PHYSICS 218: Mechanics (Spring 2008) Corequisites MATH 151. You are expected to have a working knowledge of plane geometry, trigonometry, and algebra. As the semester progresses you will also be expected to have a working knowledge of derivatives and integrals, and be proficient in the use of vectors (addition, subtraction, dot and cross products). Instructor Dr. Hans A. Schuessler Office: Engineering-Physics building, Room 407 Phone: 845-5455 E-mail: [email protected] Office hours: Wednesday 10-11 AM and by appointment Homepage http://physics218.physics.tamu.edu for general information http://sibor.physics.tamu.edu for a better source of information and handouts. This course is available on-line on a trial basis. (Instruction of how to log on will be given) Textbooks “University Physics” 11th ed. by Yong&Freedman (Volume 1) “Laboratory Experiments for Physics 218” 9th ed., by Ramirez, Seidel, and Hiebert (Hayden-McNeil Publishing) Rec. & Lab Recitation meets in 118 Heldenfels Hall for the first hour, and is followed by a Laboratory session the remaining two hours. No Lab sessions and Reports will be dropped. Students retaking the course should contact me immediately in order to get credit for Lab if passed in a previous semester with a grade of 80 or better. Students retaking the course do not have to repeat the Lab but they are required to attend Recitation and take weekly quizzes. Note: There will be a recitation or lab meeting during the first week of the semester for the visual physics sections(Phys 515-518), but no recitation and lab for the other sections (Phys 505-508). Homework and Quizzes Homework assignments and math quizzes will be turned in using WebCT(http://.webct.tamu.edu). Instructions on using WebCT for Physics218 may be found at http://faculty.physics.tamu.edu/toback/WebCT/. Homework assignments are for you to practice problem-solving techniques. Homework will be graded weekly by WebCT. About 10 quizzes will be given in Recitation. Each quiz will test your ability to work one of the assigned homework problems. There may also be a few unannounced pop quizzes during lecture. Exams There will be three midterm exams and one final exam: (a) Each midterm exam will be given during the regular classroom time and will last 50 minutes, while the final exam is comprehensive and lasts for 2hours. Each exam will generally consist of problems similar in content and difficulty to the homework. The entire solution will be graded and partial credit given if merited. Your work must show the steps toward the solution; the answer alone is not sufficient. The grader will judge your use of physics in arriving at the solution. Exams may also include Examples worked in the lecture but not appearing in the text nor assigned as problems. (b) Formula sheets will be provided for each exam and the final. Copies of each are on my web site http://sibor.physics.tamu.edu (c) You will need to bring a calculator to the exams. (d) If you miss an exam due to an authorized excused absence as outlined in the University Regulations, then you must contact me no later than the next class meeting following the missed exam to arrange for a makeup exam. There will be a single course-wide makeup exam for those missing an exam. This makeup exam will be written by a committee of Physics 218 lecturers and administered outside normal class time within 7-10 class days following the missed exam. Note: Very few conditions qualify as an authorized excused absence, so avoid missing an exam at all costs. Students typically do worse on makeups than on regular exams. (e) You must bring your student ID with you to all exams for identification purposes. Exam Grade Exam grades may be curved depending on special conditions of a particular exam. In no case will a curve result In a lower letter grade than the standard 90-100% A, 80-89% B, 70-79% C, 60-69% D, and <60% F. The total course grade consists of 700 points distributed as follows Course Grade Points 3 Midterm Exams 300(100, 100, 100) Final Exam 200 Laboratory Lecture and Recitation Quizzes 100 50 WebCT Homework and Math Quizzes 50 Total 700 NOTE: You must pass both the lecture (3 midterm exams, final exam, recitation & lecture quizzes), Homework (100% on all homework, homework quizzes and 100% Math Quizzes) and laboratory (≥70%) parts of the course separately in order to pass the course.ADA Policy The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities.
