differences between centroid and Center of Mass

Here are the differences between centroid and Center of Mass

Centroid

• The centroid of an object is a geometric property that represents the "center" of the shape in terms of balance and symmetry.
• It is a point within the object that has the property that if the object were suspended at the centroid, it would balance perfectly in all directions.
• The centroid is based solely on the shape and geometry of the object and does not consider the distribution of mass within the object.

Center of Mass

• The center of mass (COM) of an object takes into account both the shape and the distribution of mass within the object.
• It is the point at which the entire mass of the object can be considered to be concentrated, so that if a force is applied at the center of mass, the object will move as if all its mass were concentrated at that point.
• The center of mass accounts for irregular or non-uniform mass distributions within the object.

In many cases, for symmetrical objects with uniform density, the centroid and the center of mass coincide, making them effectively the same point. However, for more complex shapes or objects with non-uniform mass distributions, the centroid and center of mass can be different.
