7. Procedure Find natural frequency (no damping) by measuring the period several times Turn on damping current Set pendulum in motion and record angle of rotation after each oscillation
16. Procedure Experiment with several driving frequencies in order to find the resonance frequency of the pendulum Record the phase shift between the pendulum and the driving motor Repeat this process over a range of damping currents
21. Damping Constants For driven, damped oscillators, Using this formula, we calculated the damping constant.

24. Conclusion Overall, our data accurately described the typical motion of a torsion pendulum. To improve our results, we suggest being more careful to take many data points around the resonance frequency.
