## What are the conditions required by an object to float on a liquid?

For an object to float on water, mass of the object must be equal to the mass of liquid displaced by it. Or the overall density of the object must be less than or equal to the density of liquid in which it has to float.

## What are the rules for floating and sinking according to Archimedes Principle?

Answer: Buoyant force is the net upward force on any object in any fluid. 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.

## What is Archimedes Principle regarding 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 difference between Archimedes principle and law of floatation?

Archimedes principle is based on the weight of the object to push the object upward. ​Law of floation is the priciple which tells us about the density of the object with the liquid in which it is placed.

## What are the laws of floatation?

The principle of floatation states that when an object floats on a liquid the buoyant force that acts on the object is equal to the weight of the object. Following are the pointers to remember in floatation: The displaced volume of fluid is equal to the volume of the object which is immersed in the fluid.

## Why does a ship float and a nail sink?

As most of the space in the boat is taken up by air so it causes the overall density of boat to be lesser than that of water. Whereas, the density of the iron nail is more than that of water. Due to this the iron nail sinks while the boat floats on the surface of the water.

## What is floatation and sinking?

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 factors that affect sinking and floating?

The shape, weight, volume, density, porosity and water displacement also factor in to its floating ability. A steel boat, for example, will float while a steel bar will sink because of the density compared to the amount of water and also because of the form/shape the object is in.
