Question

Difference between centroid and centre of gravity​

Answer 1

Centre of gravity is the point where the total weight of the body acts while centroid is the geometric centre of the object. Centre of gravity or centre of mass is the point where the whole mass of the body is concentrated. ... Centroid is the centre of gravity for objects of uniform density.

Answer 2

There are two major differences between "center of gravity" and "center of mass":
1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "centroid" applies to plan areas.
2) Center of gravity of a body is the point through which the resultant gravitational force (weight) of the body acts for any orientation of the body while centroid is the point in a plane area such that the moment of the area, about any axis, through that point is zero.
Center of gravity is the point at which a object can be suspended and be in perfect equilibrium
