Adebayo Adesina 106223646 Lab Questions 1. Why is this more accurate? Measuring the height of the ruler and dividing by the number of patterns on the ruler is more accurate that individually measuring the patterns because it reduces the chances of developing errors while measuring each pattern. 2. What can you say about the arrangement of points in each kind of plot? The plot of the displacement vs. time yields a slight curve when a line is connected through each point. The plot of the velocity vs. time is practically a straight line with a slight shift in the middle. The plot of the acceleration vs. time produces scattered points which results in an abstract shape. 3. Could you easily fit a straight line through the data in each of these plots? One can only easily fit a straight line through the displacement vs. time graph. 6. How does this value compare with the textbook value? The textbooks value for gravitation acceleration is 9.80 m/s^2.

Unformatted text preview: The value I obtained from my experiment typical hover very close to this number. The first five tries resulted in the following results, 9.906, 9.796, 9.701, 9.974 and 9.788 (m/s^2). 7. If there is discrepancy, what can be the possible sources for it? One main source of the slight error can stem from an inaccuracy in measuring the exact width of each pattern. 8. What effect does dropping the ruler from a higher elevation have on the acceleration? Dropping the ruler from a higher acceleration has no effect on the acceleration. Gravity is constant. 9. What is the mean time it takes the ruler to fall, according to your data? The mean time in took for the ruler to fall was .19 seconds. 10. What is the standard deviation? 11. What value of g do you get by the method 12. Comment on your results and compare them with those obtained using the photogate....
