Pair of Elastic Balls with Plotting Electrode

The Pair of Elastic Balls with Plotting Electrode is a set of two identical plastic balls for experiments on elastic collisions, utilising powder tracing to do so. Each ball features a ball chain for easy suspension. 

Powder Tracing

Powder tracing is a method of tracing the path of objects utilising electrodes and sulphur powder. The plotting electrode slides over an insulated plane counter electrode. This is covered in powdered sulphur, and an AC voltage passes between the two electrodes which causes the sulphur to be attracted or repelled (depending on the polarity of the plotting electrode.

This causes a trace to appear in the sulphur with ridges formed at constant time intervals - the distance between the ridges indicates the plotting electrode's speed.

Dimensions of the Pair of Elastic Balls with Plotting Electrode

  • Diameter: 70mm
  • Weight: 300g
