Thus the center of mass of the system is the point at which the total mass of the system could be concentrated without changing the moment.

Centre of mass formula list pdf. Center of mass The center of mass of a body or a system of bodies is a point that moves as though all the mass were concentrated there and all external forces were applied there. The centre of mass coinciding with the geometric centre for the circular shape. Similarly the center of mass is a point which locates the resultant.
