Plot the following graphs: a. Frequency versus Amplitude (Table 1); b. Frequency versus Mass (Table 2); and 0. Frequency versus Length (Table 3). 2. What is the relationship between: a. Amplitude and Frequency? b. Mass and Frequency? \fPart II - Determining Acceleration due to Gravity: THEORY To determine the acceleration due to gravity, we will use a common technique in physics in regards to graphical analysis. Our measured values from the experiment are the period T and the length of the pendulum I. Rewrite Eqn(1) as T=2\" g f And compare to the linear expression ________________________________________________ y=mx+b That is, when you graph T vs. J? , you should get a straight line with: y-intercept of zero; and 2_rr a slope of: J; = m (Eqn 2) So; from ygg data. determine the period T, for each change in length I. Set up your ordered pair as T vs. and graph. Calculate the slope and rearrange [351119) to determine 9. Complete the following Table based on your results: Length Length Frequency Period L Vi f T 100cm=1.00m 10cm=1m 0.47 Hz 2.13 seconds 80cm=0.8m 08.94cm=0.89m 0.55 Hz 1.81 seconds 60cm=0.6m 07.75cm=0.77m 0.54 HZ 1.68 seconds 40cm=0.4m 6.32cm=0.63m 0.76 Hz 1.32 seconds 20cm=0.2m 4.47cm=0.45m 0.99 Hz 1.01 seconds 2. Graph Period versus vLength - ( Tvs VI )3. What is the Slope of your line of best fit.4. 5. Use Eqn 2 and calculate the acceleration due to Gravity constant g' .
