Mass Center

The mass center, often called the center of mass, is the point where an object's entire mass can be considered to be concentrated. It’s the balance point, where if you supported the object there, it would stay balanced. Think of a seesaw: the center of mass is the spot where the seesaw balances perfectly when weights are evenly distributed. For irregular objects, the center of mass depends on how mass is spread out; shifting mass closer or farther from this point changes how the object balances and moves.
