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.
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.

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.

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.
In this lab, students will generate graphs of position and velocity for a cart accelerating down an incline. Then, they'll compare their user-defined curve fits to the standard equations of motion.
Newton's Second Law is examined by measuring the resulting acceleration of a fan cart under two conditions: Variable force (while keeping the mass constant) and variable mass (while keeping the force constant).
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.
To investigate Newton's Third Law, the forces are examined that are exerted on the two sensors by a connecting string. Also, the external force exerted by hand on an elastic cord is compared to the internal forces created by the...
In this lab, students will investigate the relationship between position and velocity using a Motion Sensor to measure the position of a motorized cart.
