# How does the buoyant force on an object relate to the fluid around the object?

## How does the buoyant force on an object relate to the fluid around the object?

Archimedes’ principle is the statement that the buoyant force on an object is equal to the weight of the fluid displaced by the object. The simplicity and power of this idea is striking. If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object.

How is the buoyant force related to the mass of the displaced fluid?

In simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g.

### How does Archimedes Principle relate to geometry?

Archimedes’ principle is very useful for calculating the volume of an object that does not have a regular shape. The oddly shaped object can be submerged, and the volume of the fluid displaced is equal to the volume of the object. When the object is submerged, it weighs less because of the buoyant force pushing upward.

How does the buoyant force that acts on a fish compare with the weight of the fish?

The pressure on the bottom of the object is greater than the pressure on top. How does the buoyant force that acts on a fish compare with the weight of the fish? The buoyant force and the weight of a fish are the same. The density of the object is less than the density of water.

## Why does the buoyant force always act upward quizlet?

Why does the buoyant force act upward on an object submerged in water? Because the weight of the object, that is the gravitational force on the object will be directed downwards. This weight on the water pushed the water downwards. The volume of the completely submerged object is equal to the volume of displaced water.

How does the Archimedes principle relate to buoyancy?

Since this weight is supported by surrounding fluid, the buoyant force must equal the weight of the fluid displaced. Archimedes’ principle refers to the force of buoyancy that results when a body is submerged in a fluid, whether partially or wholly.

### How is the buoyant force related to the weight of the fluid?

The buoyant force on an object equals the weight of the fluid it displaces. In equation form, Archimedes’ principle is where F B F B is the buoyant force and wfl w fl is the weight of the fluid displaced by the object.

Which is true about archimedes’principle of upthrust?

Archimedes’ principle states that the upthrust or buoyant force on an object in a fluid is equal to the weight of the displaced fluid. Displaced means pushed out of the way, so for instance when you drop stones into a container of water, you displace the water and it rises in the container. A force can be though of as a push or pull.

## When is the buoyancy of an object always present?

If the buoyant force equals the object’s weight, the object can remain suspended at its present depth. The buoyant force is always present, whether the object floats, sinks, or is suspended in a fluid. The buoyant force is the upward force on any object in any fluid.
