## What is Archimedes law of buoyancy?

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 the principle of fluid displacement?

The amount of fluid displaced is directly related (via Archimedes’ principle) to its volume. In the case of an object that sinks (is totally submerged), the volume of the object is displaced. In the case of an object that floats, the amount of fluid displaced will be equal in weight to the displacing object.

#### How can Archimedes principle be used to find density?

To calculate the coin’s density, we need its mass (which is given) and its volume. The volume of the coin equals the volume of water displaced. The volume of water displaced Vw can be found by solving the equation for density ρ=mV ρ = m V for V.

How does the Archimedes principle apply to ships?

Archimedes’ buoyancy principle states that buoyant force — what keeps the ship afloat — is equal to the weight of water that is displaced when the ship enters the ocean. If the weight of displaced water is at least equal to the weight of the ship, the ship will float.

How does Archimedes principle explain whether an object will float or sink in water?

Answer: If the buoyant force is greater than the object’s weight, the object will rise to the surface and float. If the buoyant force is less than the object’s weight, the object will sink. Archimedes’ principle states that the buoyant force on an object equals the weight of the fluid it displaces.

## How do you calculate Archimedes principle?

If an object is completely submerged,the volume of the fluid displaced is equal to the volume of the object.

• The buoyancy force on hot-air balloons,dirigibles and other objects can be calculated by assuming that they are entirely submerged in air.
• The buoyancy force does not depend on the shape of the object,only on its volume.
• ### How do you prove Archimedes principle?

When a body is partly or completely immersed in water,it loses weight.

• A body loses its maximum weight when it is completely immersed in water.
• When a body is partly or completely in water then:
• #### What are the three applications of Archimedes principle?

Using Archimedes law,the volume or density of any rigid body can be computed.

• Submarines operate using the Archimedes theory.
• Ships are made hollow such that the effective density is less than the density of water.
• The densities of liquids are computed using hydrometers which work according to the Archimedes principle of buoyancy.
