The Coefficient of Restitution for an one-dimensional collision involving two objects, object A and B, the coefficient of resitution is given by: CR=va-vbua-ubCR=vavbuaub, where:

  • vava = final velocity of object A after impact
  • vbvb = final velocity of object B after impact
  • uaua = initial velocity of object A after impact
  • ubub = initial velocity of object B after impact
