In general, an object's mass CANNOT change, unless you take something away from it or add something to it.
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.
The weight of the object would change if gravity changes. cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
Ok what is your query?
Yes, weight is directly proportional to the force of gravity acting on an object. If the force of gravity changes, the weight of the object will also change accordingly.
No, the mass of an object remains constant regardless of changes in gravity. Mass is an intrinsic property of an object and does not change with gravitational influence. The weight of an object, however, can change with variations in gravity, as weight depends on the gravitational force acting on the object.
No, an object's mass remains constant regardless of changes in gravity. Mass is an intrinsic property of an object and is not affected by the gravitational force acting on it. However, an object's weight, which is the force exerted by gravity on the object, will change with variations in gravitational pull.
Mass doesn't change. Mass the is substance of an object, moving it around won't affect how much mass it has, only adding or subtracting from the object would affect the quantity of mass. The weight would change because gravity is inversely proportional to distance but not the mass.
gravity
None
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
I suppose you are asking about what forces change when acceleration due to gravity changes. In this case, the formula for forces concerning acceleration due to gravity is as such: fg=mg. When acceleration due to gravity(g) changes, it affects the force of gravity which is also known as the weight of the object. This is shown as fg.
