Pendulum 2

How does a shorter string length affect the average number of strings? We chose the question because we have the materials to test it out. We are further testing the pendulum. 1 washer was 16.375 on average 2 washers was 16.375 on average 3 washers was 16.1875 on average 4 washers was 16 on average Claim: having a shorter string length affected the average swings but mass did not make the swing numbers rise. Evidence: our average of swings stayed consistent. Quiz answer: it would be a bumpy ride. All swings have a straight bar the strings come from and have the same length otherwise it would not be even.
