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。
Typical Applications
· Study motion at a constant speed
· Measure a freely falling object
· Study kinematics on an inclined plane
· Measure speed of a projectile
· Measure acceleration of a cart
