there is a saying that cats nine lives. A recent study examined why.Scientists carried out astudy of that had out of windows of buildings.Nine out of ten remained alive after afall of two stories or more One cat that fell from the thirty-second floor of abuilding only broke a tooth.Interestingly,the cats were in greatest danger of being killed if they fell from the seventh floor.Falling from either a less or greater height gave then a better chance of survival.
Damage to a body depends on how fast it hits the ground that in turn depends on how far it has fallen,But it's not quite that simple because,as an object falls through the air,the air holds it back and slows the objeed .This is the terminal speed.Bulky things have a lower termial speed there is a larger area for push down harder against the air,Cats have a lower terminal speed than falling people,for exam[le,because they are quite bulky and not very so that they hit the ground more slowly and are less likely to be hurt.
Then what does the seventh floor mater?This is the distance cats task to reach their terminal soeed.After the seventh floor,they may relax and spread out ther legs like a flying squirrel and change their position so that they may land on their feet.This would slow then down and allow their muscles to reduce the force of impact,and thus reduce the damage. 展开
