An object's weight in air differs from its weight in water due to the buoyant force exerted by the fluid. When submerged in water, the buoyant force acts upward against the weight of the object, effectively reducing its apparent weight. This phenomenon is described by Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object. Consequently, while the object's mass remains constant, its weight appears less in water than in air.

What is the relationship between buoyant force and weight in air when submerged in water?
There's no relationship between the weight of an object in air and the buoyantforce on it when it's in water.The buoyant force is equal to the weight of the water the object displaces,which depends directly on its volume.Two objects that have identical weight in air will experience radically differentbuoyant forces in water if their volumes are different.
Why the weight of object in water is less than in air?
The force of Buoyancy in water subtracts from the weight of the object in air.
Where is the weight of an object maximum in air or Water or Vacuum or oil?
The weight of an object is maximum in air, as air offers more resistance to the weight of the object compared to water, vacuum, or oil.
How do you calculate the weight of an object under water?
To calculate the weight of an object under water, you can use the equation: Weight (in water) = Weight (in air) - Buoyant force. The buoyant force is equal to the weight of the water displaced by the object. By subtracting the buoyant force from the weight in air, you can find the weight of the object in water.
What is the difference of an object weight in air and in water?
The difference in an object's weight in air and in water is due to the buoyant force acting on the object in water. In water, the object displaces an amount of water equal to its volume, resulting in an upward buoyant force that partially counteracts the object's weight. This buoyant force reduces the object's effective weight in water compared to in air.
How do you calculate the buoyant force when given the air weight of an object's weight when submerged?
To calculate the buoyant force acting on an object submerged in water, you can use the formula: Buoyant force = Weight of the water displaced = Weight of the object in air - Weight of the object in water. This formula considers that the buoyant force is equal to the weight of the water displaced by the object.
Why is there a difference between the weight of an object in air and its weight in water?
weight of object in water = (Mass of object) time acceleration of gravity - Mass of an equal volume of water times acceleration of gravity. note weight of object in water can be a negative value.
Object Weights more in air water vacuum or hydrogen?
An object weighs less in air compared to its weight in vacuum or hydrogen, as air exerts a buoyant force on the object. The object weighs more in water than in air due to water's buoyant force. In a vacuum or hydrogen, where there is no buoyant force, the object's weight would be the same as its actual weight.
What force causes a difference in weight in air and water?
The force of buoyancy is responsible for the difference in weight between an object in air and water. In water, the upward force of buoyancy counteracts some of the object's weight, making it feel lighter. This is due to the water pushing against the object with an upward force equal to the weight of the water displaced by the object.
If an object weight 500g in air and 400g in water. what is the upthrust on it?
We can't find the term "upthrust" in any of the myriad volumes in our vast reference library. If the object's weight balances the weight of a 500g standard while in air, and the weight of a 400g standard while in water, then the effect of the water is to produce an upward force on the object equal to the weight of a 100g standard, or 0.978 Newton. By Archimedes' principle, this is also the weight of the water displaced by the object, which tells us that the object has a volume very near 100 cc.
What Air pressure exerted equally on an object from different directions is what type of pressure?
Air pressure exerted equally on an object from different directions is called hydrostatic pressure. This type of pressure is exerted by fluids, such as water or air, due to the weight of the fluid pressing down on an object.
Why the weight of an object is less in water than in air?
When an object is submerged it experiences a upward force called buoyancy. The buoyancy force is equal to the weight of the water the object displaces. So, if a 10-pound object displaces an amount of water that weighs two pounds (about a quart's worth), the apparent weight of the object under water is eight pounds.
