This classroom-quailty experimental apparatus is excellent for demonstrating the Law of Conservation of Momentum and Trajectory. The unit uses a nylon pendulum with a tapered rubber insert. Both the pendulum and the base have leveling screws. The spring-loaded gun has a self-locking trigger and rubber bumper to prevent damage on impact. The scale is marked in degrees and is registered by a counter-weighted needle that remains in place at the height of the arc. Instructions provided. Measures 16-1/2" x14" x15" and weighs 4.75 lb.
