Swimming!! Swimming is a very fun sport. I like swimming because you can exercise while having fun at the same time. While you float through the water you are using your hands and feet to move around. Why do you like it? Who invented swimming? It is not really told who invented swimming. Although the date is uncertain there are different texts that refer to swimming. Some of the texts date back to 2500 B.C.E. What is the goal of the game? The goal of swimming is to reach to one side of the pool before your competitor. The lengths (what the different sides are called) are measured in meter such as 25-50-75. How has the game changed over the years? The sport of swimming itself hasn't changed much over the years but the technology to measure speed and distance along with other appliances have been invented. One of the newer technologies built is called the Aquanex. T How has the game changed over the years? The sport of swimming itself hasn't changed but technology to measure speed and distance along with other appliances have been invented. One of the newer technologies built is called the Aquanex. The Aquanex synchronizes underwater swimming and measures the hand force. This also captures underwater swimming video. Another type of technology is called the Torpedo. The Torpedo Expert Software program is designed to track skill change. This is a diagram of a swimming pool. On the picture there are markings showing where the lanes are separated (1-9), there are also indicators in where to do your flip-turn. Lastly there is a marking showing the 25 meter mark. Definitions: Force: A force is a pushing or a pulling factor in motion. Force applies to swimming because you use a specific amount of force when you move your hands and feet. The more force you put in the faster you go. Speed: The rate of measure of the rate of motion (how fast or slow you are going.) Speed is applied in swimming because the only way to win a race is to go faster then your component. Thus showing your speed is faster. Gravity: The natural force of attraction exerted by a celestial body, such as Earth upon objects at or near its surface. Gravity is a force that attracts things with mass. Gravity is used in swimming because when you swim the water is pushing down on you. That shows gravity. Velocity Speed in a distance. Velocity is a part of swimming because as explained in the speed definition you swim at a fast speed to win. You also need to know what direction you go in so you do not bump into the wall. Acceleration: How quickly you can change speed over time. Acceleration is a great part of swimming because you need to test your stamina. A way to do that is by checking your speed at different times of the swim. Friction The resistance that one surface or object encounters when moving another. You use friction while you swim because your body is rubbing against the water. That causes you to slow down. This is called fluid friction. The friction here is wanted because even though the fluid friction makes you slower it is still keeping you on the water. Without it you would just float into air. Work: The amount of energy transferred by a force acting through a distance. Work relates to friction because when you swim you calculate your distance. The longer the distance the more work. Simple Machine: Is a device used for making work easier. The different types are: pulley,gear,wheel and axle,wedge,inclined plane,lever and screw. Simple machines such as levers are used in swimming. A first class lever is used in swimming because a first class lever is a lever that changes direction of the input force. Your arm muscles provide force and the swimmers shoulder is the fulcrum. The water is the resistant. Another simple machine used is the wedge. A wedge is used to split things apart. Your hand is acting as a wedge as it splits the water (in freestyle). Power: Power: How much work is done in a certain amount of time. This applies to swimming because one way to see who won the race is to calculate how much work has been completed in the timed amount. Average Speed... Two Things... Two things that must be measured to determine the average speed of swimming is 1. distance and 2.time.

A Way? A way to find out the average speed is by taking the distance (which can be easily found, every side is of the pool is 25 meters) and dividing it by the time (that can be found by using a stopwatch). Then do it a couple more times. Add all of your results and divide by the number of times you did it. This speed is controlled by the athlete because the speed of swimming is depended on how the athlete kicks. That was a picture of what a distance time graph might look like. The distance is the number of meters. The time is the minutes it takes. This swimmer

the water like a wedge.
