While physics can be found in every sport, hockey is a big one. Force, velocity, gravity, and friction are all components of the sport.
For example, when a player skates up to the puck to make a slapshot, they have to take into consideration that when the stick comes into contact with the puck, the force of the stick will launch the puck at an angle. The desired angle would be the angle that brings the puck into the goal. The player doesn't want the puck to go over the net, so they must shoot the puck with an angle and a large enough force that will send the puck into the goal.
In addition, friction is another example of physics in hockey. When a player shoots the puck down the rink towards the goal, the puck will not go on forever. The ice is slippery enough to make the puck go far enough, but realistically would stop if the rink was large enough. This is also determined by how hard the player shoots the puck.
Lastly, when the Sabres are playing and they are losing, the theory that "objects in motion stay in motion unless acted upon by an outside force" applies as the pillow that I threw stops moving when it hits the TV.
