Product Guides
Photogates, Fences, and Timers
Photogates, fences, and timers are a staple of every physics lab. We’ve developed two standalone photogates, as well as two software-dependent options with varying capabilities and applications. This page compares our products’ functions, applications, and connectivity to help you select the perfect fit for your lab.
Experiment Library
Perform the following experiments and more with the Photogate Head.
Visit PASCO's Experiment Library to view more activities.
Instantaneous and Average Speed
In this lab, students will measure a cart's average speed between photogates to observe the difference between instantaneous and average speed.
Freefall Picket Fence
In this lab, students generate velocity vs. time graph for a picket fence free-falling through a Photogate. Then, students will use their graphs to determine the acceleration due to gravity.
Projectile Motion
Use photogates to measure time of flight and the initial launch velocity of the ball and predict the range fired at an angle off the table onto the floor. Also, find the maximum range as a function of angle.
Projectile Motion EX-5502
The purpose of this experiment is to predict the horizontal range of a projectile shot from various heights and angles. In addition, students will compare the time of flight for projectiles shot horizontally at different muzzle...
Atwood's Machine
Using an Atwood’s Machine, a photogate is used to measure the velocity of both masses as one moves up and the other moves down. The slope of the graph of velocity vs. time is the acceleration of the system and compensation is...
