Checking in hockey is a great example of collisions. According to  Physics: a strategic approach by Randall D. Knight, Newton's second  law, F=ma, applies directly to checking in hockey. The force a player  has when hitting another player directly relates to their speed and mass.  When some one is hit in this manner(see right) it creates an elastic  collision where the two masses are bouncing off of each other. Of   course, there are there are other variables that apply, such as a   players center of gravity, balance, and where a player gets hit.

Along with elastic collisions, there are also inelastic  collisions in checking form(see right). According to Physics: a  strategic approach by Randall D. Knight, an inelastic collision  is, "A collision in which the two objects stick together and move  with a common final velocity." The gif to the right is a good  example of this. The player in the red had a greater force when  interacting with the player in the white, so he overpowers the  player in the white, forcing him to go in the direction and speed  of the player in the red.
