Ring and Disc
Product Description

By: The Flinn Staff

It's a race! A ring and disc of equal mass and diameter speed down an inclined plane. Which one wins? Not an easy prediction to make but the victor will be clear. Results are explained using concepts of inertia, rotational inertia and potential and kinetic energy. Once students understand the results of the first race, they predict the outcome of a race between the ring and two discs-the second disc being larger than the first. Will the disc diameter make a difference? Includes one 3 1/2" diameter plastic ring, one 3 1/2" diameter wood disc, one 5" diameter wood disc, as well as instructions and detailed mathematical explanation of results. 3 1/2" diameter ring and disc are approximately the same mass.
