PIRA 1N30.20 Collisions in One Dimension: 3:1 Collision Balls

• Two steel balls, one with ~2 times the mass of the other are used to show conservation of momentum.
  

• The steel balls collide elastically.
  

• The resulting velocity of small ball when struck by the larger ball is very noticeable.
