1. PHYISCS 110 How Things Work Physics 110 – Fall 2010 Prof. Martin Guthold Office: Olin 302, Lab: Olin 202 Phone: 758-4977 e-mail: gutholdm@wfu.edu OFFICE HOURS M, W, F, 1:00-2:00 pm, 302 Olin Feel free to drop by any time and I’ll try to accommodate you. TUTORIALS Some tutorials are held by Physics students. Hours/room will be announced. Physics 110 is a one-semester course in Introductory Physics. It does not require the use of calculus. The course is intended for liberal arts students. It is not for Pre-Med students or Science majors. SCHEDULE Lectures are Tuesday, Thursday, 1:30- 2:45 pm; room Olin 101 Each student must also enroll in one laboratory session. Laboratory sessions begin the week of Monday, Jan 25; room Olin 105. Failed lab = failed class!

2. TEXT AND MATRIALS The text is the 4 nd edition of How things work by Bloomfield (bookstore, or online). For the lab you must also obtain the lab manual in the bookstore (~ $15, bookstore). i-clicker (~ $ 30) EXAMS AND GRADING There will be one final exam and three 45 minutes midterm exams given at the dates listed below. Homework problems will be assigned for each chapter. The homework is due one week later in class. 1. Midterm exam 20% 2. Midterm exam 20% Final Exam 30 % Lab 15% Homework10% i-clicker5% (in-class multiple choice questions) attendance: 1 point correct answer: 1 point

3. Last day to add class:Wednesday, Jan. 27 Last day to drop class:Wednesday, Feb. 17 Exam 1:Tuesday, Feb. 16 Exam 2: Tuesday, April 13 Final:Tuesday, May 4, 2:00 – 5:00 pm No lectures on:Tu & Th, March 9 & 11 (Spring break) Exam dates & other important dates

4. HOMEWORK AND PROBLEM SOLVING Homework and problem solving is the most important part of learning in a course in physics. Approximately 15 questions or problems per chapter will be assigned as homework. Homework is due in class on due date. 80% grade if turned in by 5:00 pm on due date, 50% following two days. Some problems may also re-appear on the exams and the final. POSTINGS Lectures, homework, exam solutions, grades (listed by last four digits of student (ID), and other material relating to the course will be posted on the web site. http://www.wfu.edu/~gutholdm/Physics110/phy110.htm Try the Webpage at home. Download the lecture notes BEFORE class PRINT them out and BRING them to class. If you have problems, come and see me right away. Instructions on “How to print lecture notes (power point presentations)”: See hand-out.

5. ATTENDANCE In essence, attendance is taken via the i-clicker multiple choice questions (5% of the grade). Per i-clicker question: 1 point for attendance (any click) 1 point for correct answer Attendance at the two exams and the final is required - absence will result in a zero grade unless an official excuse is presented. Excuses should be reported to me in advance.

6. MONDAYTUESDAYWEDNESDAY THURSDAYFRIDAYSUNDAY PHY110 TUTOR SESSIONS (Hours to come soon) The tutor: Jillian Bjerke & Maggie Baldwin The tutor sessions in semesters past were very successful and received high marks from many students.

9. Demos: Understand them & and take notes. (May pop up in exam) Powerpoint presentations download them from http://www.wfu.edu/~gutholdm/Physics110/phy110.htm, print them out (e.g. three slides on a page) and bring to the lecture.) Blackboard Lecture format:

10. The book takes everyday objects and looks at the “physical concepts ” behind them. Shows that science is part of our everyday life. Goals: Begin to see the science in everyday life. Learn that science isn’t frightening. Learn to think logically in order to solve problems. Develop and expand physical intuition. Learn how things work. Things don’t just occur willy-nilly. Obtain perspective on history of science and technology. Book review READ THE TEXT BOOK!!!

11. Introduction: (principal theme + at home experiment + itinerary) Each chapter is divided into a few sections Each section: Check your understanding, figures answers at end of chapter Epilogue: connects studied objects and physical concepts Summary: summary + restatement of important laws and equations Exercises (explanations) Problems (numbers) Glossary at the end of the book Two appendices 1. Vectors; 2. Units Book review READ THE TEXT BOOK!!! Each chapter has the following features:
