Mass is conserved which means that a body will have the same mass wherever it goes. But at the centre of a masive sphere the body has no gravity acting on it so its weight is zero. At an intermediated radius the force on it is obviously less than at the surface, and Isac Newton proved that a body at a given distance inside a sphere feels a gravitational force from a sub-sphere of radius equal the distance of the body from the centre. In other words the body feels no gravity from the shell outside its own radius.
If you want to define total centre of gravity of a person, you must know:the mass of each body segmentsthe x, y and z coordinate of centre of gravity of each body segment (3D motion)
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
No, the center of gravity of an object is not always located within the physical boundaries of the object. It depends on the distribution of mass in the object. The center of gravity is the point where the entire weight of the object can be considered to act, and it can be located both inside and outside the physical boundaries of the object.
It, and everything inside it, would be crushed (this is, of course, if the centre of the Earth was empty, because if it wasn't, then you would be burnt to a crisp due to the immense heat fo the centre of the Earth). Your head would be crushed because gravity pulls you to the centre of the Earth, and if this is happening all over the Earth, then loads of gravity is going into one spot in the centre of the Earth. This would all push at you on all sides and subsequently crush you.
No, it may lie outside the body. In case of a circular ring, it is at the centre of the ring which is outside the mass of the ring.
It isn't. Gravity can be viewed as emanating from the centre of a body with mass. As the distance increases from the centre then the gravity decreases.
If the center of gravity of a body is located directly above its base of support, the body is in a stable equilibrium. If the center of gravity is located outside the base of support, the body is in an unstable equilibrium and more likely to tip over. The stability of a body is determined by the relationship between the center of gravity and the base of support.
No, the center of gravity of an irregularly shaped object does not have to be located inside the object. The center of gravity is the point where the weight of the object is concentrated, and it can be located both inside and outside the object depending on its shape and distribution of mass.
Centre of gravity is the imaginary point where the total weight of a material body may be thought to be concentrated.

Yes there is.
The center of gravity of a body is the point where the entire weight of the body can be considered to act. It is the point about which the body will remain balanced in any orientation without any rotation. It is determined by the distribution of mass within the body.

1.centeroid is the centre where all the mass of the body exist while centre of gravity is the place where the whole mass of the body exist. 2.centeroid is composed of different words while centre of gravity consists of others.
No, there is only one centre of gravity in which one's whole weight acts for any orientation of the object.
No, the center of gravity of a solid body may not always lie within the body. It depends on the distribution of mass within the body. If the mass is distributed symmetrically, then the center of gravity will be located within the body. However, if the mass distribution is asymmetrical, the center of gravity may lie outside of the body.
