Disk and Ring Race Demonstation Set - Observe Rotational Inertia Properties - Includes 2 Disks & 1 Ring

• Race combinations of the 3 objects down an incline to demonstrate how rotational inertia is dependent on their mass and how that mass is distributed from the axis of rotation. The object with the greater rotational inertia will always lose the race
• Both disks are made of sanded and varnished hardwood to minimize friction. The smaller disk and ring have identical masses and radii in order to have the same inertia but different rotational inertia. The 2nd disk has exacly twice the mass and a much larger radius
• Ideal physics classroom aid to supplement physics studies of force and motion
• Real application of abstract concepts
• Set includes wooden disk, 5" diameter, 6oz (1); wooden disk, 3.5" diameter, 3oz (1); metal ring, 3.5" diameter, 3oz (1)

The Disk and Demonstration Race Set recreates a classic physics experiment and allows your students to observe real applications of abstract concepts. Rotational inertia is a measure of the resistance to a change in the state of rotational motion and is dependent on an objects mass and how that mass is distributed from the axis of rotation. This can be observed by racing combinations of the disks and ring down an incline. The object with the greater rotational inertia will always lose the race.

Set includes one metal ring: 3.5" diameter, 3oz; and two wooden disks: 5" diameter, 6oz & 3.5" diameter, 3oz
