lab1

the purpose of  the lab was to gain experience in drawing graphs and using graphing software. we also learned how to use the motion detector to determine the velocity and acceleration of a dropping ball.


the materials we used for this lab:

• graphical analysis software
• lab pro interface
• logger pro software
• motion detector
• rubber ball
• wire basket

Part 1
On this part of the lab we used the software graphical analysis software we where given instructions to open a file where a previous graph with its table and data which had 3 different values in x1,x2,x3 still same graph just different ranges. this information was given to us so we could create our own function and get a graph and create our own values and give it a tittle label the x, and y axis and label units.

The equation we created was F(x)=(x2)^5sin(3x2).

we used this graph to illustrate a heart beat do to its sin waves at each end running from -0.5<x>.05

Part 2

on this section of the lab we set up a motion detector on the floor being covered by a basket we where instructed to drop a ball above the motion detector. which was plugged to the logger pro software to record the fall of the ball.which gave us a graph

the data we collected from this graph gave us how long it took for the ball to hit the ground . the we proceeded to to a curve fit on the graph which then we determined it was a quadratic function which was -7.175t^2+10.56t-2.067
                                                        unit analysis
to find the distance at a certain time you could use the equation d=gt^n where d is the distance (m), g is gravity (m/s^2), and t is time (s). To find what n would be we do the following unit analysis:


                                                       d=gt^n
                                                      m=(m/s^2)s^n
                                                      ms^2=ms^n
                                                      n=2



conclusion
in this lab we got to work together built our team work skills got to used some interesting software the logger pro motion detector  and graphical analysis. with all these programs we where able to create graphs using live data.
