The discussion has served to emphasize the important role the inertia tensor plays in the discussion of the motion of rigid bodies . 讨论强调了惯性张量在论述刚体运动时所起的重要作用。
The assertion that the forms of the laws of physics are the same in all inertial systems is known as the principle of relativity . 在一切惯性系中物理定律的形式都一样，这样的结论称为相对性原理。
The outputs of these accelerometers are the three coordinates of the inertial velocity of the vehicle with the exception of gravity effects . 这些加速度计的输出是三个没有重力影响的飞行器惯性速度座标。
It is a remarkable fact that the inertial mass of all bodies is, within experimental accuracy, proportional to the gravitational mass . 值得注意的是，在实验的准确度内，所有的物体的惯性质量与引力质量都成正比。
Inertial guidance is often used in medium and long range missiles (over 40km say) when the intention is to hit a given map reference . 中远程导弹（比如说超过40公里）要想命中某一个给定的目标，经常采用惯性制导。
The use of inertia dyadics enables one to deal with certain topics involving inertia vector and inertia scalars in a basis-independent way . 在处理包含惯性矢量和惯性标量的某些问题时，应用惯性张量则可作到与基无关。
Inertial mass can be defined only in terms of certain mechanical measurements whose success hinges on newton's law of motion . 只有用某些力学上测量，才能给惯性质量作出定义，而这些力学上的测量的成就是随牛顿运动定律而定的。
Because of their inertia, the electrons will overshoot and oscillate around their equilibrium positions with a characteristic frequency known as the plasma frequency . 因为电子的惯性，它们将冲过平衡位置，并以特征频率围绕它们的平衡位置振荡。
Fundamentally an inertial navigation system is a dead-reckoning system with a very significant characteristic which differentiates it from more conventional dead-reckoning equipment . 原则上惯性导航系统是一种航行推算系统，与一般的航行推算装置不同，它具有极明显的特点。
