It means more or less the same as "center of mass" (there is a slight technical difference, which is not relevant for most cases). That would be a kind of "average position" of an object (technical note: this is a "weighted average", weighted by mass, and distance). If an object is hung up by its center of gravity, it would be perfectly balanced.
Yes, the position of the Metacentre depends on the position of the centre of gravity. If the centre of gravity is above the Metacentre, the ship will be stable. If the centre of gravity is below the Metacentre, the ship will be unstable.
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
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.
m/s2 means metres per second squared and it means gravity is the accelation of a body towards the centre of the earth.
gravity is a force by which objects are attracted to the centre of.
The way a plant grows or bends due to gravity is called geotropism.
Assuming the ball is a perfect sphere of uniform density, and is suspended from a massless string, the centre of gravity is in the centre of the ball.
The Earth's Core lies at the centre.
How do you find centre of gravity of a vehicle?
Lower the centre of gravity by adding weight at the base of the tower. Increase the width of the base to spread out the weight and lower the center of gravity. Ensure the center of gravity is directly above the base by adjusting the distribution of weight within the tower.
At the centre of the Earth.
Towards the moon's centre.
