The force of gravity attracts objects to the centre of the earth. It does not let objects fly out of its pull.
Centre of gravity.
That would be at the point where the diagonals of the figure intersect.
No. As a simple example consider a donut shape! The center of gravity lies in the middle where the hole is.
Because gravity always tried to pull objects towards the centre of the earth !
gravity is a force by which objects are attracted to the centre of.
Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?

All objects which have mass have a centre of gravity.

The reason is gravity which, on earth, pulls all objects towards the centre of the earth.
The Moon has gravity, just like any other object, due to its mass.
Gravity accelerates the centres of the two masses towards their joint centre of mass. Obviously, if there is a huge difference between the two objects, such as a ball and the earth, the centre of mass of the combined system will be indistinguishably close to the centre of the earth and so it will accelerate the ball towards the centre of the earth. Also, while it will accelerate the earth towards the ball, the force will be too small to measure.
Because - the bottom of the hook will always be at the same position for objects of the same mass. Different sized objects may have the same mass - BUT - could have different centres of gravity.
