Free Falling in Extreme Sports-Bungee Bungee/极限运动中的自由落体运动——蹦极运动
With the continuous development of society, people are always discovering and pursuing all kinds of new things. In order to seek stimulation, a movement beyond the limits of human beings appears in modern times, which is now the most popular "extreme sports".
Extreme sport is the pronoun of "thrill and excitement". Among many extreme sports, besides skydiving at 3000 meters, bungee jumping can be said to be a well-deserved thrill and excitement.
Bungee jumping is an outdoor recreational sport. The enthusiasts need to tie a fixed rubber band to the bare joints at an altitude of 40 meters, and then jump down through the platform.
This motion process is a free falling process. The so-called "free falling" refers to the process in which an object falls from a high place without applying external gravity. The velocity of a free falling body and the density of the object are
proportional to the height of the object.
When bungee jumpers fall freely from high altitudes and approach the ground, the rubber belt pulls people back because of its elasticity. When they reach a certain height, they continue to fall. Then they repeat the process until the elasticity of the rubber belt disappears, and the whole process is officially ended.
Bungee jumping can really be called the second "brave man's game". Many people watch others play bungee jumping crazily and excitedly, but when they stand on the takeoff platform to prepare to jump down, they will be scared back because of the height problem.
Many first-time bungee jumpers were initially frightened to the ground, 40 meters high but 10 stories high, and even a person without heightphobia would have fear at such a high place. But there are also some fearful people who dare to challenge this thrilling and exciting sport.
As an extreme sport, it must be dangerous. At first, some people fell to the ground because the rubber belt was not strong enough to break. Others were hit to the ground because the rubber belt was too long. Others were killed because
the rubber belt was not tied or had not been tied.
Although extreme sports are exciting and interesting, there is a price to pay behind it. There is only one life, let us cherish life, on this basis to challenge the height of life one after another.
Love life, love sports.
人们随着社会地不断发展，总在发现和追求着各种各样的新鲜事物，为了寻求刺激，一种超越人类极限的运动在现代出现，这就是现在最流行的“极限运动”。
极限运动是“惊险、刺激”的代名词，而在众多的极限运动当中，除了3000米的高空跳伞运动之外，“蹦极运动”可以说是当之无愧地惊险与刺激。
蹦极运动属于一种户外休闲运动，参与该项运动的爱好者需要在40米的高空，把一段固定的橡皮带绑在裸关节处，然后通过跳台往下跳。
这个运动过程是一个自由落体的过程，所谓的“自由落体”指的是一个物体在不施加外部重力的情况下从高处落下的过程。自由落体的速度和物体的密度与物体所在的高度成正比。
当蹦极爱好者从高处自由落体快接近地面的时候，橡皮带会因为弹力的关系把人往回拉，当达到一定的高度的时候继续往下落，然后接下来会重复这个过程，直到橡皮带的弹力消失为止，整个运动过程才正式结束。
蹦极运动真的可以称得上是第二个“勇敢者的游戏”，很多人看着别人玩蹦极运动非常疯狂刺激，但是当自己站在起跳台上要准备向下跳的时候却会因为高度的问题吓得退后。
很多第一次尝试蹦极运动的挑战者最初都被吓得瘫在地上，40米的高度可是10层楼的高度，即使是一个没有恐高症的人在这么高的地方也会产生恐惧。但是也不乏一些不怕的人，他们勇于挑战这一惊险而刺激的运动。
作为极限运动肯定是具有一定的危险性的，当初就有人因为橡皮带不够结实断裂后摔落在地致死，也有人因为橡皮带太长直接被狠狠地砸到地上致死，更有人因为橡皮带没有绑好或者还没绑橡皮带直接从40米高空坠落致死的。
极限运动虽然惊险刺激有趣，但是在这背后都是需要付出一定代价的。生命只有一次，请让我们珍爱生命，在此基础上去挑战人生一个又一个的高度。
热爱生活，热爱体育运动。
