Physics 1020 Experiment 3 Part IV: Data Analysis The velocity of a falling object is given by v = -gt + vo. The equation of a straight line graph is y = mx + b. Compare these equations and answer the following. QUESTION 12: What is the value of g and its uncertainty from the velocity versus time graph? Physics 1020 Experiment 3 Part IV: Data Analysis Click on your acceleration vs time graph to active it. Highlight the region of constant acceleration between t1 and t2. Click Analyze then Statistics. Edit the title to “Acceleration vs.Time” Enter the mean, standard deviation, point count, and standard error in Table 3 in your Activity Log. QUESTION 13: What is the value of g and its uncertainty from the acceleration versus time graph? Print your graph and include it with your lab report. Physics 1020 Experiment 3 Part V: Summary QUESTION 14: Are the three values of g, determined in Part IV equal to each other within the uncertainties? Are they equal to the accepted value of 9.81 m/s2? Comment on any differences. QUESTION 15: List at least 3 uncertainties in this experiment. Classify them as random or systematic. Justify the classification. Physics 1020 Experiment 3 Part V: Summary Make sure you have answered all Questions completely. Check that you have completed all Tables in your Activity Log. Include your printed graph from LoggerPro....
