Open the simulation (https://phet.colorado.edu/en/simulation/pendulum-lab). Run the simulation and select Intro. Run the simulation and select Intro. Move (drag) the pendulum about 14 degrees away from its equilibrium position and observe the motion. Do not include friction. 18. How does the period T change as you decrease the mass ? 19. How does the period T change as you decrease the length ? 20. How does the period T change as you increase gravity ? 21. How does the period T change if you start over and move the pendulum at about 5 degrees away from its equilibrium position? (you might want to use the Stopwatch and the Slow motion)
