What is the difference between centre of gravity,centroid and centre of mass ?

Centroid is the geometric centre of a plane figure or object

Centroid divides the shape into regions of equal moments.



Centre of mass is the mean location of all masses in a system


Centre of gravity is the point through which the weight of a body acts.


All these will coincide for a plane figure with uniform density and uniform distribution of mass
