Product Summary
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.

High School / Physics
Students use hanging masses to apply torque to a rotating arm and measure its angular acceleration. After varying the torque, they experimentally determine the mathematical relationship between net torque and angular acceleration.
Advanced Placement / Physics
In this lab, students use rotary motion sensors to determine the mathematical relationship between torque, rotational inertia, and angular acceleration of a rotating object.
