Collision in Two Dimensions

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
