Introduction: Physics 141 is a calculus-based course focused primarily on classical mechanics. It is the first course in a sequence of three introductory foundation physics courses, where Physics 141 covers classical mechanics, Physics 142 covers electricity and magnetism and Physics 244 covers modern physics. The Text and Lectures: Reading the textbook is an essential part of the course. Students will benefit the most if they read the next section of text as listed in the course outline before coming to the lecture. Students are strongly encouraged to take accurate notes during the lecture and to ask relevant questions. Each student is individually responsible for the material covered in the book as well as each lecture. Homework: Homework is an essential part of the course, and the primary means by which you will discover if you understand the material. It is very important that you spend time working on understanding the problems. Working in small groups is often a useful environment to tackle difficult problems. Please note, you can also contact the tutors or instructors for help see the course web page for details. Homework assignments will be performed online at the Mastering Physics web page ( www.masteringphysics.com). Please be sure you select the correct text book link from this page i.e. Mastering Physics for Young/Freedman University Physics 12e. They will be due by 11pm on the day listed. The online system will always save your work so you can easily work on the problems continuously throughout the week. Do NOT leave it all for the last minute. The maximum value of a particular homework starts at full credit if completed on (or before) the due date and decreases after the due date such that homework completed one or more days late will be worth only 20%. To use this program, you should have received a Student Access Kit with your textbook purchase. Please follow the directions in the access kit for registering. The mastering physics course ID is 1
UICPHY141SPRING2009. If you did not purchase your textbook at UIC, then you will have to purchase separately (either online or at the book store) a student access kit for Mastering Physics. Physics is at its heart an experimental science, and the laboratory component of this course is an integral part of the course. Completion of the full laboratory part of the course is a requirement for passing Physics 141. That is, all experiments must be completed to pass this course. Make-up Labs must be scheduled with your lab TA on one of the allowed weeks for make-up labs. Unless your instructor says otherwise, the labs are to be completed during the scheduled lab time. There are two types of labs each is in a different room. Be sure to check which room you need to be in for each lab, it will vary from week to week. Standard Experiments are in room 2108 SEL -based Experiments are SEL Please note: Room 2108 is somewhat hidden at the back of one of the long hallways in SEL, around the corner. Grades: Final scores are based on the following 5 items, with the percentage weighting as given: Exam I 25% Exam II 25% Final Exam 30% Lab Work 12% Homework & Quizzes 8% A letter grade of A, B, C, D, or E is assigned according to what final score each student has earned. Common exams are given to all Physics 141 sections and a common grading system is applied. A grade of incomplete (I) is given only in special cases. All exams are closed book and it is the student s responsibility to be present at the scheduled time. Students must bring a working calculator and pens or pencils. Textbooks, cell phones, computers or any forms of wireless communication are strictly prohibited in an exam. Giving or receiving aid in an examination is cause for dismissal from the University. Any other violation of academic honesty can have the same effect. Study Hints: Always review your lecture notes before the next lecture. Leave enough time to ask someone for explanations if the notes are not understood. This is necessary because for the next lecture the instructor assumes you have understood all the previous lectures. When doing your homework, if you don t understand something, don t be afraid to discuss it with your classmates, instructors or tutors. It is more important that you make a complete write-up of the solution to problems and that you understand them, rather than to do all the work by yourself but not completely understand. Always complete the homework assignment by the due date because when the problems are discussed in class it is again assumed that you have attempted them and have thought about them. Course Web Site: The course web site is located at http://physicsweb.phy.uic.edu/141. This web site will list important course information including practice exams, solutions and contact information. It will also be the primary source of up-to-date information for what is happening in the Class. 2
