Titanic

The movie that amazing for me is TITANIC. This movie is based on real story and the ending so sad.It starts Leonardo Dicaprio(jack) and Kate Winslet (rose) who fall in love abroad the ship during its ill-fated maiden voyage. This movie have many related to physics one from that is how the big ship can float in the sea without submerged. In our logic,something that are bigger will submerged when throw in the sea,but why ship called titanic not submerged. Now I will explain why it not submerged. This is because all this is related to the buoyant force for example,when we throw something into the water it will reject and replaced the water content. For example ,when we put a tennis ball into the glass,tennis ball as much water will split out.If the weight of the displaced water is heavier than the weight of a tennis ball,the ball will float.If the ball is filled with metal as compared with air,it would be heavier than the contents replaced with water and it will float.The man who discovered the theory is Archimedes is known as the father of the theory of the float who discovered it while in the bath tub.So we know why the ship titanic not submerged even it bigger.
