.
I revised the instructions accordingly.
4/15/06 Uploaded an updated version of the 2nd
semester SAC problems. The update represents many
minor edits made during the Spring 2006 semester. Most
of them were cosmetic but there were some corrections,
and, a couple of new problems were added as well.
Embedded fonts other than common system fonts in the
textbook word files so that folks can edit the WordTM
files without having to install the physics and
GoLoSymbols fonts. Eliminated some of the text from
the home page.
4/08/06 Added more 2nd semester class questions.
4/2/06 Added the link to Donald Simanek's physics
documents and links to my list of offsite research.
What a resource!
3/31/06 Added more 2nd semester class questions and I
embedded fonts in all the 2nd semester class
questions. I created a new zip file
ClassQuestionsIIa2.ppt.zip of the class question files
(with fonts embedded), but, I did not create a new pdf
version of the class questions--I plan to wait until
the end of the semester to do that. I embedded fonts
in the 1st semester class questions too. The files in
ClassQuestionsIa1.ppt.zip now include the fonts.
3/24/06 Added more 2nd semester class questions.
3/18/06 Starting with cbphysicsIIb9:
Added equation numbers to 3 equations in chapter 19
Induction, Transformers, and Generators.
On page 185, changed "The total magnetic at point P
field" to "The total magnetic field at point P" to
correct word order error. (Thank you Jamie Vaughn!)
On page 200: put the E in the equation relating the
intensity of light to the amplitude of the electric
field oscillations in italics. (It was in the normal
On page 13, corrected spelling of Calculus and put
book title "Calculus-Based Physics" in italics.
On page 211, two lines above diagram, changed "the
the" to "the." (Thank you Cristian Costescu!)
Resulting version is cbphysicsIIb10.
3/10/06 Made minor edits to chapters 30-37 of
Calculus-Based Physics II (now cbphysicsIIb9).
3/8/06 Made minor edits to chapters 28-37 of
Calculus-Based Physics II (now cbphysicsIIb8). I
included some of the steps that I had intentionally
left out of the solution to the second example problem
in chapter 32. I decided to include them so that the
reader would not have to flip back to chapter 30 to
understand the solution; and; in order to avoid
conveying the impression that it would be okay for a
student, in solving a homework problem, to start with
an intermediate result from a sample problem rather
than to start from "first principles." This made
chapter 32 one page longer than it was. In chapter 30,
in several cases, I made a copy of a diagram or
equation that was on one page, on the next page, to
reduce the amount of flip-back that the reader had to
do in referring back to earlier diagrams and
equations. This lengthened chapter 30 by one page. I
also removed the equation numbers from the steps in
the solutions to the example problems in chapter 30.
In chapter 37 I corrected some glaring errors in the
tables of the very last page of the book.
3/4/06 Made minor edits to chapters 25-27 of
Calculus-Based Physics II (now cbphysicsIIb7).
3/3/06 Added more 2nd semester class questions.
2/25/06 Made minor edits to chapter 11 (thanks to
Katharine Coit and Kevin Bersell), chapter 17 (thanks
to Cristian Costescu), and chapters 22-24 of
Calculus-Based Physics II (now cbphysicsIIb6).
2/18/06 Made minor edits to chapters 19-21 of
Calculus-Based Physics II (now cbphysicsIIb5).
2/10/06 Made minor edits to Calculus-Based Physics I
including the addition of information on power units
in chapter 25 as recommended by Katharine Coit and
Kevin Bersell, students in my calculus-based physics
1/27/06 Created a new page entitled "Additional Class
Questions" under 2nd Semester Downloads and started
posting the new class question power point slides that
I am creating for the current semester to that page.
Any old question sets that I revise this semester will
be posted there too (so there will probably be some
redundancy with the question sets in the zip file).
The plan is to incorporate the new question sets in
the pdf and zip files at the end of this semester and
remove the "Additional Class Questions" page at that
1/17/06 Combined chapters 32 and 33 into 1 chapter
thus reducing the number of chapters to 37.
1/8/06 Replaced cbphysicsIIa1 (Volume 2 of the book)
with cbphysicsIb1. Added chapter 38. Shortened chapter
Made minor corrections to chapter 1.
12/31/05 Made cbphysicsIIb1 (Calculus-Based
Physics II) available as a paperback black-and-white
book at lulu.com at the cost of production, namely
$11.44, which is less than what it would cost me to
make a photocopy of the book.
12/31/05 Made cbphysicsIa5 (Calculus-Based
Physics I) available as a paperback black-and-white
book at lulu.com at the cost of production, namely
$9.88, which is less than what it would cost me to
make a photocopy of the book.
12/31/05 Replaced cbphysicsIa4 (Volume 1 of the book)
with cbphysicsIa5. (Minor corrections.)
12/27/05 Added 2nd-semester Class Questions
(Microsoft Power PointTM slides and pdf
version of same) to 2nd Semester Downloads.
12/23/05 Added 1st-semester Class Questions
(Microsoft PowerPointTM slides and pdf
version of same) to 1st Semester Downloads.
12/11/05 Replaced cbphysicsIa3 (Volume 1 of the book)
with cbphysicsIa4. (Eliminated 1 erratum. It was
pointed out to me by Jamie Vaughn, a student in my
calculus-based physics course.) To update your
copy of cbphysicsIa3 to cbphysicaIa4, replace pages 1
12/09/05 Replaced cbphysicsIa2 (Volume 1 of the book)
with cbphysicsIa3. (Eliminated 4 errata, 3 of which
pointed out to me by Cristian Costescu, a student in
my calculus-based physics course.) To update your hard
copy of cbphysicsIa2 to cbphysicaIa3, replace pages 1,
80, and 264 from cbphysicsIa2
with pages 1, 80, and 264, respectively, from
12/08/05 Added links to professor Hunt's Physics
Tutorials and Socratic Problem Solutions.
12/08/05 Added pdf "printouts" of the on-line
Blackboard quizzes to both 1st semester and 2nd
11/26/05 Added fonts and 1st semester
formula sheet to 1st semester downloads.
11/25/05 Added "What's New."
11/25/05 Replaced cbphysicsIa1 (Volume 1 of the book)
with cbphysicsIa2. cbphysicsIa2 implements an
20-30 minor edits correcting
errors (10 of which were pointed out to me by my
students!) uncovered through use of the book during
the Fall 2005
semester at Saint Anselm College. These corrections
would be listed as errata in a traditionally-published
10/25/05 Added Math Handouts to 1st semester
11/24/05 Added Solutions to 2nd Semester
11/20/05 Added Off-Site Resources page.
11/14/05 Released Calculus-Based Physics
(version a revision 1) and ancillary materials under
