Does the mass of an object affect buoyancy force?
Weight is a measure of the force of gravity pulling down on an object, whereas buoyant force pushes up on an object. Which force is greater determines whether an object sinks or floats. Density, or the amount of mass in a given volume, is also related to the ability of an object to float.
Is buoyant force the same for all objects?
Examination of the nature of buoyancy shows that the buoyant force on a volume of water and a submerged object of the same volume is the same. Since it exactly supports the volume of water, it follows that the buoyant force on any submerged object is equal to the weight of the water displaced.
How is weight different than mass?
Mass is a measure of how much force it will take to change that path. Mass depends on how much matter – atoms and so on – there is in an object; more mass means more inertia, as there is more to get moving. Weight, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object.
What does the buoyant force depend on the mass of the object or its volume or its density or the material from which it is made?
The mass displaced depends on the volume of the object and local density of the fluid. Thus, if the fluid is compressed, but the submerged object compresses less, the displaced mass increases, increasing the buoyant force.
Is the buoyant force the same for all objects?
The buoyant force being equal to the weight of the liquid displaced it is same for different bodies. The buoyant force acting on an object is proportional to its volume and to the density of the fluid in which it is submerged. If the volume of both metals is the same, they will experience the same buoyant force.
How does the mass of the liquid displaced compare to the mass of the object?
An object heavier than the amount of the fluid it displaces, though it sinks when released, has an apparent weight loss equal to the weight of the fluid displaced. In fact, in some accurate weighing, a correction must be made in order to compensate for the buoyancy effect of the surrounding air.
