What is the decrease in weight caused by the upward force of displaced fluid?

It is named after Archimedes of Syracuse, who first discovered this law. According to Archimedes' Principle, "any body fully or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced." When a body is fully immersed the weight of fluid displaced is equal to the volume of the body times the density of the fluid. So this amount will be the reduction in apparent weight of the body. If the body is floating, its apparent weight is reduced to zero, so the weight of fluid displaced must equal the weight of the body. In this case only part of the volume of the body needs to be immersed to displace its weight in fluid, because the body has a lower density than the fluid.

Why does bouyant force act upward on an object submerged in water?
Upthrust which is equal to weight of fluid displaced
What is the apparent mass in water?
Apparent Weight =weight Of Water- Upward Thrust =(mg- Density Of Water Displaced*volume Of Liquid*gravity)
Does the buoyant force on a submerged object depend on the weight of the object itself or on the weight of the fluid displaced by the object?
The upward bouyant force depends only on the weight of the displaced fluid. The NET force (object's weight - bouyant force) depends on the object's weight and will determine how fast it sinks.
The net upward force caused by displaced fluid is?
Its known as buoyancy, and is defined by the amount of water displaced. In general, it can be defined as: Force (lb or N)= 1/2*Unit Weight of Fluid*depth^2*length*width Unit Weight of Water ~ 62.4 lb/ft^3 " " ~ 9.81 kN/m^3 These values change depending on temperature
What is the upward force exerted by a fluid on a submerged object?
the weight water displaced (volume of the object times 62.4 for fresh water) minus the weight of the object in air
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
Why does bouyant force act upward on an object submerged in water?
Upthrust which is equal to weight of fluid displaced
What is the apparent mass in water?
Apparent Weight =weight Of Water- Upward Thrust =(mg- Density Of Water Displaced*volume Of Liquid*gravity)
Explain Archimedes' principle?
Archimedes' Principle relates the weight of a fluid displaced to the object placed in the fluid. If the weight of the fluid displaced is less than the object's weight ,then the object sinks. When the weights of the object and displaced water are equal, the object will float.

The upward bouyant force depends only on the weight of the displaced fluid. The NET force (object's weight - bouyant force) depends on the object's weight and will determine how fast it sinks.

Is gravitational force equal to the weight of the fluid displaced by an object?
No. Gravitational force is directed DOWNward. The weight of the displaced fluid is another force, directed UPward. If they happen to be equal, then the net force on the object is zero and it floats. But they don't have to be equal.
State Archimedes' principle?
Archimedes principles state dat wen a body is partially or completely immersed in a liquid the uptrust equal to the weight of the object displaced
What is the upward force exerted by a fluid on a submerged object?
the weight water displaced (volume of the object times 62.4 for fresh water) minus the weight of the object in air
Why does the human body feel lighter in water?
The downward force of gravity is counterbalanced by the upward buoyant force of the water, resulting in a net decrease of the body's weight. The buoyant force comes from the water that is displaced by the body (think of water rising in the tub when you get in). That displaced water tries to get back to its own (previous) level, so it pushes back on the body.
What is a force that helps a ship float?
The amount of water displaced by its base body is heavier than the weight of the ship.
Why do large cruise ships float in water?
This is because they displace a volume of water which has a weight equal to their weights. The upward upthrust is equal to their weights (upthrust = weight of fluid displaced)
