Sky Diving



It is the one that is opposed to the movement of an object that is this moving in the air. It depends on two factors; the speed of the object and the aerodynamic form of the object. It is the resistance that is generated to rub shoulders with the air, in this point the gravit force is major that the resistance on his body and because of it it accelerates. As it accelerates, it increases the resistance because while more rapid an object moves in the air, major it is the resistance. With the parachute opened on his head, the parachute present a surface area that is very much major for the air for which they move, which increases considerably the resistance. Since the ascending force now is major that the descending force, suddenly it begins to reduce the speed. As it moves more and more slow, the resistance diminishes until the gravity and the resistance return to be equal
