Graphical Analysis

                                        FIRST LAB GRAPHICAL ANALYSIS
In this lab the purpose was to gain experience in drawing graphs and in using graphing software. In part 1 we learned how to use the Graphical Analysis software. We learned how to open and use funcion plot graph and how to make a function and graph it . We learned how to add a title to the function and labelthe  x & y axis and how to add units. This is a example of are funcion and the graph that goes with it.

For the part 2

we connected the lab pro to the computer and motion detector to DIG/SONIC2 port to the lab pro. And we opend the mechanics folder and open the graphlab file. And then we practice recording position vs. time graph. After a few trial of dropping the the ball to record the motion we got a nice curve. We then selected the appropriate datar range and performed a fit to the data. It had the general quadratic form of At^2+Bt+C where A=-4.469,B=4.980,C=1.210. Yes in part the acceleration is due to gravity. What is n in the equation

UNIT ANALYSIS: dαg(t)ⁿ

S²m=m/S²(S)ⁿxS²

S²=Sⁿ

N=2
 DIMENSIONAL ANALYSIS:   
dαg(t)ⁿ
[l ]α[l/t^(2)] [t^n]

So n=2 in the equatuion . we finally used dimensional anaysis and unit analysis to verify the equation. Here is a picture of are equation.

Conclusion: we learned how to use the graphical analysis software for the very first time. And selected a function "x2"sin(3^(x)x2") for are graph. We also learned that n=2 in the following equation dαg(t)^(n).
