How do ships float?

Have you ever played throwing pebbles to a body of water like the pond or the beach? From that act, we can observe our thrown pebbles sinking. So, how could a heavy steel ship be able to float in the water when a small pebble cannot?

Well, thanks to Archimedes we are now enjoying the benefits of floating ships. Archimedes was a Greek Scientist and mathematician in the Third Century B. C. He noticed how the water level rose as he immersed his body in a bathtub. When he was able to understand this phenomenon, he immediately rushed to tell the people. And yes, he was the scientist who shouted ‘Eureka! Eureka!’ or it means “I have found it”.

The principle that he was able to established is called the Archimedes principle or mostly known as the Buoyancy. It was named based on the Spanish translation of float, which is boyar. By definition, Buoyancy is the force acting upon an object making that object rise or move upward. Aside from that, this principle states that in order for the objects to float, the buoyant force exerted on an object in a fluid must be equal to the weight force of the displaced fluid. In simpler words, the applied downward force on the object, determined by its weight (mass x gravity), must be equal or lesser than the buoyant force in order for the object to float.
