Conclusion: After investigating the behavior of a pendulum, I conclude that there is horizontal line relationship between the IV: the time of one swing and the DV: the starting angle of the pendulum. My evidence for this claim is that all my data fits on a best-fit line that is all of my data points over a broad range of angles all line up on a horizontal line. This system of a pendulum swinging can be mathematically modeled as: Time of one swing = 2.3s where the constant (A-value) . Additionally, it makes sense that the pattern is ClickHereToType because ClickHereTo Type. Using this model, I predict ClickHere To Type. Research Extension Question: how does the mass of the pendulum affect the time of 1 swing
