Method

1. Go tohttps://phet.colorado.edu/sims/html/pendulum-lab/latest/pendulum-lab_en.html
2. Select lab
3. Select the stopclock
4. Play the simulation.
5. Set friction to zero.
6. Select a length for the pendulum
7. Displace the pendulum by about 5^o and release it.
8. Now take the time for 10 complete oscillations.
9. Repeat the time measurement.
10. Find the average time
11. Find the average period (average time for one oscillation)
12. Repeat steps 6-11 for eight values of length.
13. Tabulate your results (include a column for T² in your table)
14. Plot a graph of T²vs l.
15. Show the trendline on your graph
16. Include the equation of the line on the graph.
17. Use the equation of the line and equation (2) to determine the value of g obtained from the experiment.
18. How does g given in the simulation compare to that determined experimentally (find percentage error if any)
19. What would cause the values in step 18 to be different?
