Michael SprisslerPhysics 1 Lab PHY-128-OL009May 2016FrictionIntroductionThis lab was performed to examine the concept of friction and to calculate the coefficient of friction of an object. We will measure the force required to pull a wooden block with a heavier object (soup can) across various surfaces.Initial ParametersQUESTION 1What is the mass of the system made of the wooden block and the soda can (or the other object that you are using)?
QUESTION 2Convert the mass measured in Question 1 to its weight in Newtons.
Experimental ResultsMass of block: 0.375 Kg Weight 3.75 NTable 1: Wood/Wood (larger surface block)Force StaticFriction (Fs)Force KineticFriction(Fk)Coeff. Static Frictionμs=FsFNCoeff.
