Using this link " https://phet.colorado.edu/sims/html/pendulum-lab/latest/pendulum-lab_en.html " and using the intro pendulum lab, fill in Data Table 4.

Procedure (The effect of angle 0 on the period T of oscillation): As mentioned in the theory, the pendulum equation that we want to test is valid only for small angles of 0. For the first measurement, you will test this expectation by finding the period of oscillation at 3 different angles of release: 0=15', # =30", and =80" . For a single length of the string (Z = 50cm), use the timer (not the stopwatch) to measure the period of the pendulum, starting from each of the three different starting angles. Also, remember that the angle 0 is defined as the angle away from the vertical! Record your data in the following data table 3. The theoretical value of the period (T) can be calculated using the following equation. I =2x + - sin 9 + ... 6 Data Table 4: T actual (9) T experimental(S) Percent Error (%%) 150 30 80"
