Pendulum Lab

Hypothesis- If we shorten the string, then the pendulum will swing back and forth faster each time.

Methodolgy- Each time we shortened the string we swung the pendulum back and forth three times. We used a timer to calculate the time.

Data- LEANGTH (in)                           TIME (s)

1.         68                                   2.53
2.         64                                   2.52
3.         54                                   2.43
4.         49                                   2.29
5.         43                                   2.13
6.         37                                   1.93
7.         25                                   1.55

Conclusion- Our final conclusion was that when the string is shortended the time decreases from when pendulum is realseased to when it is caught again. Our hypothesis was correct.
