Playground Physics: Determining the Moment of Inertia of a Merry-Go-Round
Van Hook, Stephen; Lark, Adam; Hodges, Jeff; Celebrezze, Eric; Channels, Lindsey
Physics Teacher, v45 n2 p85-87 Feb 2007
A playground can provide a valuable physics education laboratory. For example, Taylor et al. describe bringing teachers in a workshop to a playground to examine the physics of a seesaw and slide, and briefly suggest experiments involving a merry-go-round. In this paper, we describe an experiment performed by students from a Society of Physics Students organization and their faculty advisor on a merry-go-round at a local park. The goal of the activity was for everyone to gain a greater understanding of the concepts of angular velocity, centripetal acceleration, moment of inertia, and conservation of angular momentum through their own personal experience--and to have fun, too.
