ft theory and is revisiting (Charles) Silvia's ideas" (Adams, 2000). It is therefore in question whether lift theory is important to swimming and if so, how important is it?The law of inertia states that a force is needed to move a body at rest, to stop a body that is moving or to change the direction of a moving body. The law of inertia affects aquatics in two aspects. First static inertia is the tendency of a body at rest to stay at rest. Swimmer must overcome every time he or she enters a pool because the static inertia of the water will resist any effort change position. Secondly, dynamic inertia is the tendency of a moving body to keep moving. To overcome the law of inertia, swimmers must possess energy to complete a stroke to keep moving. Furthermore, dynamic inertia lets swimmers rest because your body is moving. However, if one rest to long during dynamic inertia, one might have to overcome static inertia.The law of acceleration states that the speed of a body depends on how much force is applied to it and the direction of that force. The law of acceleration is relevant in swimming in two ways. First, the more force you apply to a stroke, the faster a swimmer will swim. Second, swimming is more efficient when a swimmer chooses to stay in a chosen direction when all your propulsive force is in the same direction.The law of action and reaction states, that for every action there is an equal and opposite reaction. Reaction and action can occur in water and land. For instance, if a ball drops into a bucket of water, the ball stops in the water and the water will project from the bucket. Thus, it is creating an action and reaction from the ball. A second example, when one dives from a diving board, the board reacts to the force of your feet acting against it so you can take off for the dive.The law of levers is the product of force and force arm is equal to the product of the resistance and resistance. The law of leve...
