Experiment 1: Period vs Length
Independent Variable: Length of string
Dependent Variable: Period of one rotation
Constant Variable: Masses( rotating and hanging)
Raw Data:
|Length (m) ϫ = +/-.01m |Time (s)Per 20 Rotations | | |
| |ϫ=+/0.01s | | |
|0.1 | | |5.42 |5.97 |5.29 | |
|0.2 | | |6.73 |7.31 |6.15 | |
|0.3 | | |8.32 |8.32 |8.34 | |
|0.4 | | |9.14 |9.29 |9.36 | |
|0.5 | | |9.92 |9.64 |9.81 | |
