hydrostatic stability

Hydrostatic stability refers to an object's ability to remain balanced and upright when submerged in a fluid, like water or air. It depends on how the object's weight distribution and shape interact with the fluid's buoyant force. If the center of gravity (where the weight acts) is low and the center of buoyancy (the point where upward force from the fluid acts) is appropriately positioned, the object stays stable and resists tipping over. Essentially, a hydrostatically stable object naturally returns to its original position after being tilted, thanks to the balance of these forces and centers.
