The PASPORT Motion Sensor accurately measures the position, velocity, and acceleration of a target. It can be used to track the motion of balls, carts, people, and more.
See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
The PASPORT Motion Sensor is used to measure the position, velocity, and acceleration of a target. The Motion Sensor can be set on a desktop, mounted to a rod stand, or attached to a PASCO Dynamics Track. The ultrasonic, pulse-ranging technology has a switch-selectable Standard Beam or Narrow Beam that rejects false signals for cleaner data collection.
Features
- Measures position, velocity, and acceleration
- False Target Rejection Technology collects clean data
- Switch-selectable short range and long range settings
- Snaps onto PASCO dynamics tracks
- Mounts to rods for easy positioning
- 360° pivoting head
Applications
- Discover the relationship between position, velocity, and acceleration
- Measure the motion of large objects, including students
- Monitor the sinusoidal motion of a mass on a spring
- Study conservation of energy and momentum during collisions
How It Works
An electrostatic transducer in the face of the Motion Sensor transmits a burst of 16 ultrasonic pulses with a frequency of about 49 kHz. The ultrasonic pulses reflect off the target and return to the face of the sensor. The target indicator flashes when the transducer detects an echo. The sensor measures the time between the trigger and echo rising edges, then, it uses this time and the speed of sound to calculate the object's distance. To determine velocity, it uses consecutive position measurements to calculate the rate of change. It similarly determines acceleration by using consecutive velocity measurements.

Experiment Library
Perform the following experiments and more with the PASPORT Motion Sensor.
Visit PASCO's Experiment Library to view more activities.
Near and Far
In this lab, students use a motion sensor to describe the position of an object as being near or far from another object. This lab will help students recognize that an object in motion changes its position.
Work-Energy Theorem
A force sensor is used to measure the changing force applied by a stretched elastic cord, while a motion sensor records the resulting velocity of the cart. The work done by the elastic cord is compared to the increase in kinetic...
Position and Velocity
In this lab, students will investigate the relationship between position and velocity using a Motion Sensor to measure the position of a motorized cart.
Oscillation Equations of Motion
The motion of an oscillating mass is measured using a Motion Sensor, and graphs are produced of position, velocity and acceleration. The relative phase of each is examined, and compared to theory. Calculations are made for the...
Acceleration
In this lab, students will use motion sensors to represent motion as a change of position in graphical form.
Inertia and the Second Law
A force is applied directly to the cart by pulling and pushing on the attached Force Sensor. The resulting acceleration is measured by the Motion Sensor, and the analysis of a Force vs. Acceleration graph allows the concept of...
Relative Motion in One Dimension
In this lab, students will study motion relative to a moving reference frame.
Velocity and Acceleration
In this lab, students analyze graphs of position and velocity to determine constant velocity and constant acceleration.
Acceleration Due to Gravity
In this lab, students measure the acceleration of a cart moving down an incline, then, compare their measured value to the theoretical.
Relative Motion
In this lab lab, students will use motion sensors to apply the concepts of relative motion and frames of reference to understanding velocity as a vector quantity in one-dimensional motion.
Force and Acceleration
Investigate the relationship between the net force applied to an object and the resulting acceleration of that object. A force is applied to a low friction cart using hanging masses over a pulley.
Work and Energy
In this lab, students will use motion and force sensors to develop an understanding of the work-energy theorem that relates the work done on an object by a net force to the change in the object’s kinetic energy.
