The Physics of Hockey Essays - 1344 Words

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 (Hachà © 37). The†¦show more content†¦This does not mean that there is more heat but rather heat is applied more quickly (Hachà © 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. â€Å"Gravity pulls down on a hockey players 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 (Hachà © 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 =  ½Show MoreRelatedPhysics Of The Field Of Medicine1381 Words   |  6 PagesThe study of physics over the last year has been intriguing and extremely valuable to my education to pursuer a career in the field of medicine. Learning physics in the classroom is one thing, but being able to apply it to everyday scenarios is what has made this course so interesting compared to other various science courses offered at Gonzaga. When I was three years old my parents bought me my first pair of hockey skates and since then hockey has consumed my entire life.

This is true from the way we communicate to the way that we fight wars. In some cases the influence of the laws of physics on our world are extremely apparent, such as in sports. Basketball, hockey, baseball and even cricket involve physics. From the most basic motions players perform in the game, to different plays designed by coaches, physics touches it all. These appearances of physicsRead MoreEssay on Mkt521 Case Swans696 Words   |  3 PagesArena is an ongoing hockey style arena in a city of 450,000 people. David Swan the owner wants to increase profits by reaching public skaters outside the hockey and figure skating format. Using only what information can be obtained from counting customers and reading industry newsletters Mr. Swan, has made investments in equipment and promotions. To date the returns on investment have been disappointing.

Two years of A-level preparation, further solidified my interest in this area as I found myself very fond of learning mathematics, physics and mechanics in particular. In addition, my curiosity in the operation and dynamics of objects naturally influences my choice of degree, leading me towards Engineering as i t is a discipline which satisfy my own interest and most probably bring outRead MoreBiography of Niels Bohr, The Danish Physicist Essay1120 Words   |  5 Pagesoutdated but is still known as the best model of atoms, and is still used in high school physics and chemistry. Bohr soon realized that he did not enjoy teaching the medical students. He decided to return to Manchester, where Rutherford had offered him a job as a reader in Darwin’s place, whose contract had expired, Bohr accepted. In April 1917, Bohr began a campaign to establish an institute of Theoretical Physics. He gained the support of Danish government and Carlsberg Foundation, establishing theRead MoreEssay about The Physic of Paintball1567 Words   |  7 PagesThe Physic of Paintball I.The Fundamentals of the Game of Paintball. Paintball is a sport that is still fairly new in the world being not much more that a decade old. This game as with other sports would not be possible without physics. Physics is essential to the game of paintball. Some of physics that are involved in paintball are pressurized gas, projectile motion, and the impulse of being hit by a paintball. As with all sports there is necessary equipment needed to play. The mostRead MoreUntil I Was Dying, I Was Not Living.
