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 on-line homework. You can also use James Walker, Physics, 4th edition, (Pearson/Prentice-Hall, 2009) or James Walker, Physics, 3rd edition, to save some money (Pearson/Prentice-Hall, 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 cell-phone, make noise, walk in-out, 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 (W9:35-10:50 T-P4), 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 (5-6 written ones and many clicker-based 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 examhttp://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.

Final Exam: 10:45-1:15    SCI 101

 

Checklist of what you should do: (12-14 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 make-up 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)

Reading text before lectures: (1-2hr each, 3+ times per week) 

                                          _ Su 8-10PM_______________         _T 9-10PM____________           __Th 9-10PM___________

Review Lecture notes:  (0.5-1 hr each time, 3+ times per week)              

                                          _ M 7PM  _____________     _W 7 PM______________             __Sa 1PM_____________

Do HW:  (1-4hrs, attempt HW 3+ times a week)

                                          _ M 8-10PM  _____________            _W 8-11PM____________         __Sa 2-6PM_____________

Review HW solutions:(0.5-2 hrs)              

 M 7PM  _____________              _Sa 1  PM____________           _Redo hard HW questions on Sun

Attend SCI 111 or office hours

(Bring all questions and have answered right away. Do not wait till falling behind.):   M 7PM  _____________                 

 

How to make homework easier:

·         Start to attempt HW as early as possible. To finish before the due date, allow 2-4 days (4-8 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 problem-solving 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 help--but 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!
