Our Rotary Motion Sensor may be the most useful sensor in physics! Use it to study optics, dynamics, centripetal force, the motion of a pendulum and many other topics. Measures position, velocity and acceleration (angular and linear) with incredible (0.09 º) resolution and accuracy. A higher maximum spin rate (30 rev/sec) allows students to perform a full range of motion experiments.
- Measures magnitude and direction of motion.
- Ball bearings minimize friction and provide mechanical support to rotating objects.
- 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

1 Minimum # of data points with all measurements enabled, actual results depend on enabled measurements.
2 Continuous use in a connected state until battery failure, actual results will depend on sample rate, active measurements, and battery condition.
3 Logging until battery failure, actual results will depend on sample rate, active measurements, and battery condition.
* Normal classroom use is the sensor in active use for 20min/lab for 120 lab periods/yr.
