Objects do not actually weigh more in a vacuum compared to in air. Weight is the force exerted on an object due to gravity, and this force remains constant regardless of the medium the object is in. However, objects may appear to weigh more in a vacuum because there is no buoyant force acting on them, which is present in air and can partially counteract the force of gravity. This lack of buoyant force in a vacuum can make objects seem heavier when compared to their weight in air.
Well, sweetheart, objects don't actually weigh more in a vacuum than in air. Weight is the force of gravity acting on an object, and that force remains the same regardless of the medium. However, objects may feel heavier in a vacuum because there is no buoyant force from air pushing up against them, making them seem more substantial.
Oh, dude, objects don't actually weigh more in a vacuum than in air. Weight is determined by the gravitational pull on an object, which remains the same whether it's in a vacuum or surrounded by air. So, like, don't worry, your scale won't start lying to you just because you're in space.
Objects weigh the same in a vacuum as they do in air. Weight is a measure of the force of gravity acting on an object, and this force is not affected by the presence or absence of air. However, the apparent weight of an object may seem different in a vacuum due to the lack of buoyant force from the 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.
An object will weigh more in vacuum than in air because of the upthrust. There is no upthrust in vacuum whereas in air the pressure pushes an object or person from all sides. The air is dense and it is similar like water where the weight of an object is equal to the weight of the water displaced by it.
There is a buoyant force in water that largely counteracts gravity. Since the human body is about the same density as water, buoyancy just about completely cancels out the force you feel from gravity, effectively rendering you almost weightless. Since air is so much less dense than water the buoyant force you experience is negligible.
This is because there is no upthrust in vacuum so the gravitational force is the weight. In water, there is an upthrust which gets subtracted from the gravitational force. Therefore a body always weighs more in vacuum than in air.

Why do objects with more mass weigh more than objects with less mass?
Objects with more mass weigh more because weight is directly proportional to mass. The gravitational force acting on an object is stronger when the object has more mass, resulting in a greater weight measurement.
Is 1kg of lead in vacuum heavier than 1kg of feather in vacuum?
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.
Why do objects that weigh less exert more downwards force than objects that weigh more?
Objects that weigh less exert less downward force due to gravity compared to objects that weigh more. Gravity acts on all objects equally, causing them to fall at the same rate regardless of weight. However, weight is a measure of the force of gravity acting on an object's mass, so objects with more mass will have a greater weight and exert a greater force on a surface when supported.
What are three objects that weigh less than a kilogram?
A feather, a smartphone, and a pencil each weigh less than a kilogram.
Do objects weigh more in the air or in water?
Objects weigh less in water than in the air because water exerts an upward buoyant force on the object, partially offsetting its weight. This is known as buoyancy, which makes objects feel lighter in water than in air.
Why do objects weigh more in water than land?
they don't
How can you show that objects weigh more on earth than on the moon?
ask einstein
Why do objects with more mass weigh more than objects with less mass?
Objects with more mass weigh more because weight is directly proportional to mass. The gravitational force acting on an object is stronger when the object has more mass, resulting in a greater weight measurement.
How much does 1 million weigh?
One million is a number, and as such, it is a concept rather than a physical object, and has no weight. You could weigh a million objects but you would have to say which objects they are; a million elephants weigh more than a million apples.
Is 1kg of lead in vacuum heavier than 1kg of feather in vacuum?
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.

Will a body weigh more in air in vacuum when weighed with a spring balance.give a reason for your answer?
The body would wiegh more in air than in vaccum because as we know that there many particles in the air and so their weight whether less or more will be considered with it but in vaccum it's opposite.
What are three objects that weigh less than a kilogram?
A feather, a smartphone, and a pencil each weigh less than a kilogram.
Can you give me five objects that weigh more than 5 kg?
Sure, here are five objects that typically weigh more than 5 kg: a bowling ball, a standard car tire, a medium-sized watermelon, a gallon of milk, and a small dumbbell.
Do objects weigh more in the air or in water?
Objects weigh less in water than in the air because water exerts an upward buoyant force on the object, partially offsetting its weight. This is known as buoyancy, which makes objects feel lighter in water than in air.
Are objects in vacuum heavier than air?
No, objects have the same weight in a vacuum as they do in air. Weight is a measure of the force of gravity acting on an object, which is independent of the surrounding air or lack thereof. However, objects feel lighter in a vacuum because there is no air resistance to oppose their motion.
What are four objects that weigh less than a kilogram?
A feather, a smartphone, a notebook, and a pencil each weigh less than a kilogram.
