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.
What else can I help you with?
The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
Comparing the of an object with that of a liquid will tell you whether or not the object will float in that liquid?
density
Tendency of an object to float is called?
DensityThe lower the density in the liquid or air the more it will float
How does weight affect buoyancy?
It depends on the two materials involved. The underlying question here is what affect does temperature have on density -- because it is the relative density of an object that will determine whether it sinks or float in a liquid. Most often, the density of a material goes down with increasing temperature (in other words buoyancy goes up with temperature) -- but that is not always the case. Water is most dense at 4°C for instance, which is why ice cubes float. For any common material, it is trivial to find a graph of density versus temperature (try google.com for instance). The lower the density, the more buoyant it will be (it won't be buoyant at all in water if the density is above 1 gram/cm3 though).
Does volume affect whether an object will sink or float?
Yes, the volume of an object can affect whether it will sink or float. In general, an object with a greater volume will have greater buoyancy, making it more likely to float in a fluid. However, other factors such as density and the density of the fluid will also play a role in determining whether an object will sink or float.
What force determine whether or not an object will float?
i think buoyancy
How does the density of a liquid affect the density and buoyancy of an object?
The density of a liquid affects the buoyancy of an object by determining whether the object will float or sink in that liquid. If the density of an object is greater than the density of the liquid, the object will sink. If the density of the object is less than the density of the liquid, the object will float.
How The ability of an object to float on a fluid is influenced by the?
Buoyancy force is the upward force from the fluid acting on the object, based on the object's weight and the fluid's density. The object will float if its weight is less than the buoyancy force. The object's shape, density, and volume also affect its ability to float on a fluid.
What most influences whether or not an object will float?
The density of the object compared to the density of the fluid it's placed in is the primary factor influencing whether or not an object will float. If the object is less dense than the fluid, it will float; if it is denser, it will sink. Objects that are less dense than water, for example, will float in water.
What will affect an objects ability to float?
An object's ability to float mainly depends on its density. If an object is less dense than the fluid it is placed in, it will float. Other factors that can affect an object's ability to float include its shape, surface tension, and buoyancy force acting on it.
Does mass affect whether or not an object will float?
no and mass is air
What The tendency of an object to float is called?
buoyancy
How do fluids effect buoyancy?
Fluids affect buoyancy by exerting an upward force on objects placed in them, known as the buoyant force. The buoyant force is equal to the weight of the fluid displaced by the object, which helps determine whether an object will sink or float in the fluid. Objects that are less dense than the fluid will float, while objects that are more dense will sink.
Why do rocks sink and rubber balls float in a swimming pool?
Whether an object sinks or floats depends on the objects buyoncy. If an object has a higher buoyancy then water it will generally sink, and less it will float.
The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
How does the density affect bouyancy?
Density affects buoyancy by determining whether an object will sink or float in a fluid. An object with a density higher than the fluid it is immersed in will sink, while an object with lower density will float. This is because the buoyant force acting on an object is equal to the weight of the fluid displaced by the object, and density affects how much fluid is displaced.
