The Time of Flight Pad is designed for used with the Go Direct Projectile Launcher or the Vernier Projectile Launcher and is used to determine the time the projectile is in flight, along with the launch speed of a projectile reported by the launcher.

The Time of Flight Pad can also be used with photogates as a standalone sensor or daisy-chained to a Go Direct Photogate using an Go Direct Time of Flight Pad accessory cable (not included).

Time-of-flight measurements allow students to see just how kinematic calculations work in real-world applications.
