5. Buoyancy and Archimedes’ Principle

Buoyancy and Archimedes’ principle explain the upward force exerted by fluids on objects immersed within them, demonstrating various factors that affect this force, including the object's volume and the fluid's density. Key concepts include buoyant force, Archimedes’ principle, and density, relevant to practical applications such as shipbuilding and measurement of purity. The chapter further discusses the law of flotation, outlining how weighted bodies interact with the fluids they displace.

    Archimedes’ Principle

    Archimedes' Principle states that a body immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced.
