For my physics class, we did a lab where we made a pendulum wih varying masses on the end of the string. The distance from equilibrium was 5 cm and then we let the pendulum swing and we timed it for five cycles. What equation would I use to relate the distance from equilibrium, mass, length of pendulum, and time for five cycles to find the period?

EX: Distance from equilibrium:5 cm Time for five cycles: 5.94 s Mass: 100 g Length of pendulum:34.20 cm

The period of swing of a simple gravity pendulum depends on its length, the local strength of gravity, and to a small extent on the maximum angle that the pendulum swings away from vertical, 0, called the amplitude.[8] It is independent of the mass of the bob. If the amplitude is limited to small swings, the period T of a simple pendulum, the time taken for a complete cycle, is
