The center of gravity is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed. If a body is of uniform density and has a symmetrical shape the center of gravity is in the geometric center. If the object is not symmetrical and does not have uniform density, it is more difficult to describe the location of its center of gravity.
the centre of the earth is the centre of gravity of a body.
A body will have a single center of gravity.
The center of gravity of a solid body does not always lie within the body. An example of this is a hula hoop. The center of gravity does not lie on the hoop that rotates.
That "point" in a body where the entire weight of the body can be represented to be present. Extend your knowledge by exploring where the center of gravity would be for metal shapes formed in the shapes of circular, square, rectanglar, hexagonal rings with metal rods. Where would the center of gravity be, on the ring or outside the ring?

For a uniform symmetric body in all directions the center of mass and center of gravity are the same point. Comment: I would say this happens when the force of gravity is the same at all points on a body. That means there are no variations in the gravitational field.

If the gravity is not constant over 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.
yes ,when centre of gravity and center of mass is at a st.line the body is balanced.

Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide

it is the field that atract our body toward it by hight and wightANS2:The center of gravity is synonymous with the center of mass and it is located near the geometric center of the planet.

In ballet, he center of gravity should always be in the middle of your body, no matter what you are doing.
