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 sec.I think what happen was that the length of th string effected the experiment the most because of all of the averages were diffrent.I believe that the length of the string was the answer.So I think it is the length of the string.I feel it is length of the string because it was all out of controle.Some answers were probaly not right because it said something way off.The thing i saw was it was atleast 7to18 as the lowest and highest.I believe it was the most complete because the small ones were so small they didn't have to take so long.I feel it was so long because it keeped getting longer and longer.

Swinger's Conclusion. The problem is that the person whop is doing the experiment is trying to see different length and how many cycle it will do in 15 seconds. In the experiment 3 people need to be involved because ther are 3 jobs: timer, pencil holder, and pendulum dropper. During the experiment the pencil holder needs to see if they have the correct angle to drop the pendulum. Then after they have done the experiment 10 times they are now ready to come up with the average and transfer it to the bar graph. We took 10 lengths of string and made pendulums in equal increments of 10 centimeters. We tested every length 3 times each. Then we took the average of the 3 tests and we observed that the short lenghts have more amounds of cycle then the longer lengths. I think the length of the string is the variable because we always used 15 seconds to count the cycles and we also pulled it to the same angle each time. I believe the length of the pendulum determines the number of swings for a give amount of time. I feel a short pendulum will swing more quickly then the longer one.
