Why Don’t Ships Sink?


By: Tamanno Alimova

Have you ever wondered, how something as huge and heavy as a ship doesn’t sink in water? Well, if you were wondering, it’s because of density. Density is the compactness of a substance. The water’s density is 1 g/cm cubed. It doesn’t matter how big or small the object is. All that matters is if the object is more or less dense than water. If the object is more dense than it will sink. If it’s less dense than it will float.

It’s also because of displacement. Displacement is when an object displaces, or pushes aside water. When something is placed in the water, the water displaces, therefore it does not matter how heavy the object is because, the water that is pushing aside weights the same as that object. Ships are designed to displace as much water as possible, so that they do not sink. A ship also has a lot of empty space , which allows it to keep it light compared to the huge amount of water that it’s displacing.

Why ships float is related to engineering, because this is how you apply physical properties of elements in the real world. You have to know how this stuff works in order to build it. A lot of different engineers work together to build these different types of ships. This is why and how ships float, and do not sink.
