Scuba :: essays research papers

Scuba go down is an activity enjoyed by people all over the world. Scientists use it to chew over underwater life, police use it to train in case of emergencies, and to a greater extent others do it just for fun. What many people dont know, though, is that scuba diving would be impossible without physics. Pressure, buoyancy, and force are big divulges of diving. Pressure, the weight force on something, is a vital part of scuba diving. As a diver sinks deeper into the water, the pressure pushing on the somebodys lungs pushes harder. This can be genuinely dangerous to a persons safety. While the water is pushing on the alfresco of the lungs, pressure in the inside of the lungs is pushing out. If this pressure isnt the same as the weight from the water pushing on the lungs, the diver could have breathe problems and possibly die. To equalize these two pressures, modern scuba gear is furnished with a device attached to the air hose called a need regulator that controls the flow of air getting to the lungs, changing the pressure inside. Buoyancy, how slow 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(prenominal) wear weights and inflatable neckwear called buoyancy compensators. Depending on how many weights a person is wearing they sink to a certain depth and stay there. The more weights, the farther down they go. The buoyancy compensator, once inflated, rises the person back up to the surface. The more accessories, such as weights, a person wears, the lighter they experience in water and the easier they sink. All kinds of forces can be associated with scuba diving. For instance, when a diver kicks his fins to move, he is applying a force on the water back end him. In turn, the water is applying a force back on him, do him to move. Pressure is a force that pushes on a divers lungs, air tank, and everything else in the water.
