1 Abstract The purpose of this lab is to better understand friction and its properties. We will be able to attain this goal by using four different experimental techniques to determine the coefficients of static and kinetic friction between a stainless steel track and stainless steel sled. Through the use of graphing our data we will be able to attain a “best-line-fit”, which in this experiment we will use a linear line for our equation. The slope of the equation will yield our final answers for acceleration of the steel sled. This experiment has help me realize even the smallest particle of dust can cause for wacky results when dealing with friction. The experiment was long and tedious but beneficial in the end because now I better understand friction and components that go with it.
