Page 2: Fundamental Hydrostatic Equation

This page delves deeper into hydrostatic pressure and its fundamental equation, explaining how pressure varies with depth in liquids.

Definition: The fundamental hydrostatic equation states that pressure at any point in a liquid equals the product of depth, liquid density, and gravitational acceleration.

Example: A calculation demonstrates finding pressure in a liquid with density 0.8 g/cm³ at 65 cm depth, yielding 5,200 Pa.

Highlight: Forces on submerged bodies are always perpendicular to any surface within the liquid.

Vocabulary: Hydrostatic paradox - The phenomenon where pressure at the bottom of containers depends only on liquid height and base area, regardless of container shape.

Page 5: Archimedes' Principle and Buoyancy

This page explains Archimedes' principle and its applications in understanding buoyancy.

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

Example: Detailed calculations show the relationship between buoyant force, object weight, and resulting motion.

Highlight: Three cases of equilibrium for submerged objects are presented based on the relationship between weight and buoyant force.
