what fact affect the weightof an objects?

Answer 1

To be a little more specific, weight is mass x acceleration. Gravity treated as an acceleration in physics, so, as mentioned before on the moon there is less mass than on the earth.
The difference is that weight of an object with a specific mass is different along different distances from the center of the earth. As well, rotation affects this acceleration, so that a given mass is less "weighty" at the equator than at the poles at a constant distance from the center of the earth.
Weight is also greater at sea level than at the top of a mountain. Minor issues, but wieght is mass x acceleration.
Change mass as discussed before, or change acceleration. Gravity is only one kind of acceleration.

Answer 2

Density and volume are the determining factors in the weight (mass) of an object. The formula is
MASS = DENSITY x VOLUME

As density or volume is increased the mass goes up. Weight is really more the "felt" mass of an object. The same amount of gold would weigh less on the moon due to lower gravity.

If you were to bombard a metal with radiation you can change the atomic structure of the object and change the density.

The weight of an individual object should be constant. There are exceptions. If that object is living, weight gain/loss is continuous, as the creature eats or even breathes. If the object is made of a reactive compound, like iron, it can oxidize when exposed to air. The oxidation (rust) will increase the weight of the object.

Answer 3

Dude it mass that occupies an empty space

Answer 4

density, volume, and gravity

Answer 5

helllloooo!!!!!! is this a part of psychology?
