Question

Plot a graph of the pendulum period, T, vs. amplitude, A, in degrees using LabQuest App or graph paper. Scale each axis from the origin (0,0). According to your data, does the period depend on amplitude?

Answer 1

Given the graph of period vs amplitude.

It can be seen from the graph that the plot of the period versus amplitude is almost a horizontal line. That is, as the amplitude increase, the period of the pendulum remains almost unchanged.

This is also consistent with the fact that the period of the simple pendulum indeed does not depend upon its amplitude.

Thus, according to the graph, the period does not depend on the amplitude.
