Simulation We will first investigate pendulum motion via simulation. Load one of these simulations. Either one is fine. . https://phet . colorado . edu/en/simulation/pendulum-lab (choose "Intro"). . http://physics. bu. edu/~duffy/HTML5/pendulum . html Instructions 1. Record the length L of the pendulum. 2. Use equation 1 above to predict what the period of motion Tored will be. 3. Start the pendulum swinging. Use a stopwatch to measure the time it takes to complete 10 full oscillations (or periods). This gives you the value of 10Tobs. Solve for Tobs. 4. Compare Tobs and Tpred by computing the relative difference % = Tobs - Tpred X 100 Tpred 5. Repeat with a different length, again comparing the predicted and observed periods. 6. Based on your observations, does the simulation accurately reproduce the expected motion of a real pendulum
