Welcome to Physics class!  One of the questions we hear often is "how long will we be able to stay down on this dive?"  This is a difficult question to answer with all of the factors involved, but we can estimate! Fundamentally, this concept is the Pressure, Volume, Density relationship. There are many things in scuba that refer back to this relationship in our underwater environment. If we break down the three definitions first, we can then look at how they apply to scuba divers.  Pressure - This is the force per unit area of the object on which the...
