What happens to the mass and weight when gravity changes?

Answer 1

If you say, double the distance, the force of gravity is one quarter

(f = 1/22 = 1/4)

If you say, treble the distance, the force of gravity is one ninth

(f = 1/32 = 1/9)

If you say, halve the distance, the force of gravity is four times

(f = 1/0.52 = 1/0.25 = 4)

Answer 2

In accordance to Newtonian gravitation, the acceleration of gravity is given by:

a=GM/r^2. This is a vector quantity, and thus can be decreased by other massive bodies. In addition to that, there is the fact that all objects do not have the same mass, and that the force is proportional to the inverse square of the distance to the center of mass. This means that depending on your distance to the center of mass, the value will be different.

Answer 3

The mass of an object does not change, regardless of gravity. If an object has 1 kilogram of mass, then it will have that much mass in space, where it weighs nothing, on Earth, or on Jupiter. Mass is a measure of the amount of "stuff", not the force of gravity upon that stuff.

Weight, on the other hand, measures the force of gravity pulling down on the mass. On Earth, our 1 kg object have about 9.8 Newtons of actual weight. In space, it has 0 Newtons, as it just floats away.

Answer 4

does anyone know, really need it for science classwork:)?

Answer 5

Force of gravity is not a constant. It will depend on the object mass, and distance between the 2 objects we are measuring. Refer to Newton's law of universal gravitation for more details.

Answer 6

The weight of the object changes, directly proportional to the sum of the mass of the object, and the increase in gravity. The mass itself remains unaltered.

Answer 7

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.
