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.

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.
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.
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.
Explain how the buoyant force acting on an object placed in water can be measured?
The buoyant force acting on an object placed in water can be measured by finding the difference between the weight of the object in air and the apparent weight of the object when submerged in water. This difference is equal to the buoyant force acting on the object, which is also equivalent to the weight of the water displaced by the object. By measuring these weights, one can determine the buoyant force acting on the object.
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.

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.

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.
How can we measure the upthrust of an object?
The upthrust of an object can be measured by determining the difference between the object's weight in air and its weight when immersed in a fluid. This difference in weight is equal to the upthrust force acting on the object. It can be calculated using the formula: Upthrust = Weight in air - Weight in fluid.
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.
Why is there a difference between the weight of an object in the air and it's weight in water?
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
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.
What is the apparent mass in water?
The apparent mass in water refers to the apparent weight of an object when immersed in water. This weight is equal to the difference between the actual weight of the object in air and the buoyant force acting on it while submerged in water.
