PHYSICS 218: Mechanics (Fall 2004)Corequisites MATH 151. You are expected to have a working knowledge of plane geometry, trigonometry, andalgebra. As the semester progresses you will also be expected to have a working knowledge ofderivatives and integrals, and be proficient in the use of vectors (addition, subtraction, dot andcross products).Instructor Dr. George R. WelchOffice: Engineering Physics, Teaching/Lab Wing Room 209Phone: 847-8593.Email: [email protected] hours: Monday and Tuesday, 8:30 – 10:00 a.m., and by appointment.Web Sites http://leona.physics.tamu.edu/Phys218.04f/http://physics218.physics.tamu.edu/Textbooks University Physics, 11thed. by Young and FreedmanPhysics 218 Lab Manual, 8thed., 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 sessionthe remaining two hours. No Lab sessions and Reports will be dropped. Students retaking thecourse should contact me immediately in order to get credit for Lab if passed in aprevious semester with a grade of 80 or better. Students retaking the course do not have torep eat the Lab but they are required to attend Recitation. Note: There will be no recitationor lab meetings during the first week of the semester.Quizzes There will be daily quizzes during the lecture session. These will not be trivial, and will either testthe material you should have read before class, or the material just presented. You may be requiredto bring scan-tron sheets. In that case, you will be told so in advance.Homework Homework assignments (see next page) and math quizzes will be turned in using webCT. TheURL is http://webct.tamu.edu . Instructions on using webCT for Physics 218 may be foundat http://faculty.physics.tamu.edu/toback/WebCT/ . Homework assignments are for you topractice problem-solving techniques. The homework listed on the following page is a minimumset, and will be the source for the WebCT problems. I will also assign supplementary problems,or hand out others, as the semester progresses. Some of those may be handed in for grading, andothers not.Exams There will be three midterm exams and one final exam: (a) Each midterm exam will begiven during the regular classroom time and will last 75 minutes, while the final exam is compre-hensive and lasts for 2 hours. Each exam will generally consist of problems similar in content anddifficulty to the harder homework problems, and the examples from class and the book. The entiresolution will be graded and partial credit given if merited. Your work must show the steps towardthe solution; the answer alone is not sufficient. The grader will judge your use of physics in arrivingat the solution. (b) Formula sheets will be provided by the department for each exam and the final.I don’t write them. I don’t know what’s on them. I hate formula sheets. (c) If you miss an examdue to an authorized excused absence as outlined in the University Regulations, then you mustcontact me no later than the next class meeting following the missed exam to arrange for a makeupexam. Note: Very few conditions qualify as an authorized excused absence, so avoid missing anexam at all costs. (d) You must bring your student ID with you to all exams for identificationpurp oses.Exam Grade Exam grades may be curved depending on special conditions of a particular exam. In no case willa 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.CourseGradeThe total course grade consists of 750 points distributed as followsPoints3 Midterm Exams 300 (100 points each)Final Exam 200Lab oratory 100Lecture Quizzes 100WebCT Homework and Math Quizzes 50Total 750NOTE: If your final exam grade is higher than your 3-exam average, then the final will count300/750 points toward your final grade and your midterm exam average will count just 200/750.ADA Policy The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensivecivil rights protection for persons with disabilities. Among other things, this legislation requires that all studentswith disabilities be guaranteed a learning environment that provides for reasonable accommodation of theirdisabilities. If you believe you have a disability requiring an accommodation, please contact the Department ofStudent Life, Services for Students with Disabilities, in Room 126 of the Koldus Building or call 845-1637.Honor Code The Aggie Honor Co de states, “An Aggie does not lie, cheat, or steal or tolerate those who do.”Further information regarding the Honor Council Rules and Procedures may be found on the web athttp://www.tamu.edu/aggiehonor .Tentative Class ScheduleNOTE: This is an example only!
