It's a common swimming pool game: Force a buoyant ball underwater ... particle image velocimetry to describe why buoyant spheres ascending through a fluid don't always behave the way we expect ...

Let’s break it down in simple terms. Buoyancy is the upward force that water (or any fluid) exerts on an object placed in it. According to Archimedes’ Principle, when an object is submerged in ...

Fluid statics: buoyancy, hydraulic jack, force on a submerged plate, manometry Fluid Dynamics: force of a fluid jet, drag on a cylinder in a wind tunnel Pipe Flow: frictional losses in pipes, pressure ...

The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature.

Consequently, while it was floating, the ball should have displaced the same amount of water as it decreased in diameter, and so the buoyant force should have remained the same. However ...
