Locating the Center of Mass
The position of COM is mass weighted average of the positions of particles. Mathematically, it is given as

Motion of the Center of Mass
We can describe the translational motion of a rigid body as if it is a point particle with the total mass located at the COM—center of mass.

Center of Mass of the Human Body
The center of mass (COM) is an important physical concept—it is the point about which objects rotate.

Center of Mass and Translational Motion
The COM (center of mass) of a system of particles is a geometric point that assumes all the mass and external force(s) during motion.
