Experiment 3 Lab 3 Introduction: The purpose of this memo is to test whether or not surface area has anything to do with the frictional force between two objects. We used a system of wooden blocks and pulleys to determine static friction. With this information and depending upon the block set up we can determine what the frictional force acting upon the objects is. We had two wooden blocks of roughly the same mass and put them on a track. With this we attached them together with a string and put a string around a pulley attached to a mass to determine the force needed to overcome static friction. Results: Maximum surface area: We found out that the mass that was needed to move the block system was 80 grams. With this we can solve the static frictional force which is < (.08 kilograms+.045 kilograms)-mass of weight system- X 9.8 and we find that the force is 1.22 N. We then just stacked the blocks on top of each other. Then we just placed the string around the
