The PASPORT Rotary Motion Sensor measures position, velocity, and angular and linear acceleration.
See the Buying Guide for this item's required, recommended, and additional accessories.
The PASPORT Rotary Motion Sensor is used to measure position and motion within physics labs. It measures position, velocity, and acceleration, both angular and linear, with incredible resolution and accuracy. The maximum spin rate of 30 rev/sec and bi-directional orientation enables the PASPORT Rotatory Motion Sensor to facilitate the performance of most motion experiments
How it Works: The 6.35 mm diameter, dual ball-bearing shaft extends from both sides of the unit, providing an excellent platform for rotational experiments. The rod clamp, which can be attached to three sides of the sensor, allows the unit to be mounted in almost any orientation. A three-step pulley and a mount for the PASCO Super Pulley make torque experiments easier than ever before.
- Three-step pulley (10, 29, and 48 mm in diameter)
- Rod clamp for dynamic mounting orientations
- Measures magnitude and motion direction.
- Ball bearings minimize friction and provide mechanical support to rotating objects
- Verify the conservation of angular momentum
- Calculate the rotational inertia of a disk ring and point mass
- Measure the displacement velocity and acceleration of a cart on a track
- Conduct quantitative analysis of simple harmonic motion
- Measure the acceleration of a cart caused by a mass hung over a pulley
- Accurately measure the angular acceleration of systems with constant torque

This lab investigates the potential energies for a modified Atwood's Machine, where a disk has been added to the Rotary Motion Sensor pulley.
A rod oscillates as a physical pendulum. The period is measured directly by the Rotary Motion Sensor, and the value is compared to the theoretical period calculated from the dimensions of the pendulum.
This experiment explores the oscillatory motion of a physical pendulum for both small and large amplitudes. Waveforms are examined for angular displacement, velocity and acceleration, and the dependence of the period of a pendulum...
The relative light intensity versus distance from a point light source is plotted. As the Light Sensor is moved by hand, the string attached to the Light Sensor that passes over the Rotary Motion Sensor pulley to a hanging mass...
The purpose of this experiment is to use measurements of the motion of a simple pendulum to calculate and compare the different types of energy present in the system.
A rod rotates in a horizontal plane, and is made to slow steadily to a stop. This setup is used to explore the different types of acceleration involved in this motion: centripetal, tangential, and angular acceleration.
