英语翻译
Why does a cat that falls from a 50-story building hit the safety net with no more speed than if it?
Question:
Why does a cat that falls from a 50-story building hit the safety net with no more speed than if it fell from the 20th story?
【问题翻译】:为什么一只猫从50层楼掉到安全网上的速度并不比从20层掉到安全网的速度要大?
【Answer】
Because it reaches terminal velocity.
The speed is limited by the air resistance of the object,that means the friction caused by the air will counteract gravity to a certain extent.
In most cases,terminal velocity is reached in a few seconds.
