If we throw a lump of iron weighing just 1 kilogram into water, itโll immediately sink. So how can ships that weigh thousands of tons float on water?
Whether an object floats or sinks depends on two forces: the buoyant force of the fluid and gravity. The buoyant force is the upward force that a fluid exerts on an object, while gravity is the downward force. If we think about the difference between these two forces we can write down a formula: buoyant force minus gravitational force = (density of fluid โ density of object) x gravitational acceleration x the volume of the object.
If the buoyant force minus the gravitational force is zero, the object will float. It may float with part projecting above the fluidโs surface or fully submerged at the surface. If an object that can float is pushed below the surface, the buoyant force will temporarily exceed gravity and cause the object to rise to the surface again. If the buoyant force minus gravity is than zero that means the upward force acting on the object is smaller than the gravitational force and so the object will sink.
The only thing that determines whether buoyancy minus gravity is positive, negative, or zero is the density of the fluid and the average density of the object. If the density of the fluid is greater than the average density of the object then the object will float.
In the case of a ship, itโs made of tons of steel, but the shipโs hull is hollow with lots of empty spaces filled only with air. Because the density of air is very low, these spaces mean that the average density of a ship, even one weighing many thousands of tons, is lower that the density of water. And thatโs the reason that ships can float.
