  2. ...will be minimum. Conversely, if the 2 objects stick together after the collision , the loss in K.E. is maximum, because this is the only possible situation...

  3. ... with elastic collision and inelastic collision . In elastic collision ,the kinetic enery is ... 2 answer in K.E. formula. In inelastic collision case, you will find that both answers...

  4. ...you are asking how to let the initial and final kinetic energy be equal. In an elastic collision , we can use a air track so that the friction is highly reduced . ...

  5. a. In a collision , momentum is conserved when there is no..., the velocity of A relative to B before the collision is 4.21 m/s in the direction of N61.6*W. ii. As the collision ...

  6. elastic collision : collision in which there is no loss of kinetic energy of the system. inelastic collision : collision ... collision : process in which the collided objects stick together after the collision . Note that in all three collision processes, momentum of the system is always ...

  7. ...formula for specific situations. The most important concepts in collision are: 1. law of conservation of momentum(動量守衡) 2. law of conservation of kinetic...
