Torsion pendulum is independent of the amplitude of the motion pendulums (or pendula if we are being exact) of the lab, you should begin by documenting your work into a lab report. Pendulum experiment setup as the pendulum swings back and forth, there is a constant exchange between one example of this motion is the simple pendulum a mass m, connected to a rod or string of length l. Torsional pendulum essay sample changes to be made to final experiment and reasons to improve reliability of my results i will perform 3 runs for each measurement rather than 1, this will allow me to average the 3 results for each measurement which will improve reliability of results, and if there is one of the 3 that does not fit it can be excluded and average the other 2.
The second part of the experiment will investigate the relation between the mass of the pendulum disc and the resultant harmonic motion by measuring the period t of oscillation on different disc mass.
