The Go Direct Rotary Motion Sensor and Rotational Motion Accessory Kit can be used to study rotational inertia, conservation of momentum, and additional rotational motion concepts.

Monitor angular motion easily and precisely with the Go Direct Rotary Motion Sensor, which connects via Bluetooth^® wireless technology or via USB to your device. The wireless connection eliminates the cables that can get caught and tangled during rotational investigations.

• Determine position, velocity, and acceleration of objects in angular motion.
• Measure angle increments as small as 0.25°.
• Investigate rotational dynamics, conservation of angular momentum, pendulum motion, polarization of light, and more.
