Cornering at high speed
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.
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
No. Gravity always behaves according to the same formula, introduced by Newton.But the gravitational forces between you and the Earth certainly change when thedistance between you and the Earth's center changes significantly.
Drinking alcohol doesn't change a person's center of gravity but drinking too much can reduce a person's equilibrium.
No, because mass is the amount of matter contained in a body. So whatever may be the distance from the center of gravity it always remains the same.
A vehicle's center of gravity can change during different driving conditions based on factors like speed, acceleration, braking, and turning. For example, when a vehicle accelerates, the center of gravity shifts towards the rear, and when braking, it shifts towards the front. During sharp turns, the center of gravity shifts towards the side of the turn. These changes in the center of gravity can affect the stability and handling of the vehicle.
It depends on which reference frame you want to use. According to the reference frame connected to the crane, it will not change. According to the reference frame associated with the ground the center of gravity will of course change.
The center of mass and center of gravity serve two separate purposes. As an individual, your center of gravity and center of mass remains the same. The earth has a center of mass. The moon has a center of mass. The moon does not orbit the earth. They orbit their center of gravity. Their center if gravity is always changing. It is not a fixed point. When an airplane takes off, its center of gravity is one place. As it burns fuel, its center of gravity changes. It might be necessary to change its attitude, which today is done automatically by computers. The computers are checked at the end of the flight by human beings.
The location of an object's center of gravity depends on the object's shape, and on how its mass is distributed throughout its shape, but not on its size. The center of gravity of a homogeneous sphere is at the center of the sphere, no matter whether the sphere's radius is 1 millimeter or 1 light year.

No, acceleration due to gravity does not change the weight of an object. Weight is determined by the mass of the object and the acceleration due to gravity in that location. The acceleration due to gravity affects the force with which an object is pulled toward the center of the Earth, leading to its weight.
No. The black hole at the center of the galaxy is too far away to affect earth.
