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.

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.


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.


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.

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.
