Difference between centroid and centre of gravity?

Question

Accepted Answer

Centroid and center of gravity are similar concepts, but differ in their applications and calculations.

Centroid is the geometric center of a shape, while center of gravity is the point where the total weight of an object is considered to act.
Centroid is used in statics and geometry, while center of gravity is used in physics and mechanics.
Centroid can be calculated using geometric properties, such as area or volume, while center of gravity depends on the distribution of mass.
For symmetrical objects, centroid and center of gravity coincide, but for irregular shapes or objects with varying density, they may differ.
Example: In a uniform rectangular plate, the centroid and center of gravity are at the same location, but in a T-shaped object, they may be different.

Accepted Answer

Centroid is point where whole area or volume can assumed to be act 
 Centre of gravity is that where whole mass can assumed to be act
