Dominic Does the length of the string, weight on the end of the string, or the number of washers on the end of the string effect the number in cycles. We tested all 3 of the tests and the length effected the number of the cycles the most. The length of the string effects the speed of the string. With the angle changed and the number of washers the cycles were the same every time. But when we changed the length of the string the results changed to different numbers. We also made sure the test was fair by keeping the controls the same.

Alex Does the length of the string, weight on the end of the string, or the number of washers on the end of the string effect the number of cycles it takes in 15 seconds? The 3 catagories where tested, and the length of the string was the most effective. The distance the pendulum had to go at 100 cm was so far, and the 10 cm distance was so short. So the distance had to be the same to get same amount of swings.

Dose the length of the string, weight on the end of the string, or the angel of the drop effects a pendulme rang in swings incresas in 15 seconds? as the length of the string incresas, the number of cycels decreasas. so when you have a string that is 10cm and then you have a string that is 100cm which one has the most swingsin 15 seconds? when you have a shorter string that incresas the time it cycels and when you have a longer string that is 100cm decreasas the avrage. when you have a avrage on 10cm,20cm,50cm they are all diffrent,But when you have some numbers like 80cm, 70cm, 60cm, 90cm,100cm,30cm and 40cm are the same pairs. we have a lot of diffrent numbers but some are the same it is so werid.i think the 10cm would be the gratesed avrage so i was right. i know why it was 100cm avrage was the least it is because it was so long and it was a lot slower than it appres to be i know why 10cm avrage was higher because it was smaler and faster than the 100cm was. 100cm and 10cm where diffrent so it was10cm how had the shortest avrage and 1000 avrage was the lest.

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 the string does effect the number of cycles while the number of washers and angle of the drop did not. So the length is the only thing that effects the number of cycles the pendulum takes. When you have a 10 cm string with 1 washer on it you have an average of 17 cycles, but when you have a 100 cm string with 1 washer on it you have an average of 7 cycles. When you have a string with 1 washer on it you have an average of 12 cycles; and when you have a string with 5 washers on it you have an average of 12 cycles. Also when you drop the pendulum from a 90 degree angle you have an average of 11 cycles; and when you drop the pendulum from a 10 degree angle you have an average of 11 cycles. I observed that the angle of the drop does not effect the number of cycles the pendulum takes. I think the reason the 10 cm string had an average of 17 cycles because it had a shorter distance to travel than the 100 cm string did. I believe that the reason why the weight on the end of the string had no efect on the number of cycles the pendulum took was because the length of the string was the same. I feel that, that is the same reason why the angle of the drop had no effect on the the number of cycles the pendulum took. That is my conclusion for swinger's lab!
