Logan Does the length of the string, angle of drop, or weight on the end of the string affect a pendulums range in swings the most in 15 secs? The length of the string affected the range of cycles. The number of cycles decreased as the length of the string increases.

At 10 cm the average is 17 and at 100 cm the average is 7. The difference is 10 swings and takes longer the bigger the length of the string gets. Halfway through it was a difference of 8 and then only dropped about 2. I saw how the way the pendulums affect the longer the string got.

I believe the reason was that as the string got longer the cycles got shorter. It takes longer time to swing back while the front pulls the rest. When you re-tested the experiment showed how that worked. The other experiments that we did failed to show different averages at the of all three tests that we did.

The problem was, does the length of the string, weight on the end of the string, or the angle of the drop affect the pendulum range in swings the most in 15 seconds. I found out that the length of the string has the greatest affect on the pendulum. Also the weight on the end of the string had the smallest impact on the pendulum. A length average for 10 cm is 17 and the average for 100 cm is 7. An average for the number of washers for 3 washers is 12 and for 5 washers it is still 12. An average for the angle of the drop for 90 degrees is 11 and for 10 degrees it is again 11. I noticed that as the length of the string increased, the number of swings in the cycle decreased. I think the length of the string had the most effect because the longer the string, the further the string has to travel in the cycle. Also the shorter the string the shorter distance the string has to travel in the cycle. In conclusion, the length of the string has the greatest impact on the pendulum in this experiment. Hannah 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? In the experiment as the length of the string increases, the number of cycles decreased. The reason that the number of cycles decrease is because when the string is 100 cm., the longer the washer has to go back and forth. The range between the shortest and longest length of the strings was 10 cm. The weight on the end of the string does not change the number of cycles the pendulum does. There is no range for the angle of the drop. An observation that I made was that I had to watch the pendulum very closely so that it will not hit anything because if it does the data will not be accurate. Sean Will the length of the string, weight on the end of the string, or angle of the drop effect the number of swings a pendulum can make in fifteen seconds? Yes, to my surprise, the longer the string is will make the number of swings decrease. But, the weight and angle didnt have much effect.

We started testing with a 10cm length string, averaging 17 swings in three attempts. When we tested a 50cm string, it averaged 9 swings in three attempts, decreasing with the longer length. Finally, we tested a 100cm length string and it averaged 7 swings, making it the lowest number of swings with the longest string. The rate of swings decreased dramatically when the string was longer. The weight on the end of the string did not effect the number of cycles, neither did the angle.

I think the reason the number of swings decreased with a longer string is because the string had a longer distance to travel. I believe the force of gravity pulled more on the longer string, making it go slower. Also, I feel the force of gravity had alot to do with this experiment,
