A center of mass that, besides the center of gravity, is when the point of an object or system of material points in which the object's total mass is concentrated. This concept demonstrates that the item is one material point whose mass is equal to that body's total mass.
The center of mass occurs for any system of material points, whether a force is working on the body. With irregular geometric bodies, the center of gravity is at the intersection of the gravity lines. With centroid, which can also be called the geometric center, corresponds with the gravity center when it is homogeneous.
In physics, the body's centroid is illustrated as the focal point of the vector's collection of the acceleration of all material points of the same object. If the body is homogeneous, this point is positioned near the intersection of the gravitational lines. In right geometric bodies, it is determined geometrically, and this is called the center of gravity of an object.
