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.
The effect of gravity inside a solid sphere is that it pulls objects towards the center of the sphere, with the force of gravity decreasing as you move towards the surface. This is because the mass of the sphere is concentrated at the center, creating a gravitational pull towards that point.
No, the center of mass of a solid object does not necessarily have to lie within the object. For example, a hollow sphere or a ring has its center of mass located outside of its physical structure. This is because the distribution of mass in these objects is not uniform.
The center of mass of a solid object may or may not lie within the object. For example, in a uniform sphere, the center of mass lies within the object at the geometric center. However, in objects with irregular shapes or voids, the center of mass may lie outside the physical boundaries of the object.
The upward thrust which the surrounding fluid exerts on an object is referred to as the force of buoyancy. This thrust acts through the centroid of the displaced volume, referred to as the centre of buoyancy. The centre of buoyancy is not the same as the centre of gravity which relates to the distribution of weight within the object. If the object is a solid with a uniform density exactly the same as water and the body is immersed in water the force of buoyancy will be exactly equal to the weight and the centre of buoyancy will be the same as the centre of gravity. The object will be in equilibrium with the surrounding fluid.
Assuming a uniform gravitational field, center of mass and center of gravity are the same. The basic idea of center of gravity is it's the place where you apply a force to move it in a straight line without causing the body to rotate or move in other direction. So for a sphere, a cube, or any other symmetrical body, its at the geometric center, assuming the solid is of uniform density. See the Wikipedia link below for a more thorough treatment of the subject.
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.

The effect of gravity inside a solid sphere is that it pulls objects towards the center of the sphere, with the force of gravity decreasing as you move towards the surface. This is because the mass of the sphere is concentrated at the center, creating a gravitational pull towards that point.
That must be obtained through integration, meaning, you divide the solid into many small pieces.

The center of gravity of a triangle can be found by adjusting the thickness. You also need to find the density at the intersection.
2 apex fill-in-the-blank Q's: 1) The center of gravity of a trianglular solid with uniform thickness and density is at the intersection of the medians of the triangle. 2) The center of gravity of a triangular solid with uniform thickness and density is the centroid. medians the point at which one can balance the triangle. and the point shared by a triangle's medians. medians centroid Medians i got centriod?
Every speck of mass throughout any solid body "has gravity", and attracts every other speck of mass. But when you're outside of the solid body, the gravitational effect of all those specks of mass is exactly as if all of its mass were located at its "center of mass" or "center of gravity". For a homogeneous spherical object, that point is the center of the sphere.
the centroid the point at which one can balance the triangle
The heavier mass will be nearest to the center of mass. The concept behind this is related to the one that explains the center of gravity. The center of mass and the center of gravity are the same.
No, the center of mass of a solid object does not necessarily have to lie within the object. For example, a hollow sphere or a ring has its center of mass located outside of its physical structure. This is because the distribution of mass in these objects is not uniform.
