its because the water puts fluid pressure everywhere on the object which creates a bouyant force.
fluid pressure
That force is bouyancy. Bouyancy is also present in a gas, but its effects are usually negligible except on objects with very low densities.
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.
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
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.
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.
Buoyant force is caused by differences in fluid pressure.Buoyancy is the upward force on an object produced by the surrounding fluid (could be a liquid or a gas) in which it is fully or partially immersed.
FALSE
FALSE
Because the buoyant force is the result of different pressure at different depths, and there is no difference in pressure horizontally.
by the teacher
The greater the pressure against the bottom of a submerged object produces an upward buoyant force
FALSE
greater than
true
greater than
The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.
It is called buoyant force. It is calculated by determining the volume of water displaced by the object, which is the volume of the object under water.The weight of this quantity of water is the buoyant force. It can also be calculated by knowing the depth of the object in the water, the pressure at that depth, and the area of the bottom of the object. Buoyant Force = Pressure * depth It can also be calculated by knowing the weight of the object. If an object is floating the water is supporting the object's weight. So the buoyant force = weight of object
