The term "centre of flotation" refers to the point above water where an object is displaced and buoyant force acts on it. Some synonyms for this concept may include "buoyancy center," "flotation center," or simply "center of buoyancy." Other related terms may include "metacenter," which refers to a point where a floating object will naturally rotate when disturbed, and "displacement volume," which relates to the amount of water displaced by an object when it floats. Regardless of the specific term used, understanding the concept of the center of flotation is crucial for engineers and designers working with flotation devices or aquatic vessels.
