Buoyancy force or upthrust must be equal to the weight of the object for the object to stay afloat. If the weight is greater than the upthrust, the object would sink.

Is bouyancy a downward force exerted by a fluid on a body placed in the fluid?
No, buoyancy is an upward force exerted by a fluid on a body placed in the fluid. This force is equal to the weight of the fluid displaced by the body, according to Archimedes' principle.
What is an example of bouyancy?
An example of buoyancy is when a boat floats on water because the weight of the water displaced by the boat is equal to the weight of the boat itself. This principle is explained by Archimedes' principle, which states that the upward buoyant force on an object immersed in a fluid is equal to the weight of the fluid it displaces.
Who discovered bouyancy force?
Archimedes, a Greek mathematician and scientist, is credited with discovering the buoyant force while taking a bath. He realized that the upward force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.
What force in fluids described by Archimedes'principle allows objects to float?
bouyancy
What is the upward force on objects in a fluid?
The upward force on objects in a fluid is called buoyancy force. This force is equal to the weight of the fluid displaced by the object according to Archimedes' principle. It helps objects float or experience an apparent weight reduction when submerged in a fluid.
What does bouyancy mean?
bouyancy- force of weight of gas fluids.
What force makes a whale surface?
bouyancy
The force that makes a boat float?
The force that is at work is gravity. If you are thinking of bouyancy, it is not a force.

What is the bouyancy of air?
Bouyant force was described by Archimedes to be equal to the force due to gravity of the substance displaced by the object. So in the case of a balloon in water the bouyant force is equal to the force of weight of the water that the balloon displaces otherwise known as the (volume of the balloon)*(density of water)*gravity. Hope that helps
Why dosent a ship sink?
The bouyancy of the vessel keeps it afloat. As long as the force of bouyancy is larger then the mass of the ship it will stay afloat.

Is the reaction force always equal to the weight?
No, the reaction force is not always equal to the weight. The reaction force is the force exerted by a surface to support an object, while weight is a measure of the gravitational force acting on an object. In equilibrium, the reaction force is equal and opposite to the weight, but in other situations, such as when an object is accelerating, the two forces may not be equal.
How does buoyancy affect whether an object will sink or float?
If you just set the object in the water, the buoyant force never becomes greater than the object's weight. It sinks and sinks, displacing more and more water, building up more and more buoyant force, until the buoyant force is equal to its weight. At that point, the net force on it is zero, it stops sinking, and it stays right there (floating). The only way you can produce a buoyant force greater than its weight is to force it further down and hold it there. Since the buoyant force is greater than its weight, as soon as you let go, the net force on it is up, and it'll rise, partly out of the water until the buoyant force drops to equal its weight, and again ... it'll stay right there. So the answer to the question is: An object can't stay indefinitely in a position where the buoyant force is greater than its weight. If that happens, then it lifts some of itself out of the water, reducing the buoyant force, until the buoyant force is again just equal to its weight.
