T time for 10 oscillations E t. 2 10 Oscillations ( qua tan ) Step 1: Record the length L of the pendulum from simulation in units of meters Step 2: Find period of oscillation: Start the stopwatch and record time pendulum takes to complete 10 to and fro oscillations, taking care to record this time. Then the period T for one oscillation is just the number recorded divided by 10 using (eq. 2). Step 3: Record data for lengths listed in observation table below.
