惯性定律

In this paper it is explained that the law of conservation of mechanical energy must Obey the relativity principle of mechanics.

文章系统地阐明了机械能守恒定律无条件服从力学相对性原理，若总机械能在一个惯性系守恒，它就在所有惯性系守恒。

Usually set up Newton's first law of inertial frame of reference as a frame of reference, so this law is defined in practice this important concept of inertial frame of reference.

通常把牛顿第一定律成立的参照系成为惯性参照系，因此这一定律在实际上定义了惯性参照系这一重要概念。

Foucault's pendulum, and other much more sensitive experiments, demonstrate that an inertial frame is also one in which the distant galaxies do not appear to rotate.

一节，我们介绍了惯性系的概念：找一个参考系使牛顿定律适用于傅科摆和其他更敏感的实验，而我们发现在这个惯性系中遥远星系是不转动的。

Are these trends not comparable with Newton's law of inertia?

这些趋势难道和牛顿的惯性定律不是很相仿吗？

It means beating the Law of Inertia.

这意味着击败惯性定律。

We have seen that this law of inertia cannot be derived directly from experiment, but only by speculative thinking consistent with observation.

我们已经知道，这个惯性定律不能直接从实验得出，它只能根据思索和观察得出。

Well, the law of inertia says that something in motion will tend to stay in motion, and what's more, to move in a straight line.

惯性定律说，任何处于运动的物体会继续保持运动，而且，会在一条直线上运动。

Objects are compared with the rotational inertia, but it said with the first law of inertia is not the same thing, it's the size of the moment of inertia.

物体相对于转动也有惯性，但它跟第一定律所说的惯性不是一回事，它的大小为转动惯量。

Galileo's conclusion, the correct one, was formulated a generation later by Newton as the law of inertia.

伽利略这个正确的结论隔了一代以后由牛顿把它写成惯性定律。

These changes violate Newton's First Law, the Law of Inertia which implies that more energy is needed to change inertia (to overcome frictional forces and inertia) than to maintain inertia (to overcome only frictional forces).

这些变化违背了牛顿第一定律，也就是惯性定理――在不受外力或所受外力为零的状态下，物体总保持匀速运动或静止――也就是要改变物体的惯性需要额外的能量大于保持物体惯性的能量。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
