What is the difference between Centre of Mass and Centre of Gravity?

Question

Accepted Answer

Centre of Mass is the average position of mass in an object, while Centre of Gravity is the point where the entire weight of an object can be considered to act.

Centre of Mass is a geometric concept, while Centre of Gravity is a force-related concept.
Centre of Mass depends on the distribution of mass in an object, while Centre of Gravity depends on the distribution of weight.
Centre of Mass can be outside the physical boundaries of an object, while Centre of Gravity is always within the object.
Centre of Mass is used in physics and engineering calculations, while Centre of Gravity is used in mechanics and statics.
For a uniform object, the Centre of Mass and Centre of Gravity coincide.
In a non-uniform object, the Centre of Mass and Centre of Gravity may not coincide.
