What's more likely: an object whose mass is 0, or an object whose weight is 0?

Answer 1

If an object's mass is exactly zero, then the object does not exist. No mass means no atoms. However, an object can have no weight and still have a mass. The weight depends on the gravitational force.

Answer 2

Every material object has mass. But its weight depends on the presence of other
masses to attract it gravitationally.

No material object can ever have zero mass OR zero weight. But since its weight
depends on the mass of other masses and its distance from them, you can move
the object around to different places and make its weight as small as you want it
to be.

Answer 3

i just found it out: No material object can ever have zero mass OR zero weight. But since its weight depends on the mass of other masses and its distance from them, you can move the object around to different places and make its weight as small as you want it to be.

Answer 4

An object with zero mass is more likely than an object with zero weight, since mass is an intrinsic property of matter, whereas weight is a force caused by gravity acting on an object's mass. A zero-weight object would require a lack of gravitational force, which is unlikely in most scenarios.
