Experiment 4: Resolving & Adding Vectors3/31/2017Student Name:REPORTSection Number:PHYS 1401 - S4LInstructions1)Follow all of the lab activity steps given in the Lab Procedure.2)3)4)Attach additional sheets of paper that clearly (NEATLY) show all of your calculations performed during this experiment.Results1)What is the principle source of error in each of the methods used for vector resolution and addition (graphical, analytical, and experimental)? Which of these methods is most accurate? Why?2)You measured the direction of the analytical resultant relative to the x axis. Would the vector components change if you had used a different reference axis? Would the magnitude of the resultant change? Would its direction change? Explain. Write out your answer in a clear and well supported paragraph.Amna EjazAttach your completeddata tables to this page.
