Add the CI-6691 Mini-Rotational Accessory to the Rotary Motion Sensor to study the oscillations of a pendulum, the rotational inertia of an aluminum disk, a steel ring and a metal rod, as well as the conservation of momentum during a rotational collision. The clamp-on Super Pulley allows students to apply a torque by hanging a mass over the pulley.

Conservation of Angular Momentum:

·       To demonstrate conservation of angular momentum, a non-rotating ring is dropped onto a rotating disk. 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.

Includes:

·       Rotating Disk (9.5 cm diameter, 120 g)

·       Large Ring Mass (465 g)

·       38 cm Pendulum Rod (27 g)

·       75 gram Masses (quantity 2)

·        Clamp-On Super Pulley
