Answer» Answer: n all diving operations, safety is the primary considera- tion. One key to safety is a clear understanding of the physics of diving. Physics is the FIELD of science dealing with matter and energy and their interactions. This CHAPTER explores physical laws and principles that pertain to the diving envi- ronment and its influence on the diver. Gravity is passive, vision and hearing may be misleading, color perception changes at varying depth, and BREATHING dynamics are ever changing. The principles of physics provide the keystone for understanding the reasons for EMPLOYING various diving pro- cedures and the operation of associated equipment. Many of these principles receive further elaboration in other sections of the NOAA Diving Manual. 2.1 PRESSURE Pressure is FORCE acting on a unit area. Stated mathemati- cally, Pressure = force/area P = F/A |
