Photogate

The Vernier Photogate can be used to study free fall, rolling objects, collisions and pendulums. The photogate has a built-in laser detector, so you can use a laser to create a photogate you could drive a truck through. You can also connect up to four gates in a chain. The Vernier Photogate comes with an accessory rod for attachment to a ring stand or for adding the Ultra Pulley Attachment.

Laser Pointer

This Class IIIa (<5 rnW) laser pointer can be used with the Vernier Photogate to produce a gate that is wider than the normal 7.5 cm spacing, making it possible to measure the speed of an automobile or of a person running. The laser case is made of aircraft aluminum, and it uses two AAA batteries (included). The wavelength of the light is 650 nm.
