The Science of Hockey
this video is from i take no credit to it and the some of the information gathered

to start off hockey is all about the law of motion, mathematics, and angles "A good slapshot is mostly technique and the power from the weight transfer" the weight of the player is from the core up. when a hockey stick comes in contact with a puck the energy stored in the stick is released into the puck.
Explaining the laws of motion
Newtons first law of motion- Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Newtons second law of motion- The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

Newtons third law of motion- For every action there is an equal and opposite reaction.
hockey players learn to use these laws of motion to understand hockey just a little better and so they can play a little better.
so how do people skate anyways? the friction between the hockey skates to the ice. Hockey players can also reduce the friction between their skates because of a phenomenon known as pressure melting. putting increased pressure on a substance lower its melting point.
