Buoyancy question: What does an object in water displace...?

The weight of water that the object itself weighs, or


The volume of water that is the same volume of the object?





Please, please help. I keep on getting confused with this.Buoyancy question: What does an object in water displace...?
An object immersed in water will displace the volume of water equal to the volume of the object itself.





When you combine this with weighing the object on scales, you can determine its density:


density = weight/volume





This does assume that the object is more dense than water, otherwise it will float. Metal ships float because, although the metal is more dense than water, it is filled with air - and the combined air+metal is less dense than water.Buoyancy question: What does an object in water displace...?
volume, the amount of space...
A ship displaces the volume of water that is taken up by the portion of the hull that is below water level. The weight of the ship detrmines exactly what that volume is.
If it is floating then it displaces its weight.





If it is submeged then it displaces its volume.
A floating object displaces its own weight of water.The reason it floats is that the displaceed water trieas to return to where it was and pushes back against the floating body with a force equal to its own weight A submerged object displaces its own volume. Think if this as a balance scale with the object on one side and the displaced water on the other side. The object will float when the weight of the displaced water just balances the object or is greater than the object
A body immersed in water is displaced by an amount of its own mass.
the volume of the object that is why dispacers with a known volume can be used to determine level in instrument and control devices such as in a water leg
