Vernier Rotary Motion Sensor User Manual

Vernier Rotary Motion Sensor
(Order Code RMV-BTD)
The Vernier Rotary Motion Sensor is a bidirectional angle sensor designed to
measure rotational or linear position, velocity and acceleration. It is used for a
variety of investigations, including measurement of rotational inertia and
verification of the conservation of angular momentum.

Using the Product
Example Experiments
The following examples show various ways to use the Rotary Motion Sensor.
Some of these examples use accessory products described below.
for a list of software compatible with the
Atwood's Machine
Attach the 3-step pulley to the rotating shaft. Use the thumb screw to attach the
Rotary Motion Sensor to a ring stand. Attach each end of the string to a mass
and run the string over the pulley. Use the Rotary Motion Sensor to determine
the acceleration of the system.
Moment of Inertia of a Disk
(requires Rotational Motion Accessory Kit, see Accessories section)
Attach an Ultra Pulley to the Rotary Motion Sensor. Attach the 3-step pulley to
the rotating shaft. Attach the disk to the 3-step pulley. Attach a string to the
underside of the hub. Attach the Ultra Pulley to the Rotary Motion Sensor using
the Ultra Pulley Swivel Mount. Run the string over the Ultra Pulley and attach
a weight to the end of the string. Use the weight to apply a torque to the system
while the Rotary Motion Sensor measures the angular acceleration.
