Description
The Wireless Rotary Motion Sensor measures angle, angular velocity, and angular acceleration, as well as their linear equivalents. The included three-step pulley allows different torques to be applied, rotating a rigid system at different rates of acceleration. The included rod-mounting holes let you orient the sensor for different experiments. The Wireless Rotary Motion Sensor connects directly to your devices via Bluetooth or USB.
- Measures magnitude and direction of motion.
- Ball bearings minimize friction and provide mechanical support to rotating objects.
Typical Applications
- Verify conservation of angular momentum
- Calculate rotational inertia of disk ring and point mass
- Measure displacement velocity and acceleration of a cart on a track
- Conduct quantitative analysis of simple harmonic motion
- Measure acceleration of a cart caused by a mass hung over a pulley
