| Abstract: | The centre of mass and centre-of-mass frame are introduced in the mechanics of Newton.But some authous introduce the centre-of-mass frame while others introduce the centre-of-momentum frame, in relativitic mechamics. The aim of this paper is to further comprehend their physi cal sense through cxplaining and comparing of these physi cal concept (idea)and to know their application in collision of high panicles. |

| Keywords: | centre-of mass frame centre-of-momentum frame relativistic particles system |
