Purpose The purpose of this lab was to measure the motion of falling objects acted upon by the earth’s gravity and air friction. We also measured the time by which it took for the objects to fall when acted upon by air friction. Theory The position of an object falling under the influence of only the force of gravity is given by: s(t) = s o +v o t+(1/2)gt 2 Where s o is the initial position measured in meters, v o if the initial velocity measured in meters per second, and g is the acceleration due to gravity measured in meters per second squared. Gravity is equal to: G = 2∆H/t 2 Where ∆H is the change in height measured in meters and t is the time measured in seconds. Procedure We began the experiment by turning on the computers and the Logger Pro’s. We hooked up two photogates to the Logger Pro and started the experiment by dropping two metal rectangular objects with different masses through the photogates. The photogates measure the time it takes to pass through the first and second one with a distance of 0.5

    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.
