Why do Objects float?

All object have mass, thus it makes up a space. Any object that has mass has also its density. Density of an object is defined as mass per unit volume.

The density of an object is important to find out if it can float on water or not. An object floats because it is less dense than water. Any object that floats is always denser with the liquid where it floats.

Take for example a human being on a swimming pool. A person who could not swim can still float because its mass is lighter than the water in the pool combined. This is the reason why people who could not swim should not be afraid of sinking in a pool or ocean because eventually, he will just float because the body of water is heavier.
Another reason why objects float is its buoyancy. Buoyancy is defined as the upward force exerted by the fluid that resists the object’s weight. There are some objects that do not float because of its dense and the buoyancy principle. Sometimes, the shape of an object can be a factor why it sinks. Take for example the stone, although it is small, it still sinks in the ocean. This is because the fluid could not resist the weight of the stone. Its downward gravity is too strong that the water could not pull it up and let it float.
In the case of the ship, it is designed and shaped for it to float in water. It is engineered in a way that it becomes less dense as compared to the water where it floats. The buoyancy principle is also applied wherein the accelerating downward force can be resisted by the body of water where the ship floats. The ocean has enough water to carry the entire weight of the ship.
