The Mini Projectile Launcher is for students of force and motion in any Physical Science Classroom. The apparatus is useful in studying projectile range versus angle and conservation of momentum and energy. The launcher will project steel balls at a range of 1 to 2 meters and can be set at various angles from 90 to -45 degrees. The kit is supplied with a trigger release on an extension cable and a clamp to secure it to a table or stand. Two 16mm steel balls are also included. We recommend using the BeeSpi Photogate and Photogate Holder with the Mini Projectile Launcher for instant and direct readings on a digital display.
