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.

What is the upward force on objects in a fluid?
bouyancy
The force of a fluid that pushes an object up is called?
bouyancy or upthrust
What force is pushing up?
Bouyancy... its what makes things float in water.
What force in fluids described by Archimedes'principle allows objects to float?
bouyancy
What describes the notion that an object floats if the buoyant force on the object is equal to the objects weight?
Bouyancy is defined as the force on a object submerged in a fluid equal to the difference in weight of the object and the fluid displaced. If the total weight of the object is the same as the same volume of the fluid, the bouyant force is zero, and the object will stay in the same place.
What does bouyancy mean?
bouyancy- force of weight of gas fluids.
What force makes a whale surface?
bouyancy
What is the upward force on objects in a fluid?
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?
sure
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.
