What happens to an inflated ball as it is submerged deeper underwater?

As an inflated ball is submerged deeper underwater, the buoyancy it experiences increases due to the principles of fluid dynamics, specifically Archimedes' principle. This principle states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces.

As the ball goes deeper, it displaces more water, resulting in an increase in the buoyant force acting on the ball. However, it's important to note that while the buoyancy increases, the hydrostatic pressure acting on the ball also increases due to the weight of the water above it. This pressure can affect the ball's volume if it's not rigid enough to withstand the pressure or if there is a small amount of compressibility in the material.

In any case, as depth increases, the displaced volume of water—and, therefore, the buoyant force—also increases, making the buoyancy effectively greater. This understanding of fluid dynamics helps explain why the buoyancy of the ball increases as it is submerged deeper underwater.
