Is the center of gravity of a glass tumbler closer to its bottom or mouth?

It's slightly closer to the bottom when the tumbler is empty, and moves higher
as the tumbler is filled, winding up near the middle when it's completely full.

Do the center of the gravity always coincide with the geometrical center of the object?
Only if the object is homogeneous, i.e. the mass is uniformly distributed. If the object is lumpy, or has thick spots and thin spots, then the center of gravity isn't related to the geometric shape. Consider a see-saw with a light kid on one end and a heavy kid on the other end. The geometric center is the mid-point of the board, but the center of gravity is closer to the heavy kid.
Explain why air has pressure?
The simplest explanation is that air is composed of gases. Gases are composed of molecules. Molecules have mass. The closer molecules get to the center and bottom of the gravity well, the more closely packed they become, because successive "layers" pack down on those below, piling up. The weight of the gases on top of those on the bottom compress those on the bottom.
What are two ways you can increase gravity?
You cannot increase gravity, but you can increase the force of gravity on a piece of matter with mass by1. Making the piece of matter larger2. Making it more dense3. Moving it closer to the center of a separate piece of matter.
Can you jump higher on a mountain then at sea level?
Yes, but not with any noticeable difference. The reason behind this is that gravity pulls the center of each object together. The farther away the centers are, the less effect gravity has on the objects. The closer the centers are, the greater the gravity.
Why does the force of gravity do work on a car that rolls down a hill but no work when it rolls along a level part of the road?
on earth... as you get closer to the earths core the gravity becomes stronger.. therefore the bottom of the hill being closer to the core the gravity is stronger then the more distant top of the hill. as for the smooth road the gravity is pulling equally on all sides of the car so it cancels its self out and results in u not moving
What happens as you get closer to the center of the earth?
As we get closer to the center of the earth, the gravity of earth increases and the heat too increases...thats what i think.
Why is gravity stronger at the poles than the equator?
The closer an object gets to the center of the earth, the greater the pull of gravity on that object.
Why is gravity stronger at the poles?
You are closer to the center of the earth at the poles, r is smaller in g=GM/r2
Where is the giraffes center of gravity?
The centre of gravity for a giraffe is almost in the middle of it's stomach but closer to the front. That is why the giraffe can slide down and not tip over.
Why are the most dense materials the bottom layer in the earth?
Gravity !... Gravity draws everything towards the centre of the Earth - therefore the heaviest materials are closer to the core.
Why is gravity slightly weaker on the continents than over the oceans?
The Continents are further from the center of the earth, leaving the oceans to be closer which means gravity is slightly weaker
Is gravity higher in one part of the earth than another?
Yes, gravity is slightly stronger closer to the center of mass of the earth. So at the top of a mountain the effects of gravity are less than at sea level.

Where is the force of gravity maximum?
The greater the product of two masses, and the closer together they are, the greater the force of gravity is between them. There's no limit. On earth, the greatest force of gravity on any object occurs when the object's center of mass is closest to the ground.
