Rotary Motion Laboratory

Use this compact multi-purpose system to demonstrate conservation of angular momentum in collisions. Learn more

Complete Rotational System

Demonstrate conservation of angular momentum in collisions--plus much more. This complete system is valuable for a wide range of rotation experiments. Learn more

Gyroscope

Show how the direction of the angular momentum is significant when conserving angular momentum with this bicycle wheel gyroscope and rotating platform. Learn more

The Rotary Motion Laboratory is based on the Rotary Motion Sensor.

For Conservation of Momentum, drop ring on disk or drop disk on disk

• Compact size
• Includes experiments

Here's What You Need:

• Rotary Motion Laboratory, PASPORT (ME-6551A)
• Rotary Motion Laboratory, ScienceWorkshop (ME-6540A)

The Complete Rotational System has three different ways to conserve angular momentum.

Experiment 1. Drop ring on disk or drop disk on disk. Enlarge Image

Experiment 2. Pull a point mass inward. Enlarge Image

Experiment 3. Shoot a ball into the catcher on the rotating platform. Enlarge Image

Here's What You Need:

• Complete Rotational System (ME-8950A)
• Photogate Head (ME-9498A)
• 750 USB Interface (CI-7650) - For use with ScienceWorkshop

or

• Digital Adapter (PS-2159) and USB Link (PS-2100A) - For use with PASPORT

Additional Equipment Needed for Experiment 3:

• Projectile Catcher Accessory (ME-6815)
• Projectile Launcher (Short Range) (ME-6800)

or

• Projectile Launcher (Long Range) (ME-6801)

Show how angular momentum is conserved including direction:

• Start with the stool at rest and the bicycle wheel rotating so the angular momentum points up.
• Turn the bicycle wheel upside down: The stool will rotate so the total angular momentum is still up.

Here's What You Need:

• Bicycle Wheel Gyroscope (ME-6833)
• Discover Rotation Platform (ME-6834)

Measure the speed: Add a Photogate Head (ME-9498A) to the base of the Discover Rotation Platform and measure the angular speed with a Smart Timer (ME-8930).
