Does buoyancy force on a floating object depend on the weight of the object or the weight of the fluid displaced by the object?

If it's able to displace enough fluid for the weight of the displaced fluid
to equal its own weight, then it floats. This is the technology principle
utilized by boats and rubber duckies.

∙ 13y agoThe mass of a floating object is always equal to the mass of displaced fluid. In shipping, bouyancy is expressed as 'tonnage', which is how much weight can be placed in the vessel before it will submerge. The Titanic had a tonnage of 90,000 (=180 million lbs, = 82 million kilograms) in water. If the Titanic had an ocean of Mercury to sail in, you could put 1,224,000 tons on board because mercury is 13.6 times denser than water. So the 'force' is dictated by the density of the supporting fluid.

How do you determine the buoyancy of an object?
Any object wholly or partially submerged in a fluid experiences an upthrust equal in magnitude to the mass of the fluid displaced by that object. This is known as Archimedes' Principle. Archimedes also stated that for an object floating on a liquid, the weight of the displaced liquid is the weight of the object.
Why a ship which is made of heavy steel does not sink?
This is explained following Archimedes' principle; that is named after Archimedes of Syracuse who first discovered this law in 212 B.C.For more objects, floating and sunken, and generally in fluids; Archimedes' principle may be stated thus in terms of forces that; according to Archimedes; sates that "Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object".It is to be clarified that for a sunken object the volume of displaced fluid is the volume of the object, and for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.More specifically: Buoyancy = weight of displaced fluid.In simple terms, the principle states that the buoyancy force on an object is going to be equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g.Thus, among completely submerged objects with equal masses, objects with greater volume have greater buoyancy. This explains why the ship floats although made of heavy steel because it has bigger volume and accordingly is having higher buoyancy that keeps it floating.
What is the upward force that keeps an object floating on a liquid?
Buoyancy
Is buoyancy a balanced force?
Yes ... IF the object is floating. Otherwise no.
How does Archimedes principle relate the buoyant force acting on an object and the volume of the fluid displaced by the object?
The buoyancy force is equal to the WEIGHT of the volume of fluid displaced by the object.
What makes an object seem to weight less when you hold it in a pool of water?
This phenomenon is called buoyancy and is caused by the object displacing water equal to its volume. If the weight of the object is less than the weight of this displaced water, then the object has positive buoyancy and will float. If the weight of the object is exactly equal to the weight of this displaced water, then the object has neutral buoyancy and thus be weightless. If the weight of the object is greater than the weight of this displaced water, then the object has negative buoyancy and will sink but it still weighs less than it did out of the water.Just remember buoyancy only affects the weight of the object, it has no effect on the mass of the object which remains constant in or out of water.
Why is an immersed object buoyed up by a force equal to the weight of the fluid it displaces?
Because buoyancy is a property of fluids, and not the object immersed in them. By comparing densities, you get that buoyancy is equal to the weight of the fluid displaced, because the volume of an object is equal to the volume displaced.
What is when an object is placed in a fluid and the object weighs less by an amount equal to the weight of the displaced fluid?
"buoyancy"
How do you measure buoyancy?
place an object in a container with a fluid and find the amount of water it displaced. then find the mass of the object. then multiply the mass by the amount of displaced water♪
The water underneath the floating object exerts a push or force called?
buoyancy
What is the force exerted on an object is equal to the weight of the fluid displaced?
buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter
How does weight of an object immersed in a liquid affect the buoyant force on the object?
Not at all. (The buoyancy force equals the weight if the displaced water,)
