LECTURER: Sahana Moodakare Bheema, Instructional Asst TELEPHONE: 313-577-0209 E-MAIL: ba0757@wayne.edu (Please put PHY2130 in subject line) COURSE WEB PAGE: WSU Blackboard OFFICE HOURS: M and Th: 5:15 PM 6:00 PM at 170/171 OAK LABORATORY: PHY 2131 is the laboratory portion of PHY 2130. It is a co-requisite and, thus, is mandatory for you to be enrolled in both courses concurrently. However, laboratory is treated as a separate part of the course with its own grades and procedures which will be explained by your laboratory instructor. The experiments provide tangible demonstration and reinforcement of the ideas presented in this course. In addition, the laboratory is meant to show the importance of experiments in science. Your Laboratory Manual is to be purchased separately at the University Bookstore. For further details please inquire with Dr. Scott Payson at 313-577-3280. Lab sections of PHY 2131 will begin week of 14 September 2009 QUIZ SECTIONS: Quiz sections meet once per week and are important. They allow you to meet together in small groups to ask questions, discuss lecture material, discuss assigned practice problems, etc. The practice problems are intended to test your understanding of the course material. In the same way you must practice to become proficient at a sport or musical instrument, you must work problems in order to master basic physics. It is very important that you work out the solutions to each problem, and understand clearly the correct method of solution. It will be difficult to obtain a good grade in this course without making a conscientious effort to do all of the homework assignments. Quiz instructors, by using a few examples, are there to help students to understand the problems and to learn problem solving skills. However, they may not have time to do all the problems in details. It is student s responsibility to work on all the practice problems. In the quiz sections, particularly during (but not limited to) the weeks indicated by asterisks, you may be given short quizzes, which will have questions and problems similar to your homework assignments. Five best quizzes will be counted toward your final quiz score. You will have the opportunity to earn up to 10% of points towards your course grade for the performance of the quiz sections. No individual make-up quizzes will be given. 1

There will be three mid-term exams, consisting of multiple choice questions (no partial credit). You will drop the lowest of the three exam scores. There will be NO make-up exams. Repeat: THERE WILL BE NO MAKE-UP EXAMS. This is the reason you are allowed to drop one exam score. If you must miss the exam, that will have to be the one you drop. You MUST bring your Wayne State ID to the exam and present it to a proctor when you hand in the exam. No electronic devices (other than a calculator) are allowed in the room during the exam (no ipods, headphones, cell-phones, Blackberries, etc.) BONUS POINTS (ONLINE HOMEWORK): The WebAssign online testing system (http://webassign.net) provides online homework submission and grading. You will be asked to solve and submit for grading some additional problems each week for a maximum bonus 10% of your final score. I may give you additional extra-credit points using WebAssign. You are encouraged to do the problems in a timely fashion. For maximum flexibility, the online homework problems are due after each exam of related content materials (e.g. problems related to the first three chapters are due after the first midterm.) If you buy the book in store, it will include a WebAssign access card valid for two semesters. However, if you loose this card you need to purchase it through the internet. Your username and initial password are your six characters WSU ID (e.g. ab1234 ) and last name with first letter uppercase respectively. Please consult your WebAssign Student Guide for additional information. GRADING: Your course grade will be determined by your performance in three midterm Exams, Online Homework (bonus), Quiz Section results, and a Final Exam. The Final will cover the material presented during the entire semester. The overall course grade will be determined on the basis of the following distribution: Midterms drop lowest score of 3 50 points (25 X 2=50 points) Quiz section performance 10 points Final Exam 40 points Online Homework (bonus) 10 points Total 110 points (out of 100) The overall course grade will be determined on the basis of the following table: Grade Cumulated score Grade Cumulated score Grade Cumulated score A 91 100 B- 70 74 D+ 50 54 A- 85 90 C+ 65 69 D 45-49 B+ 80 84 C 60 64 D- 40-44 B 75-79 C- 55-59 F 0 39 2
ADDITIONAL STUDY HELP: If you have difficulty doing HW or lab work, or understanding some of the course material, you can get help from the Physics Resource Center, in room 172 Physics (the center will open in couple of weeks).

The things you must do to achieve your best results are amazingly clear and should not be unknown to you. Previous experience with many, many students has shown the following traits/habits seem to be common to most students who excel in the introductory physics course. 1. Get a book. Read it. Use it. There are LOTS of very good hints and ideas in the Preface. Most students do not read the Preface, but in it the authors have given you their best advice on how to use the text successfully. 2. Actually read the text (with a highlighter if you prefer). This is preferably done 5
before the class lecture, and if possible, afterward as well. 3. Put in the time. The text book recommends (and we agree) that you should be spending at least 2 hours outside of the class for every hour of lecture. This is at least 6 hours per week. 4. Practice, practice, practice. Do the quiz section assignments (before class), do the extra credit problems, do the suggested problems. You can watch Michael Jordan play basketball for 3 hours a day, every day, and you will never get better at basketball not unless you yourself put in the practice. 5. Strive for understanding. Many students feel if they just get the answer from a TA, or help center person, they have accomplished the task. This is incorrect. You have accomplished your task when you truly understand the problem, how to set it up, how to solve it, and what it is asking. Just completing the problem to get some random answer is not enough. 6. Come to the class. If you have a documented disability that requires accommodations, you will need to register with Student Disability Services for coordination of your academic accommodations. The Student Disability Services (SDS) office is located at 1600 David Adamany Undergraduate Library in the Student Academic Success Services department. SDS telephone number is 313-577-1851 or 313-577-3365 (TDD only). Once you have your accommodations in place, I will be glad to meet with you privately during my office hours to discuss your special needs. Student Disability Services mission is to assist the university in creating an accessible community where students with disabilities have an equal opportunity to fully participate in their educational experience at Wayne State University." 6
