Therefore, when you divide by the mass to get the acceleration, the response of different bodies is inverse to the mass.

因此,当你拿力除以质量得到加速度时,不同物体的加速度与质量成反比

But gravity has a remarkable property that the pull of the Earth is itself proportional to the inertia of the object.

重力有一个显著特征,即地球的引力,与物体的质量成比例

But the acceleration it produces on the elephant and on the mass, are in an inverse ratio of their masses.

但这个力使大象和物体产生的加速度,与它们的质量成反比

If you look at the electrical force, the force of electricity, proton and electron or something, it's not proportional to the mass of either object.

如果你考察电作用力,即电现象产生的力,质子啊,电子啊,或者其它什么东西,这种力不和物体的质量成比例

There's no reason why these two attributes had to be proportional, but they are proportional and they are equal by choice of units and you can ask, "Is this just an accident or is it part of a big picture?"

我们不知道这两个质量为何成比例,但它们确实成比例,而且如果选择合适的单位还会相等,你会问,"这种情况纯属偶然,还是这只是物理学大体系的冰山一角"

This spring is getting squashed on either side, and it'll squash by certain amount x, that depends on your mass, and that x will be turned into a motion of a needle and that'll read your mass.

这个弹簧两边都会受到压缩,压缩量为 x,它由你的质量决定,x 会转换成指针的运动,你从而可以读数
