We are bodies in motion, and who cannot help but obey the law or the physics of attraction and repulsion.

我们处在运动状态，这是无法控制的，只有遵循规律,或者引力和斥力的规律。

From one point of view, reading Hobbes, his account of the state of nature seems to derive from his physics of motion and rest, in the opening chapters of Leviathan.

一方面，阅读霍布斯，他关于自然状态的解释似乎,来源于他关于运动和静止的物理学，这也在《利维坦》的开篇章节。

The balance of sodium movement relative to potassium movement changes because there's this resting movement of all these molecules anyway, but that balance changes dramatically when these ion - when these gated ion channels open.

钠钾各自运动始终保持动态的平衡,因为尽管在静息状态,所有这些离子也在运动,但是平衡的剧烈变化,只发生在这些门控离子通道打开的时侯

One way to say it is, every body will continue to remain in a state of rest or uniform motion in a straight line.

另外一种说法是,任何物体都会继续保持静止,或匀速直线运动的状态

It's very clear you don't need a force if something is doing nothing, just sitting there.

显而易见,如果物体没有运动,只是静止状态,那是不需要力的

So the Earth is an inertial frame of reference, if you go in a train relative to the Earth at constant velocity, you're also inertial.

所以,地球是一个惯性参考系,如果你坐在相对于地球匀速运动的火车里,你也处于惯性状态
