While performing this experiment, I realized that all of the 8.0 cm results were similar. The 8.0 cm results were 13.3s, 13.2s, and 13.3s which has an average of 13.3s. Based on my research, I found out that T=2π √ (L/g). T is the time that it took for the pendulum to go through 1 period, L is the Length of the string and g is the Acceleration due to gravity which is measured in m/s2
My goal was to see if the weight and length of a string has any effect on its ability to swing. Using my own prior knowledge I came up with the conclusion that both weight and length of a string has an affect on its ability to swing. In order to complete this experiment I would have to build a pendulum using strings and attaching the weights on to the ends of the string. Next, I would use a stopwatch to calculate how many periods it will take the pendulum to sway back and forth. I will do this for each weight. Then, I will shorten the string and use the same weights I used the first time. In the end I realized my hypothesis was partially correct. My results proved that the length of the string has an affect on its ability to swing while the mass of the pendulum shows no affect.
