# What is buoyant force?

Posted Date:     Total Responses: 0    Posted By: C.N.Anantharaman   Member Level: Gold   Points/Cash: 2

Those substances which flows easily are called fluids.A fluid exerts pressure in all directions.When an object is placed in a liquid,the liquid exerts a upward force or upthrust which is called buoyancy.

Objects appear to be less heavy when submerged in water.Every liquid exerts an upthrust on the objects immersed in it.The tendancy to exert an upward force on an object by a liquid is called buoyancy.It is also called Upthrust.

It is the buoyant force which makes heavy objects feel lighter in water.

The pressure exerted by a liquid increases with depth and acts in all directions.

The maximum loss in weight of an object takes place when an object is fully immersed in a liquid.

Factors that affect buoyant force are as follows:-

(1)Volume of the object immersed in the liquid.

(2)Density of a liquid.

When an object is placed in a fluid, the fluid exerts an upward force we call the buoyant force. The buoyant force comes from the pressure exerted on the object by the fluid. Because the pressure increases as the depth increases, the pressure on the bottom of an object is always larger than the force on the top - hence the net upward force.

The buoyant force is present whether the object floats or sinks. Let's consider a floating object, but the analysis is basically the same for a submerged object.

We'll also consider a rectangular block, although a similar (more complicated) analysis leads to the same result for funny-shaped objects.

Hi,
I have a question, Let say if i have a object of size 1 cubic foot( made of plastic) with air filled in it.

i have a water tank with infinity depth, let say i introduce the object at the depth of the 1 meter. it will come to the surface.
let say if i introduce it in 10 meter will it come to the surface?
when does the the same object will sink, i mean after some distance it should sink right ?
thanks
mnathan
