Photogate and Pulley System

SKU: ME-6838A Category: Tag:



The Photogate/Pulley System uses a photogate head to monitor low-friction
pulley rotation, providing a simple, versatile sensor. Calculate and graph
position, velocity, acceleration of carts, masses, etc. The Photogate/Pulley
System can perform all the functions of the discontinued Smart Pulley. Additionally, the
pulley can be removed, and the photogate can be used to perform photogate
experiments. The Photogate/Pulley System can be used with the Smart Timer, ScienceWorshop interfaces, and PASPORT interfaces with the Digital Adapter.
