AP Physics C – Syllabus 2008 – 2009 Goals There are two goals any introductory physics course must accomplish, regardless of the approach, emphasis, or pedagogical techniques: (1) to impart a qualitative understanding of the basic physics principles, and (2) to enable students to solve a variety of reasonable problems in topics presented in the text material. Course Description This physics course is a first year, college level, survey of the principal topics of physics. The class is designed to provide the student with a general knowledge of classical mechanics. Physics concepts will be stressed with a great emphasis placed on quantitative analysis. The objectives are set by The College Board who administers the AP Physics test in May. It is expected that all students successfully completing the AP Physics C course will take the AP test in May.

Teaching Strategies Lecture-Demonstration By working with the total group, I try to direct student thinking and problem solving strategies while deliberately moving through the key performance strategies. My role as a lecturer is more like that of a tour guide, showing the students important sites and having them think like physicists. By modeling thinking strategies, I try to show them how to approach new problems and situations. Large Group Discussion This gives students the opportunity to express their ideas to the entire class. I use this model for reviewing homework and test preparation. Small Group Discussion This gives the students the opportunity to work with 2 or 3 other students in the laboratory or during problem-solving sessions. In a small group, students are able to ask questions and offer suggestions without feeling self-conscious or intimidated. When a student explains a concept to another person, the student solidifies his/her own understanding of that concept. Working in small groups affords more students this opportunity. Individual Effort This model is used for all tests, all quizzes, and some problem-solving practice. Some of the best critical thinking is done alone. This allows me to monitor student progress and determine areas in which a student needs additional instruction. Grading Policy: I use a point system in which various assignments are worth a variety of points. The class average comes from points earned divided by total points possible. The point system allows me to appropriately weight individual assignments. A small assignment will be worth fewer points than a lengthier assignment. I am a prompt grader and return assignments quickly. Assessment Strategies: Students are assessed frequently in the following manner. Unit tests are administered at the conclusion of large units (those denoted by a capital letter in the course outline). Topic tests are also given at the conclusion of a topic. There may be several topic tests before a unit test is given. Quizzes are administered at least weekly, as well as graded homework problem sets. About the AP Physics C Course: This course is calculus-based and takes place 5 days per week for 55 minutes each day for the entire school year. The topics presented during the course closely follow those delineated by The College Board. This course mirrors an introductory level university physics course. The goal of the course is for students to master the concepts and principles of physics from two approaches: mastery of concepts and proficient use of formulae to solve problems. Hands-on, inquiry base investigations will also be included to discover principles and strengthen understanding. Outline of Topics I. Chapter/Sections Newtonian Mechanics A. Kinematics (2 weeks) 1.

AP Physics C Laboratory Activities Average Versus Instantaneous Speed The purpose of this lab is to investigate the relationship between instantaneous speed and average speed, and see how a series of average speeds can be used to deduce an instantaneous speed Projectile Motion Lab The objective of this laboratory is to predict the range of a projectile set in motion at an arbitrary angle. Static Equilibrium Lab The purpose of the laboratory experiment is to use vector analysis to mathematically predict and with a force table to experimentally verify static equilibrium conditions. Coefficient of Kinetic Friction Lab To compare the theoretical acceleration of the air track cart with the calculated acceleration from experimental results. To determine the coefficient of kinetic friction between the air track cart and the masking tape on the air track. Inclined Plane Lab To determine the coefficient of kinetic friction, µk, between an object and a surface. To determine the tension in the string between two objects. Atwood’s Machine To compare a theoretical value for the acceleration of the system with an experimentally determined value for acceleration. Terminal Velocity Lab To investigate the effects of air resistance on a falling objects. Center of Mass Lab To demonstrate the concept of center of mass and its relationship to balancing. Explosions and Collisions Lab To gain experience applying the principle of conservation of linear momentum and the concept of center of mass to actual physical situations. Centripetal Force Lab Students determine the effects of varying mass, radius, and the centripetal force acting on an object. Conical Pendulum Lab To compare the theoretical and experimental value for the period of rotation of a toy plane traveling in a uniform circular path. To determine the tension in the string attached to the toy plane as it travels in its uniform circular path. To determine the linear speed and centripetal acceleration of the toy plane. Torque Wrench Lab (Virtual) http://www.usna.edu/MathDept/website/courses/calc_labs/wrench/TorqueWrench.html This applet demonstrates torque by allowing the user to adjust wrench length and position and force vector and see the resulting magnitude of the torque.
