Knight, ISBN This textbook bundle is available at the Bookstore. Alternatively, if you wish, you can purchase a MasteringPhysics License with ebook, directly from the publisher. If you choose this option, you must make sure to purchase the ebook option as well, so that you will have access to LearningCatalytics. ISBN is the code for the correct version to purchase online. Smartphone, Tablet or Laptop: You will need a device that can support a web browser in class in order to participate in the LearningCatalytics exercises in lecture -1-

2 Class Format: Lecture: The 50 minute MWF Lectures, will be a supplement to your reading and other prefecture assignments. These periods will be used to help strengthen your conceptual understanding of the material, as well as to help you develop problem solving skills, through the use of conventional lecture format as well as interactive LearningCatalytics exercises. Your participation in the lecture exercises will affect your grade directly, as explained in the "Evaluation" section of the syllabus. Lab: NOTE: The lectures are not a substitute for your textbook reading assignments. The purpose of the lecture is to amplify the key points and to help clarify some of the more difficult aspects of the reading assignment. The lecture is not the place to encounter the material for the first time. In your laboratory section, which meets weekly on Tuesday or Thursday, you will perform a number of experiments to investigate the topics that we present in lecture. Your lab section s BlackBoard page has more detailed information about the structure of the lab component of Physics 31. Optional Problem Solving Session, Physics 30A: Physics 30A is an optional 1- credit course, meeting weekly on Thursday evenings, 6:00 7:15 p.m. devoted to discussing how to solve the Physics 31 homework assignments. If you feel that you might need some extra help in this regard, consider adding this course. Note on MasteringPhysics: The first time you log into MasteringPhysics and enter your registration information, you should join our course: MPSANDERS82081 and follow the directions for joining this section (you will need to provide your netid - the thing you use to access my and , like "mmsander", NOT the numerical string that begins with 9...) Physics 31 Course Objectives The specific objectives of this course are that, upon successful completion of Physics 31, students will be able to: 1. Manipulate vector physical quantities and analyze graphs. 2. Perform a quantitative analysis of linear and rotational motion. 3. Draw a free-body diagram of particles and rigid bodies and employ Newton s laws to calculate acceleration or work done by various bodies or systems of particles. 4. Employ energy and momentum concepts and conservations laws to find physical quantities that describe kinematics and dynamics of various bodies or systems of particles. 5. Calculate moment of inertia and center of mass for rigid bodies. 6. Apply the fundamental kinematics, dynamics and energy concepts (see objectives 1 4) to study harmonic oscillations and mechanical waves. 7. Conduct and troubleshoot experiments that investigate the physical phenomena and principles explored in Effectively communicate the results of these experiments, subsequent data analysis and conclusions in a written report. -2-

3 Physics 31 B Spring 2018 Lecture Schedule The following is a tentative list of dates and allocations of time to be devoted to each of the relevant chapters and sections of the textbook. It is very important that you read the material in the textbook before coming to the lectures that are scheduled to cover this material. In lectures, I will assume that you will already have some familiarity with the new terms and concepts that are presented in each of the chapters. Many days, I will assign prelecture question on MasteringPhysics that will be due the night before lecture meeting. Also, in lecture there will often be LearningCatalytics questions that you will answer in lecture for which you may need to rely on your knowledge of the reading material. It will also be useful for you to have attempted, or at least looked at, the homework problems for the chapter we are covering, before you come to lecture. Check the Physics 31 B Blackboard site to make sure we re still on schedule.

