This item is an interactive lecture demonstration (ILD) that helps students understand the Law of Inertia as it relates to circular motion. It features a pie plate with a wedge cut out. A metal ball is then spun around the rim of the plate. The inward force of the rim keeps the ball in circular motion until the rim ends, when the ball flies off in a straight line, obeying Newton’s First Law. The action is animated to clearly illustrate how the demonstration should appear in the physics classroom. This item is part of a much larger collection of multimedia teaching resources which includes a database of ILD's, simulations, and video clips, compiled by the UCLA Department of Physics and Astronomy. SEE RELATED ITEMS BELOW for a link to the full collection.
