Ring And Disk Set - ME-3419
Use this set to demonstrate Conservation of Angular Momentum.
Product Summary
Demonstrate Conservation of Angular Momentum with this set of 2 disks, a ring of equal mass, and 3 alignment guides.
To demonstrate conservation of angular momentum, a non-rotating ring is dropped onto a disk that is rotating on a Wireless Rotary Motion Sensor (PS-3220) or a PASPORT Rotary Motion Sensor (PS-2120). The angular velocity of the disk is recorded in real time and students can easily determine the angular velocities of the disk just before and after the ring is dropped. Combining these velocities with the rotational inertia of the disk and ring, students can confirm that angular momentum is conserved.
An alignment guide is placed on top of the rotating disk and is threaded onto the shaft of the Rotary Motion Sensor. This guide helps to align the ring precisely when it is dropped onto the spinning disk.