5 Physics 31 B - Assigned Questions and Problems Complete the assignments by the dates shown. Many of the assigned problems will appear on the MasteringPhysics assignment due at midnight of the due date for the homework assignment. Each chapter assignment in MasteringPhysics is coupled with an Adaptive followup assignment, worth 3 points. If you score 90% or higher on the parent assignment, you automatically get the Adaptive points without doing anything else. If you score below 90% on the parent assignment, then you will need to answer about three sets of followup questions correctly to get the points for the adaptive followup assignment. The following assigned conceptual questions (CQ) and problems (P) should to be completed by the dates shown. Solutions to the assigned problem sets will be posted on the Physics 31 BlackBoard site after the due dates have passed. Due Date Chap. Assigned Questions and Problems Jan 28 1 P: 23, 24, 25 2 CQ: 4, 5, 6, 7, 12, 13 P: 2, 6, 8, 11, 12, 16, 20, 21, 23, 27, 37, 40, 84 Feb 4 3 CQ: 2, 3, 4, 8 P: 1, 11, 13, 20, 23, 32, 33, 40, 43 4 CQ: 1, 2, 4, 7, 8 P: 4, 5, 14, 18, 20, 47, 49, 50, 55, 58, 76, 82 Feb 19 5 CQ: 2 5, 7, 8, 13, 14 P: 17, 33, 34, 42, 43, 44, 46, 48, 52 Feb 25 6 CQ: 1, 5, 6, 12, 13, 16 P: 1, 2, 11, 39, 42, 48, 56, 58, 67 7 CQ: 7, 11, 12, 13, 14, 15 P: 4, 5, 7,17, 23,24, 25, 33, 37, 38, 39, 45, 57 March 4 8 CQ: 2, 3, 5 P: 10, 21, 47, 48, 51, 55, 69 Mar 18 9 CQ: 1, 2, 7, 9, 12, 13 P: 8, 10, 11, 12,14, 15, 18, 29, 34, 42, 49, 52, 62, 70 Mar CQ: 4 8, 12 P: 2, 5, 9, 11, 16, 18, 26, 27, 30, 32, 38, 39, 44, 45, 54, 69 April 1 11 CQ: 4, 6, 10, 12 P: 8, 13, 14, 15, 19, 20, 25, 27, 31, 32, 46, 48, 49, 53, 68, 71, 83 April 8 12 CQ: 2, 4, 10, 11, 13 P: 13, 20, 32, 43, 44, 60, 62, 75, 86 April CQ: 2, 6, 8 P: 5, 26, 35 38, 47, 57, 71 April CQ: 1, 2, 3, 4, 9 P: 5, 6, 16, 34, 43, 56, 58, 64, 72, 78 April CQ: 1, 3, 4, 7, 8 P: 4 7, 35, 46, 48, 54, 57, 60, 74, 76, 80 Practice 17 CQ: 3, 4, 7, 10 P: 1 3, 5, 7, 34, 40, 44, 50, 54, 58, 64, 68-5-

6 Physics 31 - Evaluation Your final grade in Physics 31 will be determined by your performance on the hour exams and the final exam, your lab work, your MasteringPhysics homework and your lecture participation via LearningCatalytics according to the following table: LearningCatalytics&Prelecture(lecture) 10% MasteringPhysics(homework) 20% Exam 1 (2/8) 10% Exam 2 (2/27) 10% Exam 3 (3/29) 10% Lab 20% Final Exam (5/7) 20% Exams: Students will be expected to take examinations at the scheduled times. A grade of zero will also be recorded for a missed hour examination or final examination unless circumstances beyond the student s control prevent participation at the scheduled time. If you anticipate a problem, see me as far in advance as possible. Documented evidence of such circumstances will be required in order to schedule a makeup for an hour examination or for the final examination. Physics 31 exams will be "closed-book." No books or notes are to be brought into the examination; a student should bring only pen or pencil (and eraser). Exception: A formula sheet will be provided for each of the hour exams and the final exam. Electronic calculators will not be permitted for use during exams. Most of the questions on examinations and quizzes will be problems adapted from the homework assignments. However, there will also be some questions aimed at probing conceptual understanding in other ways; these will be of the True/False, multiple choice, or short answer format. Students who are concerned about their performance in the course are encouraged to discuss the matter with their instructor. Please note that Monday, April 3, is the last day to withdraw from courses. Students who withdraw from Physics 31 must also withdraw from the associated problem solving course, Physics 30. Students will be expected to comply with the University s Academic Honesty policy. No talking or other communication is permitted during quizzes or examinations. -6-
