Air Pressure in Footballs Essay What is the relationship between feedback from air pressure of a football to the performance of a athlete? Alex Long Purpose The purpose for my experiment is to work out scientifically whether the air pressure inside a football effects the performance of a sports performer. There are several different types and brands of footballs all with different structures and pressure recommended for the ball. It would be interesting to find out the differences between the different companies and whether the air pressure inside makes a big difference in improving performance. Hypothesis My expected results from my experiments to answer the question is that the air pressure which will be best for performance will be around the recommended air pressure but slightly lower as I think that through personal experience to is easier to kick a flatter ball than it is to kick a very hard ball. I think that the most interesting part of the experiment is to see whether different air pressure in different brands of football make a huge amount of difference because the balls could all basically the same with just a logo stuck on the front of the ball. The Experiment Independent- what I am changing: I am changing the air pressure between the experiments and I will be changing the brand of football. Dependent- what I am measuring: The performance of a performer while kicking a ball with different air pressures inside. Controlled- what is staying the same: I will keep the same pump and pressure gauge so that I have the same readings. The air temperature in the room and also the altitude I carry out the experiment. Finally I will also 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 Cones Method 1)Set out 3 challenges for the Athlete to complete 2)The first will be to kick the ball from a cone 12 steps from a football goal and the  have to hit cones either corner of the goal. 3)The second will be a dribbling exercise to test the players control on the ball. 10  cones will be set up in a line each one foot in front of each other and the player  has to slalom through them. 4)The third and final test will test the control of the player. I will through the ball into  the air and get them to control it on their chest and pass in through two cones  which are 2 steps away from each other. The player will stand 10 steps away  from the cones. 5)For each test I will record how many times they complete the task out of 10  attempts. 6)Finally I will repeat this with each ball and at the different air pressures. I will have  a base 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 this  feedback on the balls and the air pressure
