The sport of skiing has been around for thousands of years, originally existing solely as a form of transportation. Today the sport is entirely dependent upon the laws of physics, and has even had advancements through reliance on physics. There are two types of Nordic Skiing. These are Classic (or diagonal) and Skate Skiing. Usually these two forms are raced separate. To be fair, there are actually two slightly different forms of skate skiing; V1 and V2. As these can get very very complicated and precise in the technique, I will focus mainly on classic skiing, which is also the type of skiing that most people are familiar with.
Cross-Country Skiing is the most basic form of skiing, even preceding downhill skiing. Primitive skis may have even been used about 3000 B.C. in Norway. There have been cave drawing found that seem to depict men on skis. Skiing has its roots in Scandinavia; Vikings used skis as a form of transportation in the 10th century A.D.
Early skis were made of wood, and even the word ski comes from the Norse word skith a stick of wood. Norse skies were very rudimentary, little more than snowshoes. Glide was little to none. It was not until the early 1800s when Sondre Norheim changed the face of skiing and gave skis glide that the sport was introduced to the world.
Competitive skiing started in the late 1800s, again in Norway. In the 1932 Winter Olympics at Lake Placid, Nordic Skiing as we know it was added. Today the sport has evolved to be both extremely competitive and leisurely.
In the past 30 years the sport has changed dramatically, adding skis made of synthetic materials, and utilizing waxes for improved speed. Physicists have been at the front line of all this; from determining the coefficent of friction for both the wax and the ski, to helping skiers change their technique based on the laws of physics.
To maximize speed, Nordic skiing is more about form than probably any other sport. Brute strength and athletic prowess certainly have their advantages, but these pale in comparision to proper technique.
While the shape of classic skis is slightly different than that of skate skis, the real difference is that classic skis have a "kick zone." This is a spot directly underneath the foot that has kick wax applied to it. Kick wax is a sticky poly-hydrocarbon that in theory is only supposed to provide a sticky surface from which to push back from.
The Physics Related to Snowboarding The last thing that goes through your mind when speeding down a mountain on a snowboard is all the physics involved with snowboarding, from the time you get on the chair lift, until the time you come to a rest at the bottom of the mountain. Now let’s take a look at all of the physics that are related to snowboarding. Gravity is the force that keeps you on the ground. Without gravity, snowboarding would not be the same.
Whether zipping along a winding trail, flying through the open flats, or powering up a steep hill, snow machines and the rider need to use physics to stay in control of the machine and themselves. The main components are the track, engine, skis and riding. Snowmachine tracks are essential to making a snowmachine move. Ever since snow machines first originated in the late 50's, designers have been finding ways to improve traction in a variety of conditions. Some of these conditions are driving on groomed trails, not groomed trails, overflow, and deep snow.
Another type of wax is applied to the "kicker". The kicker is the area under the bindings. In other words the kicker is the area where most of the gravitational force of the skier is applied. Skiers apply a type of wax to the kicker that will cause the friction coefficient to increase. This allows skiers to be able to push off and ski uphill.
Snowmobiles have come a long way since Polaris Industries created the first one. Ski Doo always on its tale trying to defeat the one sled company that will always be around. I Know that a stock Polaris and a stock Ski doo raced, that the Polaris would win every time. That is the reason why I ride Polaris, because no matter where you are they’re the way out!
Next, take a few steps up a slight incline with your front foot in the snowboard binding and your back foot out. Make sure that the snowboard is perpendicular to the incline. Take one step with your foot that is not attached to the snowboard, then lift your foot with the snowboard attached to it and take a step with the entire snowboard. Keep taking baby steps until you are up an incline. The process can become tiring after a while, but for beginners the ski-lift is not quite recommended at this point. You should be looking for beginner slopes with a very small incline.
Snowboarding was invented as early as the year 1963, when Tom Sims created a snowboard in his shop class in seventh-grade. He was a pioneer in the sport and
In snowboard as in any other sport the athlete has to be thinking at all times, analyzing the situation that surrounds you, make split decisions, and even perform quick calculations in your head.
If anyone has ever heard about or watched skiing it is probably alpine skiing. Alpine skiing is the most traditional and popular type of skiing. Some of the necessary pieces of equipment needed for skiing are, helmet, gloves, ski pants and jacket, goggles, ski poles, ski boots and bindings, and last but not least skis. There are ten alpine skiing events in the olympics they vary from Downhill and Slalom, to Moguls and Slopestyle. Alpine skiing has been around since about 600 BC in modern day China. Earlier skiers used one big pole or spear not two like modern day skiers. Until the mid 19th century skiing was only used for transportation, but since then it is mainly used as a recreational sport.
Gymnasts use physics everyday. As a gymnast I never realized how much physics went into every motion, every back handspring, every mistake on the bars. If gymnasts were physicists (or at least knew more about physics) they would be better equipped to handle the difficult aspects of gymnastics. As a gymnast I learned the motions that were necessary to complete the tricks that I was working on, and as a coach I taught others the same. I never truly understood why a particular angle gave me a better back handspring or why the angle that I hit a springboard at really mattered when completing a vault. We are going to explore some of the different apparatuses in gymnastics and a few of the physics laws that are involved in them. We will not even barely scratch the surface of the different ways that physics can explain gymnastics.
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 boot of the skate is hard enough to protect the foot from puck impact but also flexible enough “to allow the calf muscle to push forward and to ease knee bending when the player crouches” (Haché 35).
Pieter and I were determined to become proficient water skiers, while Rhea had knee issues that limited her participation. The Gibson Girl only had a forty horsepower motor, which wasn’t sufficient power for faster skiing or for doing tricks like skiing barefoot. I remember using the Comfort for some of our skiing before Dad traded the outboard for a sixteen-foot Gar Wood Junior, which had an inboard motor and more power. Pieter and I spent hours practicing the basics of getting up efficiently, skiing across the wake and then jumping the wake. It wasn’t long before we developed a passion for mastering slalom skiing. I wanted to ski all the time during that period.
Reindeer racing usually takes place at a festival. One of the biggest festivals is in Jokkmokk, Sweden. This is called the Jokkmokk Winter Market. It happens every year during the first week of February. The Jokkmokk Winter Market is very old. It has taken place for over four hundred years. It draws tourists from around the world. Folk dancing and singing are popular events. There's even a reindeer
Skiing, as a sport has existed since the early 1800’s, although depictions of skis have been discovered throughout Europe dating back thousands of years. Skiing as a recreational activity became popularized in the mid 1800’s however it did not arrive in the United States until around 1841. Once the concept of skiing reached the states, it took off. The United States continued to power advances in skiing for decades, with the introduction of rope tows, then actual ski lifts. By the 1950’s several ski areas had begun snowmaking and trail grooming, two American born inovatio9ns which ensured better skiing conditions and launched the US far ahead of Europe in ski technology (Fry 38). Skiing continued to evolve throughout the 1900’s, constantly changing and adapting to improve athlete performance and recreational experiences. Skis and equipment changed quickly and frequently, ski bindings, which...
Speed Skating has been around for a while now. This specific sport has many different techniquies, and skills. There is a lot more to skating then putting on shoes that have wheels and going on a wood floor skating around in circles.
Challenge plays an essential role in defining a sport; it provides the individual with the feeling of achievement in success. Skiing poses challenge even in its simplest foundations. Skiing on a poor quality hill, with icy snow and poor upkeep can sometimes create more challenge than a well-groomed slope. Skiing in the backcountry away from lifts and other people in freshly fallen snow provides an opportunity for the best of skiers to test t...
