Lab Partner: Lab Section: Date: 01/12/08 Understanding Motion I & II; Measuring the Acceleration of a Freely Falling Picket Fence Abstract: The objective of this experiment was to establish the relationships between the motion of an object and its position on a graph, then understand the motion of an object and a graph of velocity and time for a moving object. Finally we were supposed to measure the acceleration due to gravity of a “picket fence” dropped through a photogate. Our results were very close to the set answers on the graphs we were trying to achieve. In the first experiment, the desired slope should have been .175 m/s, and we achieved .178 m/s +-9.4E-3 m/s, where in the second experiment our ideal acceleration was -.1 m/s 2 and we achieved an acceleration of -.225 m/s 2 exact. Finally, in our last experiment, we were supposed to achieve 9.81 m/s 2 and we achieved an acceleration of 9.7 m/s 2 . Theory: The procedure of this experiments consisted of using a graph on the computer and using a sensor to monitor the position and velocity of the object moving. We tried to match the position

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
