Using Go Direct Photogate, students are able to easily and accurately measure velocity and acceleration to study the movement of an object in free fall, rolling objects, collisions, and pendulums, without needing to know anything about the geometry of the object.
Go Direct Photogate also includes a single laser gate for use with objects passing outside of the arms of the sensor. Using the laser gate requires a visible-light pen laser (not included).
Go Direct Photogate can be used in a variety of experiments:
Measuring acceleration of a cart on an incline using a cart picket fence
Measuring the angular motion of a wheel as it is turning
Investigating Newton’s second law using a half-Atwood machine to measure acceleration
Determining the time an object passes one or more gates
