Does the length of the string, weight on the end of the string, or the angle of the drop effect pendulums range in swings the most in 15 seconds? The length of the string had the most impact on the most cycles in 15 seconds. In the end, the angle and the weight did not do anything to impact the number of cycles in 15 seconds. The average number of cycles in 15 seconds for the number of washers was 12 for 1-5 washers tested. The average number of cycles for the angle of the drop was 11 from 10 degrees to 90 degrees tested. The average range for the length of the string tested was 17 cycles for 10 cm and 7 cycles for 100 cm. From what I have observed the shorter the string the more cycles occurred. I think that the only variable that has an effect on the number of cycles is the length of the string. I believe the reason the angle did not make an impact was because the pendulum had to travel more distance per cycle. I feel that the weight of the washers had the same impact as increasing the angle; it just caused the pendulum to go farther per cycle.

Does the length of the string, weight on the end of the string, or the angle of the drop effect a pendulms range in swings the most in 15 seconds?

The length of the string, effected the pendulums range in swings the most in 15 seconds. On the data, the avrage number of swings was always 12 when we added more washers. The average number of swings which was always around 11 swings, did not change when we changed the angle of the drop. The length of string made the most difference in the number of swings with the 10 cm string swinging 17 times. In my group, we had to add more washers with each test and this did not change the number of swings by much. I think the angle of the string or wieght does not effect the number of swings. I believe that only the length of string changes the dependent variables. The reason for this is the longer the string the longer time it takes to travel and the further distance it had to travel.

Does the length of the string, the weight on the end of the string, or the angle of the drop effect a pendulums range in swings the most in 15 seconds? The length of the string had the most effect in this experiment. The 10 centimeter string went back and forth so many times because it was short and it didn’t have to travel far. The 100 centimeter string was long, so it had a long distance to travel, meaning it didn’t go back and forth as much. The other parts of this experiment like the weight on the end of the string and the angle of the drop didn’t have a different between the data. Like I mention before, the 10 centimeter string was short. It went back and forth 17 times. The 100 centimeter string did 7 cycles. The length in the middle, 50 centimeter string, did it’s cycles 9 times. I noticed that the longer the string got, the less the string went back and forth. I think the reason the length of the string had the most effect was because there was actually a difference between the data. Unlike the other parts of this experiment. I can conclude that length of the string is the most important independent variable in this experiment and probably in a lot of other experiments similar to this one.
