Why does a heavy object fall at the same rate as a light object in a vacuum?
cause the two have lost their weight
Why do objects weigh more in vacuum than in air?
Weight is dependant upon gravity and the relationship to large bodies of mass such as planets. However, if you were to be put into a vacuum on the surface of the Earth, you would way less. There is air pressure pushing down on you and that would add some weight. It also pushes up on parts of you. The difference is not likely to be very significant, but it should be measurable. However, I don't volunteer to be the person in the vacuum chamber! I am not a scientist, but I believe that you would weigh very slightly more in a vacuum. Think of our atmosphere as being a liquid of very low density compared with water. An object that floats in water displaces water in the amount of the object's weight; if you put a scale under a floating object, the scale registers the object's weight as zero. A perfectly bouyant object has the same density (specific gravity) as water, and as such will have a substantial weight if measured on land. But it will have no weight if weighed in water. An object that sinks in water will have weight, but it will weigh its land weight minus the weight of water displaced by its volume. This should be the same for a person (in a pressure suit, of course). The person will not be bouyed up at all by the atmosphere.
What happens to the weight of an object when it moves farther away from the centre of the earth?
the weight of an object grows more
Given that a helium balloon weighs more in a vacuum chamber on earth than in the earth's atmosphere would a rock weigh more in a vacuum chamber on earth than in the earth's atmosphere?
Yes. Any material object in a fluid is "buoyed" up by a force equal to the weight of the fluid it displaces.In air, the weight of the rock is reduced by an amount equal to the weight of the air that would otherwise occupy the rock's volume if the rock were not there.
Do gravity affect the weight of an object?
Yes. Mass is constant for a given object. Weight is a function of mass and gravity, stronger gravity more weight.

Why object weight is maximum in vacu um?
Because there's no influence from buoyancy in vacuum.
How is an objects mass measured?
the amount of matter that an object contain the more mass an object has the greater its weight

What is volume weight and density?
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/volume)
Where can I buy a backpack vacuum from?
You can buy a backpack vacuum from Amazon they have several listed.
Do gravity affect the weight of an object?
Yes. Mass is constant for a given object. Weight is a function of mass and gravity, stronger gravity more weight.
What objects weight more than 500 grams?
The weight of an object is measured in Newtons and not grams, so there cannot be such an object. The question is like asking what object weights more than 500 metres!
What is the difference between friction and weight?
Friction is a force that stops almost every object so if there is more weight it is harder for the friction to stop the given object
How much more does an object weigh after it has been submerged out of water?
Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.
