Collision Example: This illustrates the example problem in which one mass collides into another mass that is initially stationary.
So, before the collision, we calculate the momentum of two objects by adding their individual momentum.
An ice hockey goalie catches a hockey puck and recoils backward.
If you know the velocity of one object after the collision, you can determine the other see.
Alternatively, stored energy may be converted into internal kinetic energy during a collision.
