- 14. Procedure 1. The apparatus was set up as above. 2. The length of pendulum was adjusted 𝑙 = 20.0𝑐𝑚 3. The pendulum was displaced and has been released at the angle of less than 10° from the vertical. 4. The time,t for 20 complete oscillations was measured and was recorded. 5. Step 4 was repeated and the time,𝑡2 was recorded. 6. The average time,𝑡𝑎𝑣𝑒𝑟𝑎𝑔𝑒 was calculated using a formula 𝑡𝑎𝑣𝑒𝑟𝑎𝑔𝑒= (𝑡1−𝑡2) 2 . 7. The period of oscillation, 𝑇 and the value of 𝑇2 was calculated by using 𝑇= 𝑡𝑎𝑣𝑒𝑟𝑎𝑔𝑒 20 . 8. Step 2 to 6 was repeated with the length of pendulum, 𝑙 = 30.0 𝑐𝑚, 40.0 𝑐𝑚, 50.0 𝑐𝑚, 60.0 𝑐𝑚 𝑎𝑛𝑑 70.0 𝑐𝑚 . 1. The data was recorded in the table.
