Buoyancy
Buoyancy is the upward force exerted by a fluid on an object that is partially or completely submerged in it. In maritime context, buoyancy is a crucial concept for understanding the behavior of ships and other floating vessels. The buoyancy of a ship is determined by its displacement, which is the weight of the water that the ship displaces when it is floating. The buoyancy force must be greater than the weight of the ship in order for it to float. This is why ships are designed with a specific shape and size to ensure that they displace enough water to generate the necessary buoyancy force. Buoyancy is also important for understanding the stability of a ship, as it affects how the ship responds to waves and other external forces.
