Steven Akdemir Instructor Yan Liu Antonio Nigro, Bassam Hinnawi, Alexander Puchalski Lab 106 March 1, 2016 Static and Kinetic Frictions Introduction: We performed this lab with three main objectives in mind: to measure the static and kinetic frictional forces using a force sensor, to measure the coefficients of static and kinetic friction between surfaces, and to analyze the forces using a free- body diagram and experimentally verify our predictions. Procedure: First, we collected our equipment, which included: a lab computer with Capstone software installed, 850 universal interface, a force sensor, friction apparatus, friction cart, standard set of weights, a string, a bubble level, and a digital scale. For the first part of the experiment, we performed the experiment on a horizontal surface, so the angle was 0 degrees. We began by logging onto the lab computer and opening the “Lab 106 Friction” file in the “Physics 111A Lab Experiments” folder on the desktop. The 850 universal interface was already connected to the computer via USB, so all we needed to do was turn the interface on by connecting it to an electrical outlet and pressing the power button. Next, we plugged the force sensor into the “PASPort 1” input and zeroed the sensor. We then repeated the following six steps while recording the data:

    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.
