This apparatus consists of a curved track with a base at one end. On the base is a support to hold a ball at the proper height for a centre to centre collision with a second ball rolling down the track. The track is level so collision occurs only in the horizontal plane, simplifying calculations.
Consists of
- 25cm one piece track
- 3 balls 12mm diameter
- 2 steel
- 1 glass
- 1 plumb bob
