Paul Sanders Phys 141 Sect. 16 Newton’s Second Law of Motion Lab- Part I I Goals: The goal of this experiment is to investigate friction of what happens when the normal force acting upon friction is changed. We are also going to experimentally determine the static and kinetic friction coefficients. Theory: The major theory of this lab is Newton’s second law, which states that the force that acts upon an object is equal to that objects’ mass multiplied by its acceleration. In This lab we will expand upon this theory a little more, applying it to friction, which acts upon all objects in contact with each other. Procedure: This lab was split into three major parts. For each part we experimented with two surfaces, wood and felt. The first part involved changing the amount of mass attached to the hook that’s pulling the block to see when the force of friction was overcome. We used this data to find the coefficient of static friction by setting it equal to the weight on the hook and dividing by the normal force. The second part involved changing the angle of the board that the block was
