You know that when you hit a baseball high into the air ,it comes down because of gravity .After it hits the ground ,the ball bounces, slow down ,and comes to a stop .Why doesn’t it just keep on rolling ?A force called friction acts on the ball to make it slow down and stop .
1楼的翻译......汗
减速！你一定知道，当你把一个棒球打向空中，他由于重力的作用，会降落下来。当他弹到地上，他会反弹，最后减速，慢慢得停下来。为什么他不是一直保持着滚动呢？有一种力称为摩擦力，作用在球上，使得他减速并且停下。
上面是机器翻译的!
Slow Down !
慢下来
You know that when you hit a baseball high into the air ,
你知道当你把棒球打到很高的空中时
it comes down because of gravity .
因为重力又会降下来
After it hits the ground ,
当它落到地面时
the ball bounces, slow down ,and comes to a stop .
球会弹起,慢慢地会停下来.
Why doesn’t it just keep on rolling ?
为什么它不继续滚动呢?
A force called friction acts on the ball to make it slow down and stop .
是一个叫摩擦力的力作用于它身上,使它慢慢地停下来.
Slow Down !

减速！
大家都知道，将棒球打到高空中之后，球会因为重力作用掉下来。球落地后就会弹跳起来，减速，然后停止。为什么球不会一直滚动呢？因为摩擦力作用在球上，使其减速并停止。
