What causes a decrease in an objects weight
Artist 52 [7]

The mass of an object can neither be change but the weight of the object can be changed.

<h3>What causes a decrease in an object weight?</h3>

The weight of the body or of an object can be changed if the body is placed farther away from the earth or placed in the planet which is far away from the earth's gravitational field, so  the force of gravity on the object will change. However the mass of the body or mass of the object will remains the same  regardless of whether the object is on Earth, in outer space, or on the Moon. By doing so the weight of the object or body will change but the mass remains the same.

So we can conclude that: The mass of an object can neither be change but the weight of the object can be changed.
