## What is the condition for an object to float or sink?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.

**What are the conditions for Archimedes Principle?**

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. We consider that the above force, called force of buoyancy, is located in the centre of the submerged hull that we call centre of buoyancy.

**What is Archimedes Principle and floatation?**

When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation”: A floating object displaces a weight of fluid equal to its own weight. Archimedes’ principle, as stated above, equates the buoyant force to the weight of the fluid displaced.

### What is the condition for floating?

So general, the floating condition is that density of the object should be smaller than the density of the fluid. It’s not just for water. It can be for any liquid or gas.

**What are the conditions of flotation?**

Condition for Flotation. An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. When any boat displaces a weight of water equal to its own weight, it floats.

**How is density used to determine whether a material will float or sink in liquid?**

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.

## What is the condition in which the buoyant force on an object does equal the weight of the object?

But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the object’s weight.

**How does Archimedes Principle relate the buoyant force acting on an object to the fluid displaced by the object?**

How does Archimedes’ principle relate the buoyant force acting on an object to the fluid displaced by the object? The volume of water displaced by an object is equal to the volume of the object. If the weight of the object is greater than the BUOYANT FORCE, the net force of a SUBMERGED object will be downward.

**Which of the following represent the condition for floatation?**

### Under what condition an object having density greater than water will float on water?

Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

**In which of the following conditions the body will sink in the liquid?**

1. if the density of the body is higher than the density of liquid,then it would sink. 2, if the density of body is less than the density of liquid,then it would float.

**What is the condition under which an object will sink in a liquid?**

## What is buoyant force and Archimedes principle?

But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the object’s weight.

**What is the principle of Floatation?**

Principle of Flotation: Definition. For an object that is completely submerged in a fluid, the weight of the fluid displaced by it is less than its own weight. On the other hand, for an object that floats on the surface of the fluid, the weight of the fluid displaced by it, is equal to the weight of the object.

**What force causes an object to float or sink?**

There is an upward force, or buoyant force, on any object in any fluid ( (Figure) ). If the buoyant force is greater than the object’s weight, the object rises to the surface and floats. If the buoyant force is less than the object’s weight, the object sinks.

### How do you know if an object will float or sink?

If the volume of the object weighs less than the same volume of the fluid it is displaces (is immersed in), it floats. if the weight of the object is heavier than the volume of fluid it displaces, it sinks. If it weighs the same it has ‘neutral’ buoyancy and will either sink or float without additional being pushed.
