Cylindrical pendulum bob with sliding plotter electrode for experiments to confirm Kepler's law governing areas covered by a body subject to a central force that can be demonstrated by means of powder tracing. Steel, with metal ball chain ... еще

A very light acrylic puck for demonstrating collisions between very unequal masses. A steel puck is scarcely deflected after a collision with the acrylic puck. еще

A 7.5 cm diameter, 210 g aluminum puck for demonstrating collisions between unequal masses. The aluminum puck deflects a steel puck less than a steel puck but more than the acrylic puck. еще

Pair of balls with identical mass and sliding plotter electrode for experiments on elastic collisions that can be demonstrated by means of powder tracing. Made of red plastic with metal ball chain. еще
