To remove the ambiguity, these laws should refer to the velocity and the acceleration of the center of mass . 要避免含糊，这些定律所指的应当是质心的速度和加速度。
Statics treats of special cases in which the acceleration is zero, and kinematics deals with motion only . 静力学是研究加速度为零的特殊情况，而运动学只讨论物体的运动。
Hence the equations of motion with constant acceleration can not be used to find the speed at other point of the path . 因此，不能用匀加速运动方程来计算路径上其他点的速率。
Nothing was said in the preceding discussion regarding the units in which force, mass, and acceleration are to be expressed . 在前面的讨论中，没有提到力、质量和加速度的单位。
It is clearly to be seen, how the thermoshock increases considerably with a decreasing duration of acceleration . 可以很清楚地看到，随着加速时间的减少，热冲击是增加得何等之快。
But to simplify that analysis we shall regard the acceleration as constant, our estimate will not be affected . 但为简化分析起见，我们称这种加速为常量，这样做不会影响我们的讨论。
This result confirms that the electrons deliver to the target the kinetic energy acquired during their acceleration . 这个结果证实了电子把它们在加速期间所获得的动能全都传递给了靶子。
In the absence of ground acceleration data, the nature of the input excitation can be inferred only from structural behavior . 在没有地面加速度数据的情况下，只能从结构的性状来推测输入激振的性质。
On the newtonian theory, for instance, acceleration varies with distance, but distance also varies with acceleration . 例如根据牛顿的理论，加速度随着距离的不同而变化，但距离也随着加速度之不同而变化。
Even for the most recent destructive earthquakes in the world there has been a lamentable lack of measured ground acceleration data . 即使不久前世界上发生的大地震，也十分遗憾地没有测到地面加速度数据。
