This item is an interactive lecture demonstration (ILD) on the topic of inertia. It features a massive ball suspended by a string with a string below. Using a rod, the demonstrator pulls or jerks down on the lower string. A steady pull always breaks the upper string; a jerk always breaks the lower string. 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.
