Accuracy Of A Soccer Ball Lab Report

Recently I decided to observe how the inflation of a soccer ball influences the accuracy of a soccer ball. In this experiment, I used one Nike soccer ball, one pair of Adidas soccer cleats, a soccer field, an air pump and a pressure gauge. I used a soccer ball with the PSI of 8.7, a soccer ball with 9.5 PSI, and a soccer ball with 7.75 PSI. Changing the PSI of the soccer ball changes the results because the PSI changes the hardness of a ball. I can see how the PSI affects my accuracy by recording the number of attempts it takes to hit the crossbar. I did three trials with each PSI and recorded the data to find out what PSI was the most accurate. This is accurate because I am constantly placing the soccer ball on the same line and kicking it towards the goal. When I overinflated the ball, I averaged 7.7 attempts to hit the crossbar.
One defect was that I was not kicking with the exact same power-accuracy tradeoff each time. This could critically affect my results because my kicks were not constant. Another blemish in my experiment could be the soccer ball or cleats. Not all soccer balls are made of the identical material. That also applies to the soccer cleats as well. This means if anyone was planning to try my experiment their results may be off. Also, not all people are at the same soccer level as me. There are over 200 countries that play soccer, and over 240 million people that play so lots of people have different levels from professionals to beginners. After doing this experiment, I had many questions pertinent to the original question. One question was; How does the type of shoe affect how far you can kick a soccer ball. Another was; How does the material that a soccer ball is built from affect the power you can get behind a ball. This applies to the real world because the differences in accuracy could affect a soccer game. If the ball is not the same PSI, then that could potentially change the outcome of a
