Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero.
Center of mass = [(mass of a point object)*(distance of that point from origin)]/(Total mass)
For a rigid body we need to integrate this expression.

Does the sun circle the earth or does the earth circle the sun?
They both rotate about the center of mass of the Earth Sun System. This center of mass is located inside of the sun but is not the exact center of the sun. As the sun revolves about this point inside itself this causes the sun to wobble slightly. This wobble is how we are able to locate extrasolar planets.
Where is center of mass of a sphere?
The center of mass of a sphere is its geometric center.
What is the relationship between center of mass and mass distribution?
Mass is uniformly distributed about its center of mass.
Where is the center of mass of a ball?
The center of mass of a soccer ball is its geometric center.
How can you locate the center of gravity?
Usually the centre of gravity is at the centre of the object, scaling from both sides OR centre of mass where the object is stable when holding it up on a pin point
How do you maintain center of mass when mass is added?
The simplest answer is to add the mass at the center of mass. In that case, the total mass will increase, but not the center of mass. If the additional mass is not added at the center of mass, then it must be balanced with more mass at a location on the object that depends upon the object's shape. That's where things get complicated.
What is the distance from the center of earth to its center of mass?
The geometric center and the center of mass of the Earth are essentially the same point.
What is the center of the mass of an object?
the center mass of an object is in the center of such objects. you can find it by spining the object. :)
What is the advantages of center of mass?
Center of mass has no advantages. It just kind of is.
What is the center of mass of an equilateral triangle?
Center of mass of an equilateral triangle is located at its geometric center (centroid).
What is the main difference between center of mass and center of gravity?
Since gravity is produced by mass, the center of mass is also the center of gravity. The only difference between these two concepts is that mass is a more basic quantity, so the center of mass would also be the center of inertia, as well as the center of gravity. In practice, these terms can be used interchangeably.
A uniform board 20.0cm x 10.0cm has mass of 200g masses of 50.0g 80.0g are attached at two corners at the ends of one of the longer sides locate the center of gravity?
