Principle of Archimedes: Examples and Experiments

This lecture covers the principle of Archimedes, focusing on the upward pressure forces in static fluids, known as Archimedes' thrust. It explains how the pressure forces remain constant when replacing an immersed fluid piece with another object of the same volume. The lecture also discusses scenarios where a body submerged in a fluid experiences different forces, such as equilibrium, sinking, or floating. Various examples, including a fairground balloon and a fluid-filled container on an accelerating cart, are used to illustrate the concept.
