How Newton's Laws Effect Swimming
History of Swimming
Newton's First Law
Newton's first law says that a object in motion stays in motion and an object at rest stays at rest unless acted on by another force. This relates to swimming because when a swimmer pushes off of a wall, they will feel a force or a drag as they move through the water. Also, the swimmer could keep moving through the water forever but the drag will eventually slow them down.
Newton's Second Law
Newton's second law says that the acceleration of two objects depends on 2 variables, the net force and mass of an object. This law helps people understand why some people move faster then others. An example is when 2 people with the same mass both push off a wall at the same time and didn't take any strokes, the person who used the most force would go farther. The acceleration was bigger for the person who used the greatest force because both of the masses were equal.
Newton's Third Law
Newton's third law says that for every action there is a equal and opposite reaction. An example relating to swimming is when you pull water down to your side, the water moves down to your feet while you are moving forward. The action is moving your arm in the water and the equal reaction is the water pushing back on you. The opposite reaction is the reason the forward movement happens.
