Photogates are a staple of every physics lab, used to teach students fundamental concepts about measuring time intervals and calculating speed and acceleration from their measurements. …

Use the Photogate to study free fall, rolling objects, collisions, and pendulums. Photogates allow for extremely accurate timing of events within physics experiments, for studying free fall, air …

Timing Setting for the Photogate is Motion Timing. During operation, times are recorded as leading opaque edges of a "picket fence," bar tape, or a pulley spoke

A photogate is a light sensor that detects the presence or passing of objects and their velocity when they pass through. This detection can trigger a response or action.

Photogates allow for extremely accurate timing of events in various physics experiments including when studying freefall, air track collisions, the speed of a rolling object and pendulum periods.

Get the time at each photogate and the time between each at the same time! Our Digital Timer and Photogates uses an infra-red beam that, when broken, registers a meticulously accurate …

In this project tutorial, we will show you how to create a cheap but accurate photogate (similar to the one pictured below) for use in classroom applications, particularly physics experiments.
