No, but the difference between the buoyant force and the weight of the object will determine whether it floats or sinks.
The upward bouyant force depends only on the weight of the displaced fluid. The NET force (object's weight - bouyant force) depends on the object's weight and will determine how fast it sinks.
The buoyant force on a submerged object depends on the volume of the object. It is equal to the weight of the fluid displaced by the object, which is determined by its volume. The weight of the object itself affects the net force experienced by the object when submerged.
The buoyant force on any object in a fluid ... whether partially or fully submerged ... isequal to the weight of the fluid displaced by the object. That's related to the object'svolume, and has nothing to do with its weight.
The buoyant force acts upward on an object submerged in water because of the difference in pressure between the top and bottom of the object. The pressure at the bottom of the object is higher than at the top, resulting in a net upward force on the object. This force is equal to the weight of the water displaced by the object, pushing it upward.
The bouyant force on an object is equal to the weight of the fluid the object displaces.
If you want to test the principle that the bouyant force on a submerged object is equal to the weight of the water it displaces, here is a procedure. Get a balance scale and weigh the object by hanging the object from a string attached to the scale pan (rather then just placing it on the pan). Next, place the hanging object in a graduated cylinder with a known amount of water. The water level in the graduated cylinder will rise when the object is submerged. The amount the water rises will give you the volume of water displaced and you can calculate the weight of that amount of water knowing the density of water. Next, readjust your balance scale to get the object's weight while submerged. You should find the objects weight has decreased by an amount equal to the weight of the displaced water. Meaning the water is exerting an upward "bouyant" force by this amount.
It sinks
It reduces the object's apparent weight,sometimes to zero and even beyond.
The buoyant force on an object depends only on the weight of the fluid displaced: Fb = Vd*ρf*g Vd may not be the volume of the object; for example: if the object is floating on the liquid surface. Also, there may be other forces acting on the object, such as its weight (Mo*g)
Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.
Buoyant force is the upward force exerted by a fluid (such as water or air) on an object submerged in it. It is equal to the weight of the fluid displaced by the object and acts in the opposite direction to gravity, helping objects float.
The buoyant force on any object in water is equal to the weight of the displaced water, regardless of how much of the object is submerged.
