田径运动中也有科学规律可循,凡是懂得并善于利用这个规律的教练、运动员,就有可能夺金牌。科氏加速度在田径赛跑及速度滑冰200米以上竞赛项目中,运动员都是沿环形跑道逆时针方向前进的,这是什么原因呢?如果你在洗脸池里存放一池水,那么当你把栓塞拔起,水流总是按逆时针方向流出,这一现象并非偶然,它与地球自转密切相关。由于地球自转,流向排水孔的水流按科氏(即:科里奥利效应)加速度指向左侧,这就形成了水流的逆时针方向旋转。同理,运动员在跑道上逆时针奋进,也恰好顺应了地球自转的科氏加速度方向跑,这样不仅省力,而且速度更快。当然,在南半球,逆时针方向的结果正好相反,就不能起到提高竞赛成绩作用,这也是科氏加速度原理的逆效应。
Track and field sports also have scientific rules to follow, all who know and are good at using this law coaches, athletes, it is possible to win the gold medal. Coriolis Acceleration In athletics and speed skating more than 200 meters race, the athletes are all moving anticlockwise along the circular runway. What is the reason? If you keep a pool of water in the washbasin, It is not by chance that water flows always counterclockwise, and it is closely related to the Earth’s rotation. Due to Earth’s rotation, the water flow to the drain hole points to the left with Coriolis (ie, Coriolis effect) acceleration, which creates a counter-clockwise rotation of the water flow. By the same token, athletes advance counter-clockwise on the runway and also follow the Coriolis acceleration direction of the Earth’s rotation, which is not only labor-saving but also faster. Of course, in the southern hemisphere, the counterclockwise result is the opposite, which can not play the role of improving race performance. This is also the inverse effect of Coriolis acceleration principle.
