我们可以作出,一个简略的估计,估计一下上述加速度有多大0,首先来看,地球自转。

We can try to make an estimate on how large these accelerations are 0 that we experience here in 26.100 and let's start with the one that is due to the earth's rotation.

youdao

因为地球的重力,提供了9。8米/秒2的加速度。

and gravity gives you an acceleration of 9.8 meters per second squared.

youdao

地球也会坠向苹果-，因此地球上的力与地球的质量相等，再乘以地球的加速度。

Well, the earth is going to fall towards the apple — So the force on the earth is the mass of the earth times the acceleration of the earth.

youdao

But there are effects of the Earth's acceleration, which we'll demonstrate.

但地球的加速度还是会产生影响,这一点我们马上就要证明

So, when you divide by m, m cancels and everything falls at the same rate on the surface of the Earth.

因此,当等号两边除以 m 时,m 被消去了,在地球表面的所有物体,都以相同的加速度下落

Right. The most famous example is that when things fall near the surface of the Earth, they all have the same acceleration, and the acceleration that's common is called g, and that's 9.8 m/s^.

最有名的例子就是,当物体地球表面附近下落时,它们都拥有相同的加速度,这个普遍的加速度叫做g,大小为9.8m/s^
