| 摘 要： | 介绍了相对论中的加速度和作用力的定义式及相应的洛仑兹变换式，探讨了相对论的加速度与作用力的特点，并与经典力学作了简单比较。讨论了加速度与作用力、速度这３个矢量之间的方向关系，并给出了相应的数学表达式，由此得到结论：当ｖ与Ｆ的夹角为锐角时，Ｆ位于ａ与ｖ之间；当ｖ与Ｆ的夹角为钝角时，ａ位于Ｆ与ｖ之间。

| Abstract: | The acceleration and force in special relativity and their Lorentz transformations are introduced. The natures of acceleration and force in special relativity are explored and compared with the correspondings in Newtonian mechamics. The orientation relations among three vectors of acceleration, force, velocity are discussed and their expressions are given respectively. The conclusion is that lies between and if the angle between and is acute; and lies between and if the angle between and is obtues. |
