Conservation of Angular Momentum

A non-rotating ring is dropped onto a rotating disk. The angular speed is measured immediately before the drop and after the ring stops sliding on the disk. The measurements are repeated with a non-rotating disk being dropped onto a rotating disk. For each situation, the initial angular momentum is compared to the final angular momentum. Initial and final kinetic energy are also calculated and compared.

Featured Equipment

550 Universal Physics System

Universal 550 Physics Experiment Bundle

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.

550 Universal Interface

550 Universal Interface

The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.

PASPORT Rotary Motion Sensor

The PASPORT Rotary Motion Sensor measures position, velocity, and angular and linear acceleration.

Rotational Inertia Accessory

Rotational Inertia Accessory

Add the Rotational Inertia Accessory to a PASCO Rotary Motion Sensor (PS-3220 pr PS-2120) to study rotational inertia of a disk, ring, and point masses.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
