| Abstract: | Two principles for choosing moving point and moving system are proposed when the motion is analysed with theory of complex motion. The common types of motion are analysed. A wrong idea that the relative motion between two particles related to the type of motion of moving system in the reference has been corrected. The effect of the relative path in the analysis of the motion is discussed. Finaly the relative path about eight kinds of mechanism are given with different methods for choosing moving point and moving system. |
