Physics is everywhere in hockey, from how the players speed up, to how the ice has a low frictional coefficient, so everything slides. The skates are sharpened so that there is a smaller area of contact between the skates and the ice, so that when the skater tries to turn, the smaller contact area focuses the force of the skater into the ice, giving them more turning power. The puck is also governed by physics. Every time it is hit, since the ice has a near 0 coefficient of friction, it doesn't really slow down at all. When the puck is in the air is is accelerating at -9.8m/s^2 in the up and down direction. When the player wants to speed up, he uses the sharp edge of the skate to dig into the ice, which then gives him a place to push off of. Depending on which way his skates are pointing, the motion can be described by using vectors. Basically, everything in hockey is physics.
