Does the length of the string, weight on the end if the string, or the angle of the drop affect the pendulums range of swings in 15 seconds? The length of the string did affect the range of swings.However, weight on the end of the string and angle of the drop did not affect the pendulum. The avarge of of the 10cm string was 17 cycles,and the 100 cm string took 7 cycles. The pendulum with one washer took 12 cyces,and the pendulm with 5 washers also took 12 comeplete cycles.when the string was dropped at a 90 degree angle avared at 11 cycles as well as the ten degree drop.So, the length of string had most ﻿affect. I think the reason the length of string had most affect because the 100cm string had a londer distance to travel than the 10cm string.I belive gravity is forceing the string down so the angle of the drop test and the washer test stayed the same. I feel gravity does the same with the length of string but doesnt have much affect.

Nolan Does the length of the string, weight on the end of the string, or the angle of the drop have the most effect on the pendulm's range of swings the most in 15 seconds? The length of string effects the pendulum the most, the larger the string the smaller the amount of cycles there are. We did two other tests, however the﻿y didn't have any major changes in the number of cycles. When we had a 100cm string, the average number of cycles was 7, when we had a 10cm string there was 17 cycles. Therefore, our range was 10 from the highest to the lowest. In the washer test when we put just 1 washer on the string, our average was 12 cycles and when we put 5 washers on the end of the string, our average was also 12. Therefore, there was no change. When the pendulum was at 90 degrese, the average number of cycles was 12, cycles the average number of cycles when it was at 10 degrese was 12 also. So the angle of the drop had no effect on the number of cycles the pendulum takes. I saw that the pendulum takes 12 cycles in 15 seconds. I think the small string did better becaue it had less area to cover. I also think that the longer string did not get as many cycles because of the time and the area it had to cover to make a complete cycle. I think that gravity pulled the same on both strings but didn't make have much affect. Allie

Does the length of the string, weight on the end of the string,or the angle of the drop have the most affect on the pendulums range the most in 15 seconds? We figured out that the length of the string matters on the number of cycles ,and the number of washers and angle of drop do not matter at all. For the number of washers you should have,for all,12 and for the angle of drop you should have the average of 11. for the length of string some are the same some are different but for 10 degrees the average should be 7 and for the 100 degrees the average should be 17.I observed that for the number of washers it was around 12 for the average. I think that this is reasonable because if you did the experiment you could tell that the more string in the air affects gravity.With more gravity it takes more time to get in more cycles, by how long the string is. That is why this experiments solution is that the length of the string makes the difference in the number of cycles.The number of washers only adds weight and has nothing to do with the number of cycles. With the angle of the drop you can determine what angle gets more cycles but when you get the average it is the SAME amount.

Does the length of the string, weight on the end of the string, or the angle of the drop effect a pendulum's range in cycles the most in 15 seconds? As the length of string increases, the number of cycles decreases. In conclusion, the length of the string when increased causes the numbers of cycles to decrease. The data shows that when the number of washers increases the number of cycles decreases. For example, when four washers are used instead of one, two, or three washers the number of cycles decreases. The averages in the data vary. In my observations I noticed that the time keeper told us to stop later then 15 seconds. The length of the string was the variable that caused the pendulum to complete the most cycles in 15 seconds because when the length is shorter it doesn't have to cycle as long a distance. I believe this is the case based on the data. I feel that the results of my data are accurate.
