# What does the Archimedes Principle State?

## What does the Archimedes Principle State?

Archimede’s Principle states that a body immersed in a fluid experiences an upthrust equal to the weight of the fluid displaced, and this is fundamental to the equilibrium of a body floating in still water. A body floating freely in still water experiences a downward force acting on it due to gravity.

## What is Archimedes Principle Why does an object sink or float when placed on the surface of water?

Answer: An object float or sink when placed on the surface of the water because, An object floats in water if its density is less than that of water. When the object’s weight force is balanced by the upward push of the water on the object.

What does Archimedes Principle State explain what force if felt when you dive in a pool of water?

Archimedes’ principle states that the buoyant force on an object equals the weight of the fluid it displaces. Specific gravity is the ratio of the density of an object to a fluid (usually water).

What is Archimedes Principle class 11th?

Archimedes’ principle states that: “The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid”.

### Why do objects float in water?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. The upwards push of the water increases with the volume of the object that is under water; it is not affected by the depth of the water or the amount of water.

### Why do objects sink in water?

Whether an object floats or sinks in water depends on how dense, or compact, its particles are. An object will sink in water if it is made up of particles that are more tightly packed together than the particles in water. An object that is less dense than water will float.

What do you mean by buoyancy Why does an object float or sink?

Forces acting on the body inside water are buoyant force and weight of the body. If the buoyant force is greater than the gravitational force then the body floats, otherwise it sinks.

Why does an object float or sink?

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

#### When the object is denser the object will?

An object that has a higher density than the liquid it’s in will sink. An object that has a lower density than the liquid it’s in will float. You can really see relative densities at work when you look at a heavy object floating and a lighter one sinking.

#### Why do boats float Archimedes Principle?

Archimedes’ Principle states that the force exerted on an object in a fluid is equal to the weight of fluid displaced (moved out of the way) by the object. This force is called buoyant force. So if the force exerted downward on the object by gravity is less than the buoyant force, the object will float.

How is the Archimedes principle related to fluid mechanics?

e Archimedes’ principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes’ principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.

How did Archimedes explain the principle of buoying up?

As he waded into deeper water, the force on his feet became less. Archimedes’ Principle is that an object totally or partially immersed in a fluid (liquid or gas) is buoyed (lifted) up by a force equal to the weight of the fluid that is displaced.

## What was the principle of archimedes’second book?

Archimedes: His works. …come to be known as Archimedes’ principle: a solid denser than a fluid will, when immersed in that fluid, be lighter by the weight of the fluid it displaces. The second book is a mathematical tour de force unmatched in antiquity and rarely equaled since.

## How is thrust force determined in the Archimedes law?

The value of thrust force is given by the Archimedes law which was discovered by Archimedes of Syracuse of Greece. When an object is partially or fully immersed in a liquid, the apparent loss of weight is equal to the weight of liquid displaced by it.
