The Beijing Winter Olympics have been open for a week, and various wonderful events have been unveiled in turn, making people fully feel the charm of ice and snow sports. If you find a key word for ice and snow sports, many people will blurt out - "fast". Because the friction of the ice surface and snow surface is very small, the speed project carried out on it will naturally "ice and snow gallop". Which event in the Winter Olympics is the fastest? Let's compare.
The conversion of gravitational potential energy at height into kinetic energy of velocity, an acceleration process from high to low, is something we all learned in physics classes. With this principle in mind, ski jumping can reach speeds of up to 90 km/h. Taking off is the key to achieving aerial speed, and the quality of the jump determines the athlete's performance. When the athlete slides to the springboard at the end of the platform at a speed of more than 25 meters per second, he jumps upwards and his body flies into the air at high speed.
On February 10, China's Zhang Yangming competed in the men's all-around alpine skiing competition at the Beijing Winter Olympics.
Known as the "crown jewel of the Winter Olympics", alpine skiing can reach speeds of 125 kilometers per hour. Athletes swoop down from an altitude of more than 800 meters, and the average slope of the snow surface reaches 15-30 degrees. During the glide, the athletes are almost fully catniped, and when they encounter slope fluctuations, they will take off in the air and fly parallel to the ground for a period of time. Alpine skiing is one of the most demanding sports for the body, not to mention friends with fear of heights, ordinary people estimate that once they stand at the starting point, their legs will be soft, and athletes need strong will and physical strength to complete this project.
On February 7, 2022, Chinese alpine skier Xu Mingfu crossed the finish line of the men's downhill competition at the Beijing Winter Olympics, becoming the first Chinese athlete in history to participate in the winter olympic downhill competition and finish the race. When Xu Mingfu finished the men's downhill competition, IOC President Bach also gave him a signed watch, hoping that he would work harder in the future games.
The ice surface is more slippery than the snow surface, and the "king of speed" can compete for the "king of speed" are all sliding events, first of all, the third-ranked steel frame snowmobile, which can reach a speed of 130 kilometers per hour; the second is the sled, the start of the sled is a sitting posture, with the power of the hand as the starting force, its top speed can reach 140 kilometers per hour; the speed king of the Winter Olympics is the snowmobile known as the ice F1, which can reach a maximum speed of 150 kilometers per hour, which is much higher than the speed limit of 120 kilometers per hour on the highway.
The timing of the snowmobile event is measured in thousandths of a second, and the snowmobile during the sprint can advance about 4 centimeters in such a small unit of time. The high-speed progress of the snowmobile project makes people often nervous and hold their breath when watching the race.
