貓有九命嗎
[ 2008-02-03 16:36 ]

人們常說貓有九命,果真如此嗎?一只貓從很高的樓上掉下來,多半都能安然無恙,讓你不得不相信它真的有那么多命。那么,事實果真如此嗎?讓我們一起來探索一下吧!

Some people believe in the superstition that cats have nine lives, because cats can survive falls from high places with few, if any injuries. This gives the appearance that the cats return to life after sustaining a fatal accident. Granted, they may sustain minor injuries, such as bloody noses, cracked teeth, or a few broken ribs, but they live to recover.

The ability of the cat to survive these accidents that would kill humans or other animals is not due to multiple lives, but to several advantages they possess. Their small size and low body weight soften the impact as they make contact with the ground after falling from great heights.

The highly developed inner ears of cats equip them with an unusually keen sense of balance, which is critical to their landing on their feet. This sense of balance allows a cat falling upside down to right himself by rapidly determining his position, repositioning himself, and making any adjustments necessary to ensure that he lands on all fours.

Since cats land on all four paws, the impact from landing on the ground is absorbed by all four. Additionally, cats bend their legs when they land, which cushions the impact by spreading the impact, not only through bones that could easily break, but through the joints and muscles as well.

Most are surprised to learn that a cat stands a greater chance of survival if it falls from a higher place than from a lower place. New Yorkveterinariansgathered data from theirfelinepatients, which clearly support this fact. Ten percent of their patients died after falling from 2-6 stories, while only five percent of the fatalities occurred when their patients fell from 7-32 stories.

Laws of physics explain why these survival rates vary. All falling bodies, regardless of their masses, accelerate by 22 miles per hour per second of their falls. The falling object, after traveling a certain distance through the air reaches a final speed, or "terminalvelocity," because the object's friction with the air slows the fall. The smaller the object's mass, and the greater its area, the more it will slow.
A cat falling from a higher floor, after it stops accelerating, spreads its legs into an umbrella shape, which increases the area against which the air must push and increases the friction, thus slowing the cat's fall. Through the cats highly developed sense of balance, he buys more time tomaneuverhis body in preparation for landing on all fours. A cat falling from a lower height does not have the opportunity to increase its body's area, slow its fall, or position his body to land on all four feet.
