How do boats float?🤓

 

Things float because, they are less dense than water.

When a object is immersed in water, its weight pushes it down.

At the same time, the water pushes it back, with a force equal to the weight of water displaced.

The upward push on a floating object is called buoyancy.

Buoyancy Explained

Objects, which are denser than water sink when the weight of the object is not equal to the upward push of water.

The water offsets the force of gravity, which tries to pull everything to the centre of the Earth. 

How do boats float?

This is how boats float.

Steel ships float on the same principle. 

Although, steel is denser than water yet, the hull of a steel ship is full of air.

The ship floats, till enough water is displaced to match the weight of steel and air in the hull.

Structure of a Ship

Several key components make up the main structure of most boats.

The hull is the main structural component of the boat which actually provides buoyancy for the boat.

The keel is a lengthwise structural member to which the frames are fixed.

FunFact:-

The Titanic, was believed to be unsinkable. But, as soon as iceberg breached her hull, water entered to replace the air, which made her sink.
