Ballistic (Shock) Pendulum Apparatus

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.
