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.

Conservation of Momentum
In this lab, students will use pairs of motion sensors to explore the concept of momentum and its conservation during common types of collisions.
Intro to Measurement
In this lab, students will measure the period of a simple pendulum and use scientific methods to determine the relationships between the period of a pendulum and its length, the mass of the pendulum, and the amplitude of the pendulum’s...
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.
Conservation of Energy
In this lab, students will use motion sensors to detect how energy is transformed in a dynamics system. Students will observe that the total energy of a system is conserved.
Momentum And Impulse
In this lab, students use a motion sensor, force sensor, and dynamics system to investigate the relationship between the change in momentum of a cart undergoing a collision and the impulse imparted to the cart to change its momentum,...
Driven Oscillation of Mass and Spring
The String Vibrator is used to drive the mass and spring, and the resulting oscillation is recorded using the Motion Sensor. The driving frequency is varied to observe the response above, below and at the resonance frequency of...
Collisions in One Dimension
Elastic and inelastic collisions are performed with two dynamics carts of different masses. Magnetic bumpers are used in the elastic collision and Velcro® bumpers are used in the completely inelastic collision. Both the momentum...
Relative Motion in One Dimension
In this lab, students will study motion relative to a moving reference frame.
Magnetic Drag
As a cart moves along an aluminum track, the magnets induce eddy currents in the track, causing magnetic drag on the cart. The magnitude of this force is measured by analyzing the deceleration of the moving cart and the relationship...
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.
Pendulum
In this lab, students will use motion sensors to determine how the mass and length of a simple pendulum affect its period of oscillation.
Newton's First Law
In this lab, students will use motion sensors to determine how force influences the motion of an object. Students will observe that an object’s motion is unchanged in the absence of an external force.
