The position vector of the centre of mass rcm
Webb4 6.3 The Centre of Mass. The centre of mass (CM) is the point where the mass-weighted position vectors (moments) relative to the point sum to zero ; the CM is the mean location of a distribution of mass in space. I Take a system of n particles, each with mass mi located at positions ri, the position vector of the CM is defined by: Pn i=1 mi ... Webbis called the centre of mass of the given collection of the particles. If the position vector of the i th particle is 7-; , the centre of mass is defined to have the position vector 11 1 cm = M mi ri - Taking x, y, z components of this equation, we get the coordinates of centre of mass as defined above X = — 1 Em, xi, Y= —
