accelerates upward, and may shoot up out of the water.
If the buoyant force is equal to the force of gravity, then the object floats right there.

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.
How can you use the density of an object to predict whether it will float or sink in the water?
the buoyant force acts in the direction opposite to the force of gravity, so it makes the object feel lighter
How does the buoyant force affect a submerged object?
If the weight of the object is higher than the buoyant force the object SINKS. And the opposite happens if the weight is lower than the buoyant force. If it is equal, the object neither sink nor float, it is neutrally buoyant.
How is buoyant force and displacement related?
buoyant force is the result of the displacement of the fluid an object is in. if a fluid is displaced by the volume of an object, the weight of the fluid being displaced is pushing up on that object
What scientific rule states that the buoyant force an an object is equal to the weight of the fluid displaced by the object?
Since the object is submerged, we know that the buoyant force is not sufficient to overcome the weight of the object, otherwise it would be floating rather than being submerged. Therefore, the buoyant force is equal to the weight of the displaced water, not the weight of the object itself.
What are the rules of buoyancy?
If the force of gravity is greater than the buoyant force, the object will sink. If the buoyant force is greater than the force of gravity, the object will rise. If the force of gravity equals the buoyant force (neutral buoyancy), the object will float.
When the buoyant force is greater than the force of gravity an object will?
Float.
What is the relationship between buoyant force and gravity?
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.
What will an object do if the force of gravity is is stronger then buoyant force?
Sink
If two identical objects are placed in different fluids the buoyant force will be greater on the object in the?
The buoyant force will be greater on the object in the denser fluid.
What is the relationship of buoyant force to gravity?
the relationship between buoyant force and gravity is that both definitions have to do with floatation . gravity and buoyant both keep you your object afloat so that it does not submerge
Is the The greater the surface area of an object the greater the buoyant force.?
No.
When the buoyant force is equal to the force of gravity an object will?
float in the fluid
When the force of gravity is stronger than the buoyant force an object will?
fall
What happens to the buoyant force is greater than its weight?
If the buoyant force is greater than the weight of an object than the object will accelerate (assuming there are no other forces acting on the object)
What are the 2 forces involved in sinking and floating?
Gravity is pulling down, and Buoyancy is pushing up. When the force of gravity is greater than the buoyant force, objects sink. When the buoyant force is greater than the force of gravity, objects float.
When the buoyant force is stronger than the force of gravity an object will?
It will accelerate upward. When it reaches the surface and part of the object sticks out of the fluid, then the buoyant force decreases. When enough of it sticks out so that the buoyant force exactly equals the force of gravity (the object's weight), then it stops rising and stays right where it is (floats).
