Our Experiment in Class

Today at Gate class we did an experiment with a pendulum (swinger) and tested the variable of weight (tested how many swings can it go for 15 seconds). Then we added another penny to make it a little heavier. Our standard procedure  was 13 swings when we released the pendulum to 90 degrees, hanging the pendulum on to a pencil, everyones’ pendulum has all the same materials, and when we count a swing, it has to go back to its same position. When we tested the variable of weight, the number of swings did not change. So, The release position and the weight did not change the number of swings in 15 seconds. The very last variable to test is length. Will it change or not?
