Introduction : In this experiment our group was giving the task of observing how the coefficient of kinetic friction of an object depends upon the mass and the surface area of the object and the effects it had on the acceleration and velocity. Data analysis : The first part of the experiment was to weigh all the masses and make sure we had all the appropriate weights. We then used the block with just its mass and a hanging mass of to find our first values of acceleration. We repeated this technique for the three sides of the block that provided different coefficients of friction. After we ran each side with these masses we doubled the mass of the hanging mass and kept the block mass constant. This gave us our new value of acceleration for each side. After we ran each side with doubled hanging mass and found all the acceleration values, we doubled both the hanging mass and the block mass and found all three values again. This gave us a calculated value for the coefficient of friction that was relatively the same considering any error on our part.

### What students are saying

• 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.
