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.

Why does the weight of an object change in water?
because water weighs more than air, and there for, the weight difference between the water + object is less, making it seem as if the object has a smaller mass. Eg. Air = 0 (because we cant weigh it, so we set it as neutral) Water = 25 Object = 100 Object out of water = 100 Object in water = 75. Making it seem lighter
What is the difference between water weight and fat?
well its pretty simple, water weight is the water you drink and fat is yo mama!
Why does buoyant force vary with depth of the submerged object?
The buoyant force is equal to the weight of water displaced. For a dense object, such as a coin or a bowling ball, the weight of the object is greater than the buoyant force and the object will sink if you let go of it. For a less dense object, such as an ice cube or a block of balsa wood, the buoyant force is greater than the weight and you can feel it pushing the object toward the surface, resisting your attempt to hold it submerged. If you let go, the object will rise up and float.
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.
What is the origin of upthrust in fluid?
The difference in pressure between the top and bottom of the object.
What is water buoyancY?
The difference between an object's weight, and the weight of water with the same volume as the object.

What is the difference between the weight of 1 gallon of water and 1 gallon of paint?
no difference
What is the difference between fish and cats?
the difference is a cat has fur is a mammle and has legs a fish has scales fins and lives in water

Does water affect the weight of an object the same thing as does submerging something in water affect the weight of an object?
Yes, when the object is submerged in water then water exerts opposite buoyonci force which decrease the weight of object.
What happens when the water around objects have a force greater than the object's weight?
The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.

What is Archimedes princible?
Archimedes principle states that : The force of buoyancy is equal to the weight of the displaced water. If the weight of the water displaced is less than the weight of the object , the object will sink. Otherwise the object will float , with the weight of the water displace equal to the weight of the object.
How do calculate density for an irregularly shaped object?
You need to determine mass and volume and then divide the mass by the volume to get density. Refer to related link article for additional information on calculating density by water displacement.
