Its gate features an input port, so multi- ple gates can be con- nected in a daisy-chain configuration with up to four gates going to a single interface channel. The Vernier Photogate also sup- ports auto-ID with compatible software. Use the unit to study free fall, air track collisions, pendulum periods, the speed of a rolling object, and much more.

WLS-1807-76 Motion Detector Study the motion of a person walking, a ball in free fall, a cart on a ramp, and much more. Using ultrasound to meas- ure distance, the motion detector emits pulses, which are reflected from a target, and then detected by the device. The time it takes for the reflected pulses to return is then used to calculate position, velocity, and acceleration. The detector can measure objects within a range of 15 cm to 6 m. The short minimum target distance allows objects to be closer to the detector and reduces stray reflections. A spe- cial track mode also tailors the sensitivity for dynamics carts on tracks for lower noise and higher quality data.
