What many people don't know, though, is that scuba diving would be impossible without physics.  Pressure, buoyancy, and force are big parts of diving.
     Pressure, the weight pushing on something, is a vital part of scuba diving.  As a diver sinks deeper into the water, the pressure pushing on the person's lungs pushes harder.  This can be very dangerous to a person's safety.  While the water is pushing on the outside of the lungs, pressure in the inside of the lungs is pushing out.  If this pressure isn't the same as the weight from the water pushing on the lungs, the diver could have breathing problems and possibly die.  To equalize these two pressures, modern scuba gear is equipped with a device attached to the air hose called a demand regulator that controls the flow of air getting to the lungs, changing the pressure inside.
     Buoyancy, how easily a person sinks or floats, is definitely a huge part of scuba diving.  It determines how deep a person stays underwater.  To control this, divers wear weights and inflatable neckwear called buoyancy compensators.  Depending on how many weights a person is wearing; they ...
