通过对周衍柏编写的《理论力学教程》第二版中的弧坐标中质点加速度表达式的推导作些改进。

In the book Course of Theorical Mechanics by Yanbai Zhou there are some mistakes about the expression of acceleration in arc coordinates, this paper has corrected them.

本文提出质点和质点系(绝对运动和相对运动)质量加速度矩定理。

This paper proposes the theorem of moment about mass acceleration of the particle and the system of particles (absolute motion and relative motion).

在伽例略变换下，巧妙利用零矢量，给出了任意正交曲线坐标系中质点速度和加速度的矩阵表式方法。

Under Galilean transformations, expressions of Veloeities and accelerations in vertical curve Coordinates are derived by the ingenious use of Zero Vector and means of matrix.

The answer is that simply knowing the particle has an acceleration is not enough to tell you where the particle will be.

答案是这样的,仅仅知道质点的加速度,是不足以告诉你它接下来的运动的

This particle is constantly changing its direction, but it therefore has an acceleration and the acceleration, we have shown here, is pointing towards the center.

这个质点恒定地改变它的运动方向,因此它具有加速度,而且这个加速度,我们前面也讲过了,指向圆心
