Does the length of the string, weight on the end of the string, or angle of the drop effect a pendulums range in swings the most in 15 seconds?the answer to the problem is the length of the string effects the number of swings. The number of swings on the 100cm is 7.On the length of the string the average for the 10cm is...17, and the average for the 100cm is...7.On the number of washers the average for 1 washer is...12 and for 5 washers is 12.on the angle of the drop the average for 90o is 11. I observd that the 10cm had more swings than every othe swings. I think that the 10cm had a shorter dis ance to go.The reason why is because the obervtaions was that when you added 10cm it swing fewer times. the results show when it's 10cm it swing on average 17 times and on 100cm it swing on average 7 times. The numberof washers and angle of the drop has no effect of the average.

We were trying to find out if the length of the string, angle of the drop, or number of washers on the end of the string effected the number effected the number of cycles the pendulum made. The length of the string effected the number of cycles the washer took. The longer the string the less cycles it took and the shorter the string got the more cycles it took. The angle of the drop and the number of washers on the end of the string did not effect the number of cycles the washer took. The test of the length of the string's range was ten. The range of the angle of the drop was twelve and the range for the number of washers was eleven. All the average numbers for all the angle of the drop test and number of washers test were the same. The angle of the drop was eleven cycles and the number of washers was twelve cycles. I believe that the length of the string effected the number cycles the washer took because of the time it took to complete one cycle.So the longer the string is the more time it takes to complete one cycle.If it is shorter it takes less time to complete a cycle. So if you do the shortest string it will take less time to make a cycle. But if you use the longest string it will take more time to complete a cycle.
