Welcome to Phys 111 General Physics I: Mechanics, fluid, sound, and heat using
algebra and trigonometry. This course must be taken concurrently with PHYS 112, the lab session. PHYS 112 starts to meet during the
second week of class.
Text: (required) James Walker, Physics, Custom Edition for SFSU (Pearson Custom,
2009). PHYS111 will cover the 18 chapters Volume 1, but you may want to get the
combined volume 1+2 book if you will be taking Physics 121. The bookstore has a
“bundle” with the textbook, lab manual, and a WebAssign access
code for the online homework. You can also use James Walker, Physics, 4th
edition, (Pearson/PrenticeHall, 2009) or James Walker, Physics, 3rd
edition, to save some money (Pearson/PrenticeHall, 2007).
Recommended supplements: You may like the Study Guide, Vol.
1, by Walker; available at the bookstore.
Reading: Complete each reading assignment before the
class during which the topic is discussed, otherwise the lectures will be too
hard and too quick to follow. Repeat the reading, especially the chapter
summary, before doing homework.
Class attendances: Attendance and participation in classroom
activities are extremely important. Bring your calculator to class. Be on
time for class. Unannounced quizzes based on homework or reading
assignments can be given. We focus on understanding concepts, equations,
applications and “why” in the lectures. Keep your mind active.
It’s impossible to learn physics by memorizing facts and following steps to
plug numbers into equations. To understand it is the most crucial thing.
Please do not use cellphone, make noise, walk inout, or do other things
to disturb lectures.
Homework: There will be a homework assignment due before each
lecture, two to three times a week. These will be entirely on
the WebAssign system. Once HW due date passes, the system will not accept answers. No
HW extensions. Homework solutions will be posted online every
week. To do homework actively is the most effective step to learn
physics. It is very important! Group study is encouraged, but make
sure to work out your own problems independently after
discussing with your friends or tutors. If you get fish (the homework
solutions) without really learn fishing (to solve similar problem alone), you
will do poorly in quizzes and exams. If you pass the Math readiness exam,
your Webassign account will be ready by Wed in the
first week.

Update your frequent
checking email address in your webassign account, so that you will receive future
announcements about exams on time. Read the instructions and practice
submitting answers with correct numerical format and formula format, in the
first assignment. Fee: (~$20 semester), you can pay any time during the first
two weeks. The code can be bought through Webassign website
or together with textbook in the bookstore.
Help Session: Not many sample questions can be solved step by
step during the PHYS 111 lectures, due to the fact that we cover more than
one chapter each week. Make sure that you attend my weekly help session, where
I will work through calculation problems step by step and help you with
homework. Please sign
up for SCI 111 (W9:3510:50 TP4), if you need more problem solving guide and homework help. Every week, there are a few more help sessions offered by PHYS
112 instructors to help you with PHYS 111 homework. Don’t count on the very limited
lecture hours for HW and problem solving help.
Exams: 2 midterms and a comprehensive final. Quizzes (56 written
ones and many clickerbased in class quick quizzes)
Missing exam will receive zero point, unless previously discussed.
Academic dishonesty: Students are expected to perform their own
work on all assignments in the course. Dishonesty on an exam, quiz, or homework
will result in a grade of zero for that assignment, or even a failing grade for
the course.
Grading: The final score will be based on the homework and exam
scores as indicated below:
Final Exam
30% Midterms
40% (20% each) Quizzes and
clickers (drop 1) 15% Homework
(drop 2) 15%
Final letter
grade: 90
and up : A: 75
and up
: B; 60
and
up: C; 50
and up : D.
I will not curve. I do give bonus points for
your real effort. I wish everyone to
do very well and get B or better (75 out of 100 or better). I do not limit the
number of As. Extra bonus points can be given to students who finish bonus
assignments actively. (The class average of last semester was B
25% students got As, and another 20% failed or
dropped.).
Prerequisites: MATH
109 or equivalent. You
need a passing grade on the Physics Dept. Math Entrance readiness exam, http://www.physics.sfsu.edu/Academics/Readiness.html (about algebra, geometry, trigonometry),
which will be administered by the department. (Make sure to
take the exam if you want to add). If you fail the entrance exam,
you will be dropped from both PHYS 111 and PHYS 112.

Checklist of what you
should do: (1214 hours a week is expected in order to understand 18 chapters
in 16 weeks.)
· Read
the text before each lecture, otherwise lectures will definitely be
too quick and too hard to follow.
· Understand all
concepts, equations and “why” in lectures. You will get lost if you
just memorize facts or plug numbers.
· Don’t
miss class. To makeup takes 3 times of lecture
time. Carefully review notes if you have an
unavoidable absence.
· Study
in groups and help each other, but do not simply give or ask for
answers.
· Finish HW independently after discussions. Make sure that you
understand everything by yourself. Mark those hard ones.
· Request
keys on Webassign. Review HW
solutions posted after due date. Redo all the hard ones before quizzes
and exams.
· Go
to at least one help session every week. PHYS 111 lectures are not
long enough for showing many step by step examples.
· Improve
your math skills. Otherwise, you will have a hard time
solving equations for physical quantities.
· Keep
up with the materials as it is covered. New sessions build on the
previous. It is much harder to catch up once fall behind.
Please fill the blanks with reserved time slots
for PHYS 111. (A good sample is suggested
below)

How to make homework easier:
· Start to attempt HW as early as possible.
To finish before the due date, allow 24 days (48 hours total) for
reviewing, practicing, and reading new chapters. It’s impossible to finish HW
the night before due date. The number of
allowed attempts on calculation problems are not limited 48 hours before due
date.
· Review
the text, chapter summary, lecture notes, and problemsolving steps
on notes and textbooks..
· Understand
your questions before plugging numbers into equations.
· Start the
problem by drawing a diagram. Explain your solution in words.
· If homework
looks hard, first try to solve the sample problems on the book and lecture
notes without peeking.
· Pay
attention to units. Check results and order of magnitude to make sure they are
reasonable. Pay attention to round off error.
· Get
helpbut only after trying the problems yourself. Discussions are
allowed and encouraged. But NEVER cheat! Offering or asking homework answers
completely destroy the precious learning opportunities.
Make sure that you sign up for the one unit
SCI111 and attend at least one help session per week, if you need problem
solving guide and homework help. Don’t count on the very limited lecture hours for HW help and
problem solving help.
* Students with medical
conditions or learning disabilities who need reasonable accommodations are
encouraged to contact me for necessary arrangements. The DPRC is available to
facilitate the process (dprc@sfsu.edu)
* This is one of the
classes that are “impacted” (more students wish to enroll than the spaces
available). Withdrawal will be permitted only if documentation of the “serious
and compelling” reasons is provided.
When deciding whether to withdraw from a class, please note that
university policy allows you to take the class only one more time.
Please visit my
website for updates, lecture notes, and HW solutions. http://www.physics.sfsu.edu/~wman/phy111.htm
Please keep an eye on
your webassign announcements and sfsu email accounts for
announcements.
Please
keep in touch and let me know how you are doing and how I can help. I am
looking forward to a fun and successful
semester. Let’s start the journey to the fun Physics
world. Enjoy!
