The Vernier Rotary Motion Sensor is a bidirectional angle sensor designed to measure rotational or linear position, velocity and acceleration.
The Rotary Motion Sensor lets you monitor angular motion precisely and easily. It is direction sensitive. You can use it to collect angular displacement, angular velocity, and angular acceleration data. Typical experiments include measuring moments of inertia, torque, pendula, and Atwood’s machine experiments. Even though we call it a Rotary Motion Sensor, it can also be used to measure linear position to a fraction of a millimeter.

This accessory kit is used with the Rotary Motion Sensor to study the motion of a physical pendulum; the rotational inertia of disks, rings, and point masses; and the conservation angular momentum. The kit includes:
- 2 3-1/2 inch diameter, 1/4 inch thick solid aluminum disks
- 1 steel disk with 1-1/8 inch central hole
- 1 plastic hub to hold the steel disk on the 3-step pulley
- 1 15 inch hollow aluminum rod
- 1 Ultra Pulley
- 1 Ultra Pulley Swivel Mount, which allows the pulley to be mounted on the Rotary Motion Sensor
- 2 Masses with locking screws

This kit includes a small electric motor with pulley, rubber band belt, motor clip, and mounting screw. The motor can be attached to the Rotary Motion Sensor, and be used as an analog tachometer, or generator. You can also perform experiments that investigate motor efficiency in different conditions.
