Physics can be seen in Hockey in multiple ways. The main concept would be the friction between the players skates and the ice. Ice is not a frictionless surface therefore friction is involved. On the reference table rubber on ice has a coefficient of friction when moving of 0.15. When calcualting friction this must be inculded. Hockey can become a very physical game. When pushing another player into the boards, a huge force must be transfered from one person to the other also inculding the force of friction.
