While that is an interesting topic and well worth investigation, this website focuses on the science behind the game. Specifically, this project will break down various aspects of the sport and delve into the underlying physics.
	"Newton's Third Law of Motion: Every force occurs as one member of an action/reaction pair of forces related to each other." (Knight). More commonly stated, every action has an equal and opposite reaction. This is why in order to generate thrust/movement on the ice, one must first push their skate in a backwards motion to generate a forwards movement. Smooth ice surfaces have hardly any friction. This is beneficial for the skater as this small amount of friction does not incur an overly large loss in velocity. "In 1886 John Joly, an Irish physicist, offered the first scientific explanation for low friction on the ice; when an object -- i.e. an ice skate -- touches the ice surface, the local contact pressure is so high that the ice melts, thereby creating a liquid water layer that lubricates the sliding." (Planck).	https://en.wikipedia.org/wiki/Ice_hockey#/media/File:Capitals-Maple_Leafs_(34075134291).jpg
