Grayson Does the length of the the string effect the # of cycles a pendulum has in 15 seconds. As the length of string increased the # of cycles decreased. The angle of drop and the # of washers had no effect on the # of cycles in 15 seconds but the length of the string did. The 10 cm. had an average of 17 and the 100 cm. had an average of 7 and the range was 10. The washers had no effect, every average was 12 and the range was 0. The angle of the drop ad no effect either, all the averages were 11 and the range was 0. I think the reason the 10cm. did better than the 100 is that it did not have to travel as much distance. Emily  Our problen for Swinger's Conclusion is, does the lngth of the string, weight on the end of the string, or the angle of the drop in 15 seconds. The answer to to the problem is, as the length of the string increases the number of cycles decrease. We did two other tests numbers of washers, and angle of drop. Both of these tests didn't have any effect in 15 seconds. if we look at the data table, it shows that the 10 cm average of 17 is bigger than 100 cm with an average of 7. now you can see that as the string gets longer, the numbers go down. In number of washers the highest number (average) is 12 and lowest number is 12. Therefor the amount of washers has no effect. In the angle of drop the highest number is 11, and lowest number is 11 and again the angle of drop does not matter. I think that next time we can do the same thing only add longer string. I believe that the reason the length of string is most important is because, If you need a specific length of string you wouldn't want something really long or really short you would want something in between. Terren  problem- does the length of the string, weight on the end of the string, or the angle of the drop effect the number of cycles pendulum takes in 15 seconds.
