Simple Pendulum Lab - Simulation Based. Show your solutions for the exercises below, including all the equations you used, all the calculations you performed and at least three relevant screen shots. Objective: Use concepts of oscillations in the given pendulum and find out its time period. Material: Use this Phet simulation for Simple Pendulum. https://phet.colorado.edu/sims/html/pendulum-lab/latest/pendulum-lab_en.html Procedure: Part I - Find out time period (T) of Pendulum. 1. When you click to this website, it will take you to this page. + +00 Pendulum Lab Energy Lab Intro PHET : 2. Pick "Intro" from this screen. Then you will see this page. argh Stopwatch Puree Trace MA O Saw O Pendulum Lab PHET : 3. Test each button on this page to understand their functions. 4. Now pick one particular length (L), mass (M) and gravity of Earth, No friction. 5. Use stopwatch to record time of oscillation of the pendulum and pick "Slow" motion onthe screen before you deviate your pendulum. The screen will look like this. +0 03:00 20 O Pendulum Lab PHET : 6. Now deviate pendulum on left side by -33 degrees and the screen will show you that angle. See in the screen shot here. D0-00 ) O Pendulum Lab PHET : 7. Count it as zero and also start your stopwatch at this time. Let the pendulum oscillate. 8. Count 1 when pendulum reaches to the same position where it started. 9. Keep counting for 10 oscillations and record time of 10 oscillations and then stop the stopwatch. See the screen shot here. +0 0 . 00:17 65 Pendulum Lab PHET :1111. The time shown in the stopwatch is the time for 1+1] oscillations here and it is t = 6.1265 s. 11. Now use this time "'t\" to calculate Experimental time period \"T\" using this formula. gm: t.-" 1s. 12. Now calculate theoretical time period of the penduhun using this formula where g = 9.81 m-"s"'2. lib. = 2*Pi'i's'ItL-is) 13. Now fmd out percent error in between these time periods using this equation. {Va error = (TIh-Texp }*1:'lth Part 1] Find out time period ("I") of Pendulum when mass is increased. 14. Now repeat all steps from step 6 -13 with a different mass of the pendulum. Try picking up a heavier mass. 15. You are changing mass only. Rest of the things will stay same as before i.e.. L.ength gravity and friction. 16. How time period of the pendulum with heavier mass {T} is different than time period (T) you found in the Part 1? Part III Find out time period ff\") of Pendulum when length has increased. 1?. Now repeat all steps from step 6 -13 with a longer length of the pendulum. Keep mass same as part I. 13. You are changing length only. Rest of the things will stay same as before i.e.. mass. gravity and ction. 19. 1iWhen you are calculating theoretical time period 1th. use new length of the pendulum there. 26. How time period of the pendulum with longer length {Pi} is different than time period {T} you found in the Part 1? Part IV Find out time period (Tm) of Pendulum when gravity has increased. 21. Now repeat all steps from step 6 -13 with same length. mass and iction as before you had in part I but change gravity om Earth to any other place. 22. You are testing eifect of gravity here. Make sure when you calculate theoretical time period of the pendulum .1131}..- use yoiu' changed gravity. 23. How time period of the pendulum with different gravity (T\"') is different than time period (T) you found in the Part 1'? Part V Find out time period ("1\"\") of Pendulum when angle of deection is changed to lower value of angle. 24. Now repeat all steps from step 6 -13 with same length. mass. friction and gravity as you have used in Part 1. but change the angle of deection to any smaller number than -33 degrees. example is 21:} degrees. 25. You are testing effect of angle that is used to deviate pendulum here. 25. How time period of the pendulum with different gravity (T' ' \") is diEferent than time period (T) you found in the Part 1'? 2?. Now type a full lab report and show you all results, screen shots, calculations, and discussion and conclusion. 23. In discussion and conclusion, show how time period of the pendulum is affected by mass. length, gravity, angle
