The ability of an object to float on a fluid is influenced by the object's buoyancy, which in turn depends upon at least three things: (1) the density of the object relative to the fluid; (2) the object's shape; and (3) the orientation of the object with respect to the surface of the fluid.
- An object that is less dense than the fluid (wood on water) will always float, regardless of its shape or orentation, and is thus always buoyant.
- An object that is more dense than the fluid (steel on water) will float only while the object's shape and orientation allow the object to displace more water than the object weighs. A steel boat floating upright on water is an example of a buoyant denser object.
- An object that is more dense than the fluid will sink if its shape and orientation do not make it buoyant, or if it is already fully immersed below the fluid line. A capsized steel boat will sink, for example, because its orientation with respect to the waterline no longer allows the boat to displace enough water to keep it buoyant.

The buoyant force on an object is least when the object is?
The buoyant force is zero when the object is just touching the liquid. As the object displaces more volume, the buoyant force increases until the object is completely submerged. Once the object is submerged, it doesn't matter how deep it is, the buoyant force remains constant.
When the buoyant force is equal to the force of gravity an object will?
When the buoyant force is equal to the force of gravity, the object will float at a constant position in a fluid. This is known as the principle of buoyancy, which states that the buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object.
In a vacuum does an object have buoyant force?
No, an object in a vacuum does not experience buoyant force because there is no surrounding fluid to displace or exert an upward force on the object. Buoyant force is a phenomenon that occurs in fluids, such as air or water, and is responsible for objects floating or sinking.
What does pressure do for floating and sinking?
Pressure plays a role in determining whether an object floats or sinks by affecting the buoyant force acting on the object. If the pressure on an object is greater than the buoyant force, the object will sink. Conversely, if the pressure is less than the buoyant force, the object will float.
An object with a mass of 4.6 kilograms and a volume of 0.0025 cubic meters is submerged in water. What is the buoyant force on the object?
The buoyant force is equal to the amount of water displaced. Multiply the volume of the object by the density of water - then convert that to a force (at about 9.8 newton/kilogram).
What is the buoyant force on a massless object?
The buoyant force on a massless object is equal to the weight of the fluid displaced by the object. This is because the buoyant force depends on the volume of fluid displaced, not the mass of the object.
Is The buoyant force on an object depends on the volume of the object that is underwater?
Yes, the buoyant force on an object is equal to the weight of the fluid displaced by the object. This depends on the volume of the object that is submerged in the fluid, as it determines the amount of fluid displaced.
True or false an object buoyant force and weight arent the same thing?
Yes they are different things. Buoyant force is always upward. Weight is always downward. Also ... -- Weight depends on the object's mass. -- Buoyant force depends on its volume, and on what it's floating in.
What is the buoyant force of a 150lb object submerged in water?
That completely depends on the object's volume (which you have not mentioned). The buoyant force on it is equal to the weight of an equal volume of water.
What is the buoyant force on a 240 newton object?
The bouyant force depends on the volume of an object. Specifically, the volume of fluid the object displaces.
Does the weight of an object immersed in a buoyant liquid affect the buoyant force on the object?
It is not the weight of the immersed object but the volume of the object would affect the buoyant force on the immersed object because the buoyant force is nothing but the weight of the displaced liquid whose volume is equal to that of the immersed object.
When an object floats the buoyant force is the weight of the object?
If the object is floating, then the buoyant force is equal to the object's weight.
Does the buoyant force on a floating object depend on the weight of the object itself or on the weight of the fluid displaced by the object?
The buoyant force on a floating object depends on the weight of the fluid displaced by the object, not on the weight of the object itself. This is known as Archimedes' principle.
What is buyoant force?
Buoyant force is the upward force exerted by a fluid on an object immersed in it. This force counteracts the weight of the object and depends on the density of the fluid and the volume of the object submerged. Objects that are less dense than the fluid will float due to the buoyant force.
How strong is buoyant force?
Buoyant force is a force exerted by a fluid that opposes the weight of an object immersed in the fluid. The strength of the buoyant force depends on the volume of the fluid displaced by the object. It can be calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced.
Does the buoyant force on a submerged object depend on the weight of the object itself or on the weight of the fluid displaced by the object?
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.
What property of an object determines the strength of the buoyant force acting on the object in a fluid?
The buoyant force acting on an object in a fluid is determined by the volume of the object displaced by the fluid. This volume is known as the displaced fluid volume, and it depends on the shape and size of the object in relation to the fluid.
