Procedure 1. Measure the period of the pendulum at the starting length of 0.20m. 2. Increase the length of the pendulum by 0.2m and repeat step 1 seven more times so that the final length of the pendulum is 1.6m. 3. Using the data obtained from steps 1 and 2 , plot the ordered pairs (L,T2) such that L is along the horizontal axis and T2 is along the vertical axis. Do this in Excel, and be sure to include proper axis labels (with units!). 4. Use the computer program Excel to determine the value of the slope of the best-fit line for the data (see attached tutorial). This program forces the y-intercept to be zero, something calculators don't do properly. 5. Use the value of the slope to determine the value of the acceleration due to gravity, g, to three significant figures
