With some knowledge of physics, one can answer all of these questions. I will now explain how physics makes scuba diving possible, and why physics is integral to the following topics of scuba diving:
These are also some of the main topics covered in a certification course. If you are interested in learning how to scuba dive, it will be necessary to know about these topics and the basic physics behind them.
