does an object have weight when placed in a vacuum?

Answer 1

Yes. If the object is in free fall, it will accelerate indefinitely, because there is no air resistance.

Answer 2

Weight = Mass x Gravitational Acceleration

So as long as this object is still under the influence of a Gravitational Acceleration, it will have Weight, even if it is in a vacuum. The vacuum part will affect its motion, as there is no air resistance for example, so it is free to move and theoretically does not slow down.

Answer 3

All a vacuum means is that there is no air(i.e. no gas molecules). You can have a vacuum on earth. Everything in the universe has weight. It is just that you might way less in some places than others. But an object has a constant mass throughout the universe.

Answer 4

This question does not have limits set. When an object falls on Earth, the Earth causes a constant acceleration by gravity at the rate of 10 meters per second. As the object builds speed, collision with the atomsphere starts to provide more and more resistance. Eventually you will hit what is called terminal velocity. This is when you pick up no more acceleration. Now consider the vacuum condition. It is one of those "ideal" conditions where there is nothing that provide a resistance against acceleration. It is where the "falling" speed can increase to infinity pending the distance between the gravity source and the object falling to it. Also, the Speed of Light is only an average.

Answer 5

Weight is the pull of gravity relative to it's location. Create a vacuum around an object here on earth and it's weight will stay the same. Move the object to outerspace, and it's weight will be relatively non-existent due to it's distance from gravity inducing objects.

Mass will remain constant regardless of it's distance to any gravity inducing object.

Weight is the relative pull of gravity. Mass is a comparison to like objects (poor definition actually).

Answer 6

Vacuum is simply the absence of air and has nothing to do with gravity. An object's weight or mass does not change if the air around it is removed.

Answer 7

For the first guy... You are never able to have a perfect vacuum. If that were the case, objects that would be allowed to continue to gain speed in space (or a vacuum) would eventually reach light speed. This is of course not possible.

Answer 8

yes it would have because vacuum can be created even on earth as vacuum only means without air.i think that u wished to ask that does an object have weight when placed in space,so then it wouldnot have because gravitational force will not be there.but an object would have weight if placed on moon,mars because there is some gravity

Answer 9

The concept of weight is not tied to surrounding gases or the lack of them. Object has weight when some force is pulling it against a scale. This means that the answer can be both yes or no.

It has mass though. Mass in the sense of inertia.

Answer 10

Yes. You can observe that by looking at any clear lightbulb with a broken filament. It rolls around on the inside of the glass, not suspended in midair!

There is no friction from air in a vaccuum but you would need to escape the planet's gravitational pull
for the object to be weightless.
