Diving Physics
Understand the physical principles that make scuba diving possible: atmosphere and water pressure, bar and psi, absolute and gauge pressure, air and breathing gases, density, buoyancy and Archimedes’ principle, the major gas laws, partial pressures and gas solubility, gas consumption and breathing resistance with depth, Venturi and flow effects, light and vision through a mask, sound underwater, temperature and heat transfer — followed by practical calculations that connect these principles to real diving.

KCore educational note: Physics examples are simplified learning models. Real diving conditions, physiology, equipment and procedures are more complex; use this material to understand principles, not as a substitute for recognized diver training, supervised practical instruction, current procedures or conservative dive planning.
