is the center of gravity always on the center?

Answer 1

Its the center of the overall mass. not the center of area/volume. If you had a large lower portion of an object, which has a slimmer, tall portion, (say at a ratio of mass 2:1) the center of gravity is going to be roughly 1/3rd of the way down from the "volumetric" center.

Answer 2

Assuming continuous density of an object then the
center of gravity is the center of mass. And since the mass is determined by the volume and density, given any one shape, it doesn't matter what the density is, it will have the same geometric center and therefore the same
center of gravity. So it's geometric center that's equivalent to center of gravity. But it's a lot easier to
determine the center of gravity than it is to compute the
geometric center by measurements. Just hang an object by 3 non-linear points, and where the vertical axis's
intersect is the center of gravity and therefore the geometric center.

Answer 3

No. It could be any where depending on the shape and density. For instance, the center of gravity of an isocelles-triangle shaped, with uniform density and thickness material is at the point 1/3 height and 1/2 the base of the triangle. If you take a rectangular iron plate with uniform thickness and density and some how weld to a similar copper plate and try to find the center of gravity of the joined metal, it will be some where in the iron plate away from where the two metals are welded.

Answer 4

The answer is a simple No. The reason because the center of gravity deals with where the weight is divided evenly throughout the object. If a man has a gigantic head, and small lower body his center of gravity would be on his neck. Although usually it is in the middle.

Answer 5

"Center" is a relative term. The center of gravity is at the point where a system finds balance, i.e. its relative center. For example, a see-saw has a center of gravity that is in the true center of the see-saw board when the opposing forces on each end of the see-saw are equal. When the opposing weights are unequal, the center of gravity is adjusted to a point where balance is achieved. Here, the center of gravity will no longer be the true center of the see-saw board.

Answer 6

In a uniform gravitational field, center of gravity is right at the center of mass of a body. Now as you know, center of mass of a body does not necessarily lie at the "center" of a body. It depends upon distribution of mass and density of mass in the body. Consequently, center of gravity is not always at the center. Only a uniform density and symmetrically shaped body has its center of gravity at the center.

Answer 7

The center of gravity need not always be at the center.It depends on the shape of the object. For example, in a cube, the centre of gravity is exactly in the center. While in a baseball bat, it lies somewhere towards the bulgy portion of the bat.

Answer 8

No.

Imagine a sphere with its northern hemisphere made of solid iron and the southern hemisphere made of some lighter material.

It should be obvios that the enter of gravity would be somewhere inside the heavier half, not in the center of the sphere.

Note: There is a precise mathematical formula for finding the center of gravity. (It involves a volume integral though)

Answer 9

No the canter of mass is what counts for instance why does only one side always show to earth. The mass is to one side . There are several ways to stabilize a spacecraft ,one is spin stabilized the other is gravity gradient ,u place a good size weight Maby batteries etc. on a boom and that weight off center will hold that side always toward the earth.

Answer 10

By no means, it is the center of mass and not the center of the object. You have to do CM calculations to figure out where the true Center of mass is located. It all has to do with the distribution of weight in the ojbect.
