1/25/16 Drag Force Lab Abstract The purpose of this lab is to understand how drag force affects falling objects with different masses. By using Newton’s second law, we were able to create a net force equation in which Mg - CV T n = 0. From there, we were able to manipulate that equation to help us solve for n and C based on the data we collected. In order to do this experiment, we first found the masses of each coffee filter(s) we were to test. We then used logger pro to create the velocity-time graph in which we were able to find the terminal velocity for each number of coffee filters dropped. We then were able to calculate C using the slope of the linear model of terminal velocity squared and mass. We found C to equal 0.0134 and n to equal 2. Our percent error for the calculation of C was very low with only a 29.1% error, meaning our experimental calculations were very close to the theoretical calculations. In order to reduce errors further, we could make sure there is no air conditioning nearby so the paper coffee filters are not affected as they fall. We could also find a

    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.
