Unit 03 Homework Assignment Physics Key Equations
Please note: starting in the fall of 2014, I will no longer be teaching Chemistry, so while these resources will remain available on my blog, they will not be updated until I teach Chemistry again. Feel free to email me if you have any questions at ke_ccarman *at* kentschools *dot* net!
I’ve created two kinds of chemistry practice quizzes – interactive quizzes and standard quizzes. The interactive quizzes are good for “drill and kill” review to get a concept down, and for the general public. The standard quizzes are formatted to be similar to the ones I give in CP Chemistry at Roosevelt High School, and would be best for my students who are preparing for a specific quiz in class.
Interactive Quizzes
CP Chemistry Practice Quizzes
These are my standard practice quizzes for CP Chemistry at Roosevelt High School. They are based on the same learning targets as the actual quizzes, so you should use these to study before we take the real thing in class. Just click on the Quiz name to start! If you still want to use the PDF version that’s exactly like the paper version I use in class, click on the PDF link instead.

(Notice that Webassign randomizes the numbers used in each problem. The short answer keys provided by the webassign are based on the chosen number listed in that question. While the detailed solution method is demonstrated using the numbers chosen in our textbook. It is your job to understand the HW solution and be able to apply the same method to different numbers).

Lecture: MWF 11:10noon, SCI 101
Instructor: Dr. Weining Man Office: TH 316 phone: 4153382731

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.

For example: Tom Jones with last 4 digits of SFSU id of 1234 will have username: jones1234 and initial pw: 1234
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.
