Physics of Skiing :: physics sport sports ski skiing
Skiing is an old blow the oldest artifacts date back over 4000 years. It was developed in the Scandinavian region, particularly Norway, and didnt spread to the rest of Europe until the sixteenth or seventeenth century. It believably came over with Norwegian and German immigrants during the nineteenth century.Skiing relies on legion(predicate) distinguishable forms physics. Newtons Laws of Motion, the transformation of potential energy into kinetic energy, air resistance, peak motion, even conservation of circular momentum is use as skiers heart and soul upwards during a turn. Friction is by far the least mum of these forces. The surface of beguile is a strange interaction between water, scum and water vaporization, the three forms of water found on Earth. Snow changes properties and is hard-fought to valuate and study in its natural environment. Snow changes properties and is difficult to measure and study in its natural environment. Ice Crystals form when water vapor co ndenses around and freezes upon a foreign particle such as form or sea salt. These Ice crystals then form various varieties of one C flakes.Snowflakes can fall in many forms, including ferns, crystals and needles.These one C flakes begin transforming as soon as they hit the ground. They begin to morph in a combination of melting, freezing, evaporation and sublimation*. They become needles, columns, and finally simple round pellets.* Sublimation is when methamphetamine evaporates directly instead of melting first to water and then evaporating.These pellets the trammel again through a process of melting, freezing, evaporation and sublimation at their assemble points, this creates a strong snow pack.Snow Compaction and Work oneness thing that slows a skier down is the compaction of the snow beneath a skier. Snow is mostly air and this allows a great degree of compaction. On packed trails, this compaction is negligible and contributes only slightly to the friction of the snow on t he skis.This diagram shows a skier who travels l distance on unpacked snow and sinks 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 compulsory to propel the skier l distance through the snow is the same as the work done be the skiers weight along the height, h.the force used to move the skier is defined as FFORWARD thenFN*h= FFORWARD*lWith several(predicate) types of snow, a skier with the same weight will sink in different distances.
