Physics 7A Kinematics Lab 1 (v. 8.0) p. 1 NAME _____________________________ PARTNER ___________________________ DATE _________________ GSI ___________________ LAB DAY/TIME __________ KINEMATICS LAB 1: POSITION AND VELOCITY Introduction In this lab, you will produce position and velocity graphs, by walking in front of a detector. The main idea is for you to become comfortable at translating back and forth between graphs and real- life motion. At the end we'll do something a little different just for fun. In most courses, lab and discussion sections are separate activities. But we deliberately combine hands-on activities with worksheet-style conceptual questions. That way, you can continually integrate your hands-on experiences with more abstract knowledge, to achieve a deeper understanding. If you took honors high school physics, much of this lab will be review. Since some students never took physics before, however, we want to make sure that everyone gets up to speed (excuse the pun!) on this crucial material. We’ve also included some starred questions that should challenge everyone, and some harder challenge questions marked with a double star. You might want to save some of these harder questions—especially the double starred ones—until after you’ve completed the rest of the lab. A Note About “Predictions” Throughout your Physics-7 labs, you will be asked to make “predictions” about the outcome of most experiments before you do them. The correctness of these predictions will never be graded. We do not expect you to know what a particular outcome will be before you do an experiment, but we do expect you to think about, predict, and record your prediction for what the outcome will be. This technique of “predict before doing” is designed to keep everyone actively thinking about the concepts, and to help you focus on those areas you may not yet fully understand. (We would much rather have you make the errors you need to make here , in lab and discussion section, rather than on an exam.) Whenever you and your lab partner disagree about a prediction, see if you can understand why—you’ll both benefit. We force you to make these predictions because we want you learn as much as possible from each lab. We know that that’s much more likely to happen if you’re actively engaged throughout each session, making sense of your own beliefs and preconceptions at each stage. If a particular outcome doesn’t match your prediction, by explaining why you’ll learn something—and that’s the whole point! Otherwise it’s just too easy to work your way through the labs without ever really thinking about what’s going on. Indeed, in the past some students have gotten exam questions wrong because they misremembered what they saw in lab, answering with what they thought should have happened rather than with what really happened. Reconciling what you expect with what really happens—while in lab!—will help you avoid this problem.
