Photogates allow for extremely accurate timing of events within physics experiments, for studying free fall, air track collisions, pendulum periods, the speed of a rolling object, among other things. The Vernier Photogate includes an accessory rod for mounting to a ring stand.
The gate has an input port so multiple gates can be connected in a daisy-chain configuration with up to four gates going to a single interface channel.
The laser gate mode requires the addition of a common pen laser, which is directed into the laser port. The laser may be some
