Overview
Buoyancy is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the object.
💡
Pro Tips
The force depends ONLY on the volume of the object submerged and the density of the fluid.
If the buoyant force is greater than the object's weight, the object will float.
Density of fresh water is approximately 1000 kg/m³.

Fun Facts
"Archimedes discovered this principle while taking a bath, reportedly shouting 'Eureka!'."
"Steel ships float because they are hollow, so they displace a volume of water that weighs more than the ship itself."
"The Dead Sea is so salty (dense) that people float effortlessly on its surface."
