The equipment set for tracing powder patterns is designed for introducing students to the basic kinematics of two-dimensional motion and can be used in conjunction with the pendulum and plotting electrode (1000780) for experiments demonstrating Kepler’s 2nd law of planetary motion or with a pair of elastic spheres and plotting electrode (1000779) for experiments on elastic collisions.
A plotting electrode slides over a plane counterelectrode that is insulated and covered in powdered sulphur. An AC voltage across the two electrodes results in the sulphur powder being attracted or repelled depending on the polarity of the plotting electrode. A trace thus appears in the powder with ridges that are formed at constant intervals of time. The distance between the ridges reflects the speed of the plotting electrode.
