No. The classic counterexample is the torus (ring-shape); the center of gravity is in the geometric center of the ring, which is NOT part of the ring.

What will be the mass of a body at the centre of the earth as compared to other places on the earth?
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.
Where is the gravity center of human body on the earth?
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)
Does the center of gravity always lies on the body?
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
Is the center of gravity is always in the body?
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.
What would happen to your head if it was at the center of the earth?
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.
Is it necessary that centre of mass should always lie inside the body?
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.
Why is suns gravity only in the perimeter?
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.
How do we know whether a body is in stable or unstable state due to position of its centre of gravity?
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.
Where is the gravity center of human body on the earth?
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)
Is it necessary for the centre gravity to be situated inside the body of irregular shape?
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.
What does the center of gravity of a body mean?
Centre of gravity is the imaginary point where the total weight of a material body may be thought to be concentrated.
What will be the mass of a body at the centre of the earth as compared to other places on the earth?

How does a center of gravity affect the balance?
The center of gravity is the point where the weight of an object is concentrated. When the center of gravity is properly aligned over the base of support, it helps to maintain balance. If the center of gravity is outside the base of support, it can cause the object to tip over.
If the centre of mass of the body and the centre of gravity of machine will be at same point then is there any possible chance for vibration?
Yes there is.
What is center of gravity of a body?
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.
Give 5 to 6 Difference bw centroid and center of granvity?
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.
Can a body have two centers of gravity?
No, there is only one centre of gravity in which one's whole weight acts for any orientation of the object.
