1. Tie a string around your object and make at least six marks on the string 10 cm apart. 2. Adjust the length of the string attached to the pendulum to 10 cm and fix the pendulum to any object that will allow the pendulum to hang freely in the air and oscillate back and forth about the equilibrium position. 3. Displace the pendulum through a small angle of 10 degrees and release it. Time 10 oscillations. Practice a few times releasing the pendulum and timing ten complete swings. You may find it easier to ignore the first few oscillations before you start timing. It is important that pendulum only moves in one plane and does not ‘wobble’. 4. Repeat step 3 at least three times (three trials). 5. Repeat steps 1-4 for lengths of 20 cm, 30 cm, 40 cm, 50 cm and 60 cm. 6. For each length calculate the mean (average) time for ONE oscillation. This is called the time PERIOD (T). 7. Draw a labelled diagram of your experiment or take a photo of your experiment settings and paste it in your Lab report. [2] 8. Define the variables for your experiment: independent, dependent and two controlled variables. [4] 9. Draw a table of results for your collected data. Your table of results should include columns for the length (L), t10- time for 10 oscillations for three trials, the mean time for 10 oscillations and the mean period for ONE complete oscillation (T). [7] 10. Plot a graph of T against L. Draw a line of best fit. [5] (You can use Excel to plot your graph or draw the graph on graph paper). 11. Using your graph make a conclusion about the relationship between the period of the pendulum and its length.
