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 to maneuver his 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.
一只从高处下落的猫在停止加速后会将腿伸展成伞形状,这样它与空气的接触面就增大了,于是增大的摩擦力会减缓下落速度。虽然猫有很发达的平衡感,它们还是需要很多时间来调整身体,为四肢着地做好准备。而从较低的高度下落的猫没有时间伸展身体,增加与空气的接触面,从而减速,也没有足够的时间调整好降落的姿势。
