This is a three credit course which must be taken concurrently with the one credit lab, Physics 2141. 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 2141 will not meet during the first two weeks of the course.

The goal is to give an introduction to physics based on algebra and trigonometry. Electricity, magnetism, and modern physics are covered.

Hour Exams(50%)
There will be three in class exams during the term and the scores of the best two will be used to determine grades. Exams will be closed book but students will be allowed one 8.5x11 inch page, both sides, of notes. This will be turned in along with your completed test. Make up exams are not given. You must bring your Wayne State ID to the exam and present it to the proctor when you hand in the exam. No electronic devices other than a calculator are allowed. Exams are about 20 multiple choice questions and there is one hour to do them.
Final Exam(35%)
The final is scheduled for 13:20-15:50 on 28 April. The exam is scheduled by the University; do not ask about taking it at any other time. Anyone missing the final will receive an I and must see the instructor as soon as possible to make it up. The final is comprehensive and is like a double length hour exam with about 1/3 from material covered after the third hour exam and the rest from the previous material.
This will be done via WebAssign. Either use the access you got with your text book or go to to sign up for the semester. It costs about $20. Once signed up look for my class. There are weekly REQUIRED assignments that will determine this portion of the your grade.
Extra Credit (10%)
Extra homework can be done in WebAssign. These are the BONUS assignments. Note that these problems are very much like what will be found on the exams.
Additional Problems
See below for additional problems that are associated with each chapter. Note that these problems are very much like what will be found on the exams, but include choices with the correct answershighlighted. These provide additional practice for exams.
Resource Center
For help on problems etc. visit the Physics Resource Center in room 172 Physics. It opens two weeks into the semester..
Quiz Sections
This where you should go to ask questions about homework problems, extra credit problems, and the additional problems. Instructors will not do the homework problems for you, but there are many similar problems in the book or among the additional problems that the instructors can help with.
There is no "curve". Please do not ask.

Students with Disabilities
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 (TTY: telecommunication device for the deaf; phone for hearing impaired students 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.
Tips for Succeeding in Introductory Physics
There is no “secret” to succeeding at Introductory Physics. 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. Come to class. At every university I have been associated with studies have been taken to find out what best predicts student success. Regular class attendance is the thing that is most associated with student success. Perhaps this is obvious, but many students do not show up and wonder why they are doing poorly.
  2. 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.
  3. Actually read the text (with a highlighter if you prefer). This is preferably done before the class lecture, and if possible, afterward as well. Make sure you read the “Master the Concepts” section at the end of each chapter – it is critical to summarizing what you’ve learned.
  4. 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. It is best to spend time both before class getting familar with the material, see above, and after class reviewing the material.
  5. Practice, practice, practice. Do the assigned homework, do the extra credit problems, do the additional problems, and do book 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.
  6. 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. Realize that we allow you to write down the formulas you will need, thus memorization is not terribly helpful.
  7. Attend your instructor’s office hours. This will be most effective if you bring your book and your homework problems and ask him/her to help you identify your “sticking points.” Open-ended statements like, “I don’t get any of it,” will not be helpful in this setting.
  8. Do a self-evaluation (and be honest). If you really want to know how you will do on the exam, give yourself an honest evaluation. Pick a few problems randomly from the text that you haven’t done before. A friend or family member can help with this. If you can solve it without any other help, you are ready. If you have no idea how to do it, you are not ready.
  9. Memorizing previously worked problems is NOT studying. Many students feel exam preparation should consist of just “looking over” old problems and old exams. That is incorrect. An exam will generally consist of new, unseen problems. While completely understanding the assigned problems is a good idea, your best strategy is to try to work as many new problems as possible (this is accomplished by practicing, as suggested above).
