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.

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。

They both fall with the acceleration g.

他们都以加速度g向下坠落。

Note that GNOME Shell requires 3D acceleration – so be sure that your computer is capable of running it or you’ll enter the ‘fall back’ version of GNOME 3.

注意的是GNOME Shell需要3D加速。 所以确保你的机器适合运行它，否则你要选择GNOME 3的兼容版本。

That's how by either balancing the unknown force with a known force or by simply measuring the acceleration as I fall towards this podium and multiplying by mass, you can find the force that exerts on me.

我们既可以让未知力与已知力平衡,也可以只测量我冲向讲台时加速度的大小,再与我的质量相乘,都能求出作用在我身上的力的大小

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^

Japanese space agency (Jaxa) scientists want to detect a measurable acceleration in the spacecraft as photons - the particles of light - from the Sun fall on the roughly 200-sq-m, ultra-thin sheet.
