The position vector of the centre of mass rcm
WebbThe vector addition of the weighted position vectors indicates the centre of mass of every single object of the system. Along every single axis, the calculation for the centre of mass is individually done for the components. Centre of Mass of a two particle system is rcm = (m1 r1+ m2r2)/ ( m1 + m2 ). Centre of Mass of a Two-Particle System
