The document is an introduction to an independent research project investigating the relationship between pressure and kinetic energy of a soccer ball. It outlines the background, hypothesis, experimental design, procedures, data collection, results and analysis. The student found that kinetic energy of the soccer ball increases linearly with pressure, following the equation y=0.0669x+1.140, except for one outlier point where too high pressure reduced energy. The experiment could be improved by more securely attaching the pendulum and stabilizing the ball placement. Reasoning and perception were used to analyze whether results matched expectations.
