Two-dimension collision apparatus

A steel ball rolls down a track to finally fall freely, leaving a trace on the fall plane thanks to a carbon-paper sheet.
It is possible to do calculations on energy conservation and on motion composition by changing the free fall height and by measuring the range.
With two balls, it is also possible to verify the conservation of the motion quantity and of the kinetic energy.
The item is supplied with 3 steel balls.
Dimensions: 400x100x20 mm.
