The Physics of Hockey

Physics is everywhere. Consequently, physics is a part of sports and more specifically, hockey. As the scientific discoveries progressed with time, so did the advancements in the sport of hockey, reflecting on how important and influential science truly is. Physics takes part in the ice, the skates, the protective gear, the shots, goaltending, and all other aspects of ice hockey. Skates used to be more like skis. Players glided on the ice rather than actually skated. Artifacts also show the use of animal bones as skate blades as well. Currently, steal blades are used. There is a small arc groove on the blade that provides the friction needed to counteract the slipperiness of the ice (Haché 37). The…show more content…

This does not mean that there is more heat but rather heat is applied more quickly (Haché 24).

The most basic and necessary skill in hockey is skating. Skating is made possible thanks to Newton’s Third Law. With every action there is an equal and opposite reaction. The blade applies force on the ice and the ice pushes back on the blade causing a forward movement. To accelerate, players exert a strong force on the lower part of their bodies by leaning forward. “Gravity pulls down on a hockey player's center of mass which ‘torques’ him forward” (Exploratorium 1). Skaters also skate and accelerate while turning. Centripetal force enables the player to lean inward and create a sharp turn (Haché 50).

Acceleration is negative for a braking skater and is determined by the friction force on the skate blade. To achieve this, the skater turns their skates perpendicular to the direction of motion and digs the blade into the ice, creating the greatest resistive force. The blade scrapes a layer of ice off the surface and the player comes to a stop (Exploratorium 1).

Another large part of the sport is the physical contact. Hockey can turn into a brutal game with 220 pound men checking each other left and right. Because these men have large masses and fast velocities, they have a lot of kinetic energy. The energy of each player before the collision is K = ½ mv2 and afterward (because their collisions are inelastic) their total energy = ½

It doesn't take a sports expert to determine that one major difference between ice hockey and field hockey is the surface on which the games are played. The differences, however, go beyond the playing surface and may not be so obvious to the uninitiated hockey fan.

Origins. The Loudon Field Hockey Association claims that the origins of field hockey can be traced back 4,000 years, as evidenced by drawings on an ancient tomb in the Nile Valley. Evidence exists that shows ancient Aztecs, Greeks and Romans played similar forms of the game. The modern game of field hockey came to fruition in the mid-19th century in Great Britain. The British army brought the game to its colonies, and the first international competition took place in 1895. The first official ice hockey rules were established on the other side of the Atlantic in Montreal in 1877, with the first official league established just over a decade later.

Participants. Ice hockey uses six players per team at a time: three forwards, two defensemen and a goalie. Field hockey uses 11 players: five forwards, three halves, two backs and a goalie. Field hockey formations and team sizes vary depending on the level of play and coaching strategy. Field hockey is played in more than 70 nations around the world and has yet to attain the popularity of ice hockey.

Equipment. The basic objective of each game is the same: Shoot an object into the opponent's net. The device used to shoot the object, the object itself and the nets, however, differ. A field hockey goal consists of two 7-foot high posts spaced 12 feet apart. An ice hockey goal stands 4 feet high and 6 feet wide. Field hockey uses a ball; ice hockey uses a puck. Both sports use curved sticks of differing strength to strike the object. Because of the physical element in ice hockey — body checking, for example — ice hockey players wear much more equipment. The hardness of an ice hockey puck and the increased speed involved with ice skates over shoes make ice hockey a faster-paced sport.

Time and place. An ice hockey game consists of three 20-minute periods and is played on an ice-covered surface of varying sizes. A field hockey game consists of two 35-minute halves and is played on a 60-by-100-yard grass field.

Despite the similarity in names and objectives, no one who has ever watched the two sports would ever confuse them.
