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.

Great Race
In this lab, students will race the Fan Cart and Motorized Cart.The Fan Cart gets off to a slow start, but has a constant acceleration. The Motorized Cart has a constant speed and initially pulls out ahead. But what determines...
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.
Speed and Velocity
In this lab, students will make predictions about how a cart's speed and velocity differ. Then, they'll test their predictions using motion sensors.
Spring and Mass Oscillations
A Motion Sensor measures the position of the oscillating mass, and the Force Sensor is used to determine the spring constant. The period of oscillation is measured, and compared to the theoretical value.
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.
Coefficients Of Friction
In this lab, students use a motion sensor and a force sensor to determine the static and kinetic friction coefficients between two contacting surfaces.
Newton's Second Law
In this lab, students will use force and motion sensors to study the relationship between the net force applied to an object, the acceleration of the object, and the object's mass.
Newton's Second Law
In this lab, students use a motion sensor to determine the relationship between a system’s mass, acceleration, and the net force being applied to the system.
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,...
Acceleration
In this lab, students will use motion sensors to represent motion as a change of position in graphical form.
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.
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.
