| Abstract: | This paper discusses how the dynamic points and the dynamic reference system are selscted in composite movement and how the relative motion paths influence the computational points' absolute velocity and absolute acceleration.It proves that the relative motion paths have an effect only on the absolute acceleration of the points.It also expounds the principle of selecting the dynamic points and dynamic reference system. |
