The Swinging Pendulum Objective: illustrate the motion of simple pendulum Interim: 1.5 :11 string 6 large washers Stop watch Meter Stick Procedures: 1. Make a pendulum about 1.5 m long using the string tied at the end of the six washers 2. Start the pendulum swing and measure the time it takes for 20 complete cycles. 3. Calculate the time for one cycle 4. Calculate (g) using the equation a= 1-2 5. Repeat using two other lengths. 1.0 m and 0.5 m 6. Calculate the value of {g} 7. Calculate the percentage error of (g) by comparing the average value of 3 experimental to the theoretical value of g which 9.8 III/$2 Essential questions 1. Is the period a'ected if the number of waters was increased to nine or 12 washers? 2. Among the measured [g], which is the most accurate among the lengths used
