This high-resolution video lets students explore conservation of momentum in a cannon-pendulum system. A small metal ball is fired from a pneumatic cannon into a sticky surface of a weighted pendulum. Students can measure the position and time for the ball after it is launched (but before it hits the pendulum) and the swing angle of the pendulum after the ball strikes it. Mass of the marble and the pendulum apparatus are given. Learners will determine the momentum of the steel ball before it hits the pendulum to predict the maximum swing angle.
Direct Measurement Videos allow students to easily analyze physical situations encountered in introductory mechanics courses. Features include digital rulers, frame-counters, and other screen overlays for making precise measurements. Video can be streamed or viewed in stepped motion to analyze frame-by-frame action. This material is part of Pedagogy in Action, a library of resources for educators provided by SERC, the Science Education Resource Center. Please note that this resource requires Quicktime. Editor's Note: See Related Materials for an interactive homework problem that would be an excellent companion resource for this DVM video. It takes students step-by-step through a conceptual and strategic analysis to solve an almost identical problem involving a bullet fired into a pendulum.
