WebThe center of mass of an object is a very particular point that physicists use to study the motion of an object or its equilibrium. Every object has a center of mass. If the shape of the object is weird, or if it is heterogeneous (made up of materials of different densities), then this point can be difficult to find, but it still exists.
WebFrom what I know, the centroid is the center of mass of an object. so, by definition its position is given by a simple mean of the positions of all the points in the object. For a polygon, it only has mass at the vertices. So, the centroid should be given by the arithmetic mean of the coordinates of the vertices. But Wikipedia says centroid is ...
