Archimedes’ principle states that
a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid
. This is a first condition of equilibrium.
Which is the best explanation of Archimedes principle?
Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that
any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force
, the magnitude of which is equal to the weight of the fluid …
What is Archimedes principle explain with example?
Archimedes’ Principle : When a solid body is partially are completely immersed in a fluid, the fluid exerts an upward force on the body, whose magnitude is equal to the weight of the displaced fluid. … Example,
a ship floats on water
due to the Archimedes principle.
What is the lesson of Archimedes principle?
Lesson Summary
Archimedes’ principle, named after an inventor and a mathematician who lived in ancient Greece, states that
the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object
. Buoyancy is the ability of an object to float in water or air.
Why does Archimedes principle work?
The reasoning behind the Archimedes principle is that
the buoyancy force on an object depends on the pressure exerted by the fluid on its submerged surface
. Imagine that we replace the submerged part of the object with the fluid in which it is contained, as in (b).
Where do we use Archimedes principle in daily life?
1.
On entering a bathtub filled with water, an equal quantity of water is displaced as the weight of the person
. 2. A ship floats in the sea because of the buoyant force acting from the water.
What are the two applications of Archimedes Principle?
The applications of Archimedes’ principle are: (i) Archimedes’ principle is used in designing ships and submarines. (ii)
Lactometers based on Archimedes’ principle are used to measure purity of a sample of milk
. (iii) Hydrometers used to measure density of liquids are based on Archimedes’ principle.
How do you prove Archimedes Principle?
Proof:
Consider a body of height h and area of cross-section A placed in liquid of density σ at a depth x below the free surface
. Let ρ be density of the body. where P
0
is atmospheric pressure. Body will experience the net force F
2
– F
1
in upward direction known as upward thrust.
Why do ships float on water?
The air that is inside a ship is much less dense than water
. That’s what keeps it floating! … As a ship is set in water, it pushes down and displaces an amount of water equal to its weight.
Why do higher density objects sink?
If the object is
denser than water it is more massive than the water that it displaces
. This means that the object experiences greater gravitational force than the water and so sinks.
Is water the only fluid that can provide buoyancy?
If an object floats in water, the weight of the water displaced is greater than the weight of the body immersed in water. …
Water
is the only fluid that can provide buoyancy.
What is buoyancy explain with example?
The definition of buoyancy refers to whether something can float in water or air, or the power of water or other liquids to keep water afloat, or an optimistic disposition. An example of buoyancy is
when a boat floats in water
. An example of buoyancy is when salt water has the ability to help things float.
What are the factors that influence buoyancy?
- The factors that affect buoyancy are… the density of the fluid. the volume of the fluid displaced. the local acceleration due to gravity.
- The buoyant force is not affected by… the mass of the immersed object. the density of the immersed object.
What are some applications of Archimedes Pascal’s and Bernoulli’s principles?
The concepts of Pascal’s law, Archimedes’ principle and Bernoulli’s principle are important in engineering
and technology applications such as aerodynamics and hydrodynamics, hydraulics, floating vessels, submersibles, airplanes, automobiles, aerospace guidance and control, pipelines and transport systems, as well as
…
What are the application of floatation?
Following are some application of principle of floatation:
Floating of ships. Submarines
: Ballast tanks in submarine is filled with sea water so that it sinks. Icebergs floating on water.
What are fluids Why is Archimedes principle applicable only for fluids give the application of Archimedes Principle?
Archimedes principle is applicable only for fluids because:
Only fluids exert buoyant force
. An object cannot be immersed in a solid, but it can be immersed in a fluid.
