(August 26, 2007) Course Materials General Information Schedule and Assignments Equation Sheet Handout on Optics (version August 19, 2007) (version August 19, 2007) (version August 26, 2007) (version August 26, 2007) Textbook and Webbased Homework System The text is University Physics, by Hugh D. Young, Roger Freedman and Lewis Ford, and published by Pearson Addison Wesley. You will need only volume 2. You also need access to the webbased homework system "Mastering Physics." The bookstore will sell a combined package (the books plus online access) for $122.85, using ISBN 0321500393. You can also buy the combined package with book and online access directly from the publisher at this link for $114.67. That price includes standard shipping (12 day Fedex). Dear Student: In Physics 21, you will be using MasteringPhysics, an online tutorial and homework companion to your textbook. What You Need: A valid email address A student access code (packaged with your text or available for purchase at http://www.masteringphysics.com/). The zip code for your school: 18015 A "Course ID": PHYSICS21F2007 (make sure to use all caps) A "Student ID": your LIN (nine digit Lehigh Identification Number) Welcome Albert Hickman (aphickman) Instructor message for Course PHYSICS21F2007 Physics 21, Lehigh University, Fall 2007 Course Instructor: Hickman Recitation Leaders: Belony, Kanofsky, Lyu, McGeehan, and Sweeney Information for Instructors Getting Started with MasteringPhysics New Features in this Release Young/Freedman 11eto12e EndofChapter Correlation Grid (MSExcel) Frequently Asked Questions (FAQ) Best Practices Tips for Preventing Cheating Physics 21 Fall, 2007 General Information Grading: Grades are based on the following scheme: First Exam (Oct. 4) Second Exam (Nov. 1) Five Quizzes Homework (on the web) Recitation leader's assessment Final Exam Total 100 100 50 50 50 200 550 Subject matter: Physics 21, Introductory Physics II, is a continuation of Physics 11. The general topics covered include electrostatics and magnetostatics, DC circuits, Maxwell's equations, waves, geometrical and physical optics. General Plan: Classes meet four times per week, Tuesday and Thursday in a large lecture (for 50 minutes) and Wednesday and Friday in a small recitation class. Homework assignments, which are done online, will be due before most lectures and will be discussed in the recitation the next day. Occasionally, homework will be due on a recitation day. There are two major exams during the semester, at 4:10 pm on Oct. 4 and Nov. 1. The final exam will be scheduled by the registrar. Textbook and Homework: The text is University Physics, by Young and Freedman, volume 2, 12th edition. The homework will handled by a webbased system called "Mastering Physics." Each student must obtain an access code (a 30 letter password) in order to register with the Mastering Physics website. The access code can be purchased separately or as part of a package with the textbook from the campus bookstore or from the publisher's web site. There is more information about "Mastering Physics" on the main class webpage and in other handouts. Obtaining Course Materials: Most "handouts" such as the reading assignments, schedule of lectures, and equation sheets must be downloaded from the course web page: www.lehigh.edu/~physics/21 Paper copies of these documents will not normally be distributed in class or recitation. It is the responsibility of each student to visit the course web page and obtain the appropriate documents. Quizzes: There will be five quizzes during the semester. They will be at the beginning of the recitation section on the dates announced in the schedule. No makeup quizzes will be given. Makeup Exams: Makeups will not be given for the hour exams. If a student misses an hour exam for a legitimate reason, a designated part of the final exam will be counted as the missed test. Final Exam: The date and time of the final exam are set by the Registrar and cannot be changed. Role of Recitation Leader: Each student's primary contact should be with his/her recitation leader. If you have questions or need help with an assignment, first ask your recitation leader. Each recitation leader will set his own office hours. Equation Sheet: The exams are closed book, but an equation sheet will be provided. The equation sheet is posted on the web. Students should familiarize themselves with the equation sheet by using it for homework. Attendance Policy: Attendance at lecture and recitation is expected. Attendance in recitation will be taken into account by the recitation leader when assessing each student's performance. Free Advice: Physics 21 is a fast paced course with a heavy workload. Assimilating the material presented each week is essential to understanding the following week's work. Come to class! Take notes! Keep up with the reading and homework assignments! Physics 19: Physics 19 is a one credit course for students who have taken a three credit course similar to (but less comprehensive than) Physics 21. Students taking Physics 19 should attend the first lecture on August 28 and then all the lectures and recitations beginning Tuesday, Nov. 6, 2007. They will take selected parts of the final exam. Disability: If you have a disability for which you are or may be requesting accommodations, please contact both your instructor and the Office of Academic Support Services, University Center C212 (6107584152) as early as possible in the semester. You must have documentation from the Academic Support Services office before accommodations can be granted.
