Nathaniel Does the length of the string, 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 string had the most effect on the number of cycles it made in 15 seconds. We used different lengths of string to see if the length effected the amount of swings. The length of the string had the only effect on the amount of swings and the angle dropped from and weight on the end of the string had no effect. On the length of string experiment, the 10cm. test got 17 swings as the average, and on the 100cm. test got 7 swings as the average. On the weight on the end of the string experiment, even when the washers changed from 1-5, the average stayed the same at 12. The angle of drop experiment never changed from 11 on 10 degrees-90 degrees except on the 0 degrees test. I noticed that on the angle of the drop test and weight on the end of the string test that on each test it only got 1 average every time. I think that the length of string had the most effect because the longer the string, the bigger the swing will be, and the smaller the string, the smaller the swing will be. I found out that the angle of the drop does not have any effect for the amount of swings it had. I think that the amount of string had the effect because it was the only test that had different lengths of string. Nasir Does the length of the string, the weight on the end of the string, or the angle of the drop effect a pendulum's range in swings the most in 15 seconds? The answer to this question is as the length of the string increases the number of swings decreases. The length of the string is spoken of in the answer because that's what has the most effect on the range of swings in 15 seconds. There is evidence to prove this conclusion. The test of 'the angle of the drop' used degrees to measure, and at 90 degrees the average number of cycles was 11 while at 10 degrees it was still 11 showing that the angle of the drop has hardly any effect on the range of cycles in 15 seconds. The test of 'the weight on the string' was measured by the number of washers on the string, and at 1 washer there was an average of 12 cycles when at 5 washers there were still 12 cycles proving th weight on the end of the string had no effect either.The test of 'the length of the string' was measured by centimeters, and at 10cm. the average number of cycles was 17 versus the 100 cm. test which could complete only 7 cycles therefore the differences in the length of the string effect the number of cycles in 15 seconds the most. I obsereved that this conclusion and evidence prooved my hypothesis wrong which was that the weight on the string will have the most effect on the cycles in 15 seconds. I believe the reason why the length of the string was the variable to complete the most cycles in 15 seconds is because the smaller the string the less space it must take. If the other pendulums had more than 15 seconds to complete their cycles they would have completed more cycles overall. But, because of the time limit, unrequired angles to reach to complete a cycle, and the small necessary space to cover to complete a cycle it is proven that the length of the string is the variable to complete the most cycles in 15 seconds.

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 swings the most in 15 seconds? Answer: As the length of the string increases, the number of cycles decreases. The shorter the string more cycles it will complete. My evidence on the graph of the test's that we did, of the number of washers that the average cycles it completed 15 seconds were all 12 of the washers had no effect. When we did the angle of drop, the angle had no effect on the cycles because the average is all eleven. But on the length of string the longer it is the less cycles it does. I believe that the longer the string the more time it has to go to complete a cycle because it has to travel further. The shorter the string the less time it has to complete a full cycle. The reason the shorter string does the most cycles in 15 seconds is because it doesn't have to go as far as the longer string.
