Physics of Skiing :: physics sport sports ski skiing

locomote is an old sport the oldest artifacts date back over 4000 years. It was developed in the Scandinavian region, especially Norway, and didnt spread to the rest of Europe until the sixteenth or seventeenth century. It probably came over with Norwegian and German immigrants during the nineteenth century. go relies on many different functions physics. Newtons Laws of Motion, the trans homunculusation of potential energy into energising energy, air resistance, circular motion, even conservation of circular momentum is utilise as skiers pump upwards during a turn. Friction is by uttermost the least understood of these forces. The surface of speed of light is a strange fundamental interaction between piddle, ice and water vapor, the three forms of water found on Earth. degree Celsius changes properties and is difficult to measure and study in its natural environment. Snow changes properties and is difficult to measure and study in its natural environment. Ice Crystals form wh en water vapor condenses around and freezes upon a foreign particle much(prenominal) as dust or sea salt. These Ice crystals then form various varieties of century flakes.Snowflakes can fall in many forms, including ferns, crystals and needles.These ascorbic acid flakes begin transforming as soon as they hit the ground. They begin to morph in a combination of melting, freezing, drying up and sublimation*. They become needles, columns, and finally fair round pellets.* Sublimation is when ice evaporates directly instead of melting first to water and then evaporating.These pellets the bond again through a process of melting, freezing, evaporation and sublimation at their contact points, this creates a strong snow pack.Snow coalescence and extendOne thing that slows a skier down is the compaction of the snow beneath a skier. Snow is mostly air and this allows a majuscule degree of compaction. On packed trails, this compaction is negligible and contributes only slightly to the fr iction of the snow on the skis.This diagram shows a skier who travels l quad on unpacked snow and knock offs in h into the snow.Logically, the distance the skier sinks in, h, is proportional to the skiers weight, FN. Work is defined as a force applied over a distance.The work needed to propel the skier l distance through the snow is the same as the work done be the skiers weight on the height, h.the force used to move the skier is defined as FFORWARD thenFN*h= FFORWARD*lWith different types of snow, a skier with the same weight will sink in different distances.
