The standard deviation is the uncertainty for the slope.
Enter the slope its uncertainty in Table 2 in your Activity Log. 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.
