Marathon Swimming
Marathon swimming is a 10 km race in open water like the ocean. First the origin of this sport started in 1875, when Captain Matthew Webb was the first person to cross the English channel. Second, the rules of this sport are that you cannot hold on to anything for support, like buoys or boats. You can not draft behind a person. If the people on the support boat drop nutritional gel into the water the swimmer can eat it, but they cannot go up to the boat and hold it or else they will get disqualified. Lastly the equipment for the sport is swimsuit, swim cap, goggles, earplugs, nose clips, sunscreen, watch, escort boat. Marathon swimming became part of the Olympics in 2008 in Beijing, China. Olympic Marathon swimming also shows Newton’s Laws.
Newton's first law of motion is if there is an object at rest it will stay at rest, unless an unbalanced force is applied. An object in motion will stay in motion, unless an unbalanced force is applied. Balanced forces is when forces are pushing the opposite directions and with the same amount of push. If an unbalanced force is applied when an object is moving, it will stop. If an unbalanced force is applied when an object is stopped, it will move. In marathon swimming, the rest is in the swimmer when they stop. That is Newton’s first law of motion in marathon swimming.
Marathon swimming applies to Newton's 2 law in several ways. Forces in the sport of swimming are muscular forces because when their arms come down they push the water. Also, buoyant forces in my sport are the water. The mass is the swimmer and the support boat because it has a lot of matter. Acceleration is the waves because the waves push you forward and it accelerates you until you reach your max speed. Acceleration is also the swimmer when they swim to the shore. When the swimmers apply more force with their arms and legs, they accelerate faster. These are the many ways Newton's second law interacts with Marathon swimming.
This is Newton's 3rd law in marathon swimming . Every action has an equal and opposite reaction. If an athlete’s arms go faster down and back in the water, they go forward and can go faster and they might win. Their arms come down and back as the action and the reaction is they go forward. When they want to go left or right the action is to kick back to the left and reaction is they turn forward to the right. If they kick down for the action, the reaction is they go forward and the water goes back. When they turn to breathe, the actions and reactions are that they breathe in and out because their heads are out of the water. There are all of the examples for Newton's three laws in marathon swimming.
