# What does buoyancy mean?

Do you know when we fall from a boat then what will happen to our body; yes, we know that we would be sinking in water. This explanation is given by Archimedes’ principle. The principle of Archimedes gives a complete description about the cause of floating or sink of objects. He explains us that what will happen to our body. He found that water pushes in the upward direction opposite to object and this force is equal to the weight of displaced water.

When an object is in the water then it displaces some amount of water according to its weight. The amount of displaced water is calculated by objectƒ¢¢€š¬¢€ž¢s density which relates to volume. The volume of a cricket ball and beach ball can be same their different weight their density is differed. The steel solid block sinks in water but the steel ship does not. Thus the amount of displaced water in the upward direction is explained in terms of Buoyancy force . Letƒ¢¢€š¬¢€ž¢s discuss about the buoyancy force and its formulation with its different devices based on it.
