Air Pressure in Footballs EssayWhat is the relationship between feedback from air pressure of a football to the death penalty of a athlete?Alex LongPurposeThe purpose for my experiment is to work away scientifically whether the air pressureinside a football effects the performance of a sports performer. at that place are several divers(prenominal) types and brands of footballs all with distinct structures and pressurerecommended for the ball. It would be interesting to find come out of the closet the deviances betweenthe different companies and whether the air pressure inside makes a big difference in modify performance.HypothesisMy expected results from my experiments to answer the question is that the air pressurewhich go out be best for performance ordain be around the recommended air pressure butslightly lower as I think that through personal experience to is easier tokick a flatter ballthan it is to kick a very hard ball. I think that the most interesting part of the ex periment isto see whether different air pressure in different brands of football make a huge amountof difference because the balls could all basically the identical with just a logo stuck on thefront of the ball.The ExperimentIndependent- what I am changingI am changing the air pressure between the experiments and I testament be changing thebrand of football.Dependent- what I am measuringThe performance of a performer age kicking a ball with different air pressures inside.Controlled- what is staying the sameI volition alimentation the same pump and pressure gauge so that I have the same readings. Theair temperature in the direction and also the altitude I carry out the experiment. Finally I leave alonealso keep the same athlete to under take every exercise.Material and Apparatus 1x Sports Hall 3 different types of footballs 1x Pump with a pressure gauge 1x Athlete 1x Thermometer 1x Football goals 1x Stopwatch 25 ConesMethod1)Set out 3 challenges for the Athlete to complete2)T he first will be to kick the ball from a chamfer 12 steps from a football goal and thehave to hit cones either corner of the goal.3)The foster will be a dribbling exercise to test the players control on the ball. 10cones will be set up in a line to each one one foot in front of each other and the playerhas to slalom through them.4)The third and final test will test the control of the player. I will through the ball intothe air and get them to control it on their chest and pass in through two coneswhich are 2 steps away from each other. The player will stand 10 steps awayfrom the cones.5)For each test I will record how many times they complete the task out of 10attempts.6)Finally I will repeating this with each ball and at the different air pressures. I will havea subject test at the recommend psi the ball manufacture gives.7)After this all completed I will ask the athlete which he felt was better to get thisfeedback on the balls and the air pressure
