Macmillan Learning A simple pendulum oscillates between +4.0° (as measured from the vertical) on the surface of Earth. The length of the pendulum is 0.30 m. Define full as the amount of time that the pendulum takes to move from 4.0° to -4.0°, and define thalf as the amount of time that the pendulum takes to move from 2.0° to -2.0° during the same swing. tfull Compare the two times by determining the ratio thalf tfull = thalf

what if instead of timing one oscillation you let the pendulum swing for a total of 10 oscillations then divide that time by 10 oscillations. how do you think this would affect your period measurements?   Physics: what if now instead of 10 oscillations you let the pendulum swing for a total of 1000 oscillations then divided that time by 1000 oscillations. how do you think this would affect your period measurements?

Why is Logger Pro set up to report the time between every other blocking of the Photogate? Why not the time between every block? Using either Graphical Analysis or graph paper, plot a graph of pendulum period vs. amplitude in degrees. Scale each axis from the origin (0,0). Does the period depend on amplitude? Explain. Using either Graphical Analysis or graph paper, plot a graph of pendulum period T vs. lengthl. Scale each axis from the origin (0,0).  Does the period appear to depend on length? Using either Graphical Analysis or graph paper, plot the pendulum period vs. mass. Scale each axis from the origin (0,0). Does the period appear to depend on mass? Do you have enough data to answer conclusively? To examine more carefully how the period T depends on the pendulum length l, create the following two additional graphs of the same data: T 2 vs. l and T vs. l2 . Of the three period-length graphs, which is closest to a direct proportion; that is, which plot is most nearly a straight line…
