Why a cork floats on water surface but an iron nail sinks in it?

The density of cork is less than the density of water. This means that, the upthrust of water on the iron nail is less than the weight of the nail. So it sinks. Therefore if density of objects is less than liquid it will float on the liquid.

What is the net force on a cork floating on water?

When a cork floats freely on water, the weight of the cork is balanced by the upward buoyancy. So, the net force is zero.

What will be the buoyant force acting on a piece of cork when it floats on water surface?

When a piece of cork is put into the water it starts floating on the surface of water due to the upward buoyant force from water because density of water is more than the density of cork.

Why does an iron nail sink in water but a leaf does not?

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.

Why does stone sink in water?

A stone is more dense than water. That is, if you compare the mass of a stone to the mass of the same volume of water, the stone’s mass will be greater. Therefore the stone will move downward through the water until it rests on the bottom.

What is the net force on a piece of wood floating on water?

Zero
Zero, because the weight of the wooden piece is balanced by the upward thrust or buoyancy of the liquid.

What is the buoyant force on the cork after you release it?

According to Archimedes’ principle, the buoyant force acting on the cork is 124.8 pounds, which is greater than the weight of the cork. Therefore, if the cork is released the buoyant force pushes it to the surface, where it remains partially immersed.

What force is acting between the water and the cork causing the cork to move?

It is thus called a centripetal force; “centripetal” means “center-seeking.” This demonstration illustrates this force in a striking and, perhaps, counterintuitive way. The inverted bottles with floating corks are a type of accelerometer.

Why do objects like metals or stones sink in water?

Objects like Stone and metals have density greater than the density of water, therefore they sink in water.

Does iron float in water?

Iron is much denser than water. A solid chunk of iron sinks, as you would expect, but an iron ship floats.

Does stone sink or float?
