惯性定律

Newton's laws, concepts of momentum, energy, angular momentum, rigid body motion, and non-inertial systems.

牛顿定律，动量的概念，能量，角动量，刚体运动，以及非惯性系。

The laws of mechanics are the same in all inertial frames of reference. This is called Galilean relativity

在所有的惯性参照系中，力学定律都是一样的，这叫做伽利略相对性。

Week 2 Newton three law and its application, non-inertial system, inertial force.

第2周 牛顿三定律及应用，非惯性系、惯性力。

In Inertial frames and why the laws are the same in the train and on the platform, we introduced the idea of inertial frames - a frame of reference in which Newton's laws work.

在"惯性系：为什么火车上和月台上物理定律是一样的？"

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。

According to the second law of Newtonian, inertial mass is a physical quantity represents the difficult degree for motion state to change when object stands a force.

根据牛顿第二定律，惯性质量是表征当物体受到外力作用的时候，物体运动状态改变的难易程度，即物体保持原来运动状态的本领大小的物理量。

The same laws of mechanics apply to all inertial systems moving relative to each other.

在所有作相对运动的惯性系中都可以应用同样的力学定律。

Hence, new physics would take into consideration at least one of three possibilities: clock acceleration, a modification of the law of gravity, or modified inertia.

因此，新的物理原理可能至少是这三种可能性之一：时钟加速，修改引力定律或者修改惯性。

In addition, there is a new cognition on inertial mass, Newton's second law, kinetic energy, mass-energy equation and momentum in the paper.

我们对惯性质量、牛顿第二定律、动能方程、质能方程、动量等重新进行了深刻地认识。

Explain this in terms of inertia and Newton's first law of motion.

请用所学的惯性和牛顿第一运动定律的知识作出解释。

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
