Homework Statement
So we had to the simple pendulum experiment and were measuring the effect of the length of the pendulum on its period of motion. However, our results produced a line of best fit that was significantly higher than the expected line of best fit (with length vs period squared). This suggests that there's systematic error involved but the error percentage decreases with increasing length. The lengths we used were: 5cm, 10cm, 15cm, 20cm, 25cm, 30cm.
Homework Equations
T=2pi*sqrt(L/g)
The Attempt at a Solution
As we measured the period using PASCO (velocity sensor) and a stopwatch, I don't think there's any significant systematic error associated with the devices as both graphs were similar. But, perhaps there error associated with the length of the pendulum -consistently measuring higher lengths but I don't know how we could've managed that. :(
