Derive expressions for the static and kinetic coefficients of friction using any terms relevant to the situation (e.g., applied force, normal force, acceleration of gravity, mass, angle of incline). .
Block Pulled on Flat Surface(a) Place a friction block fuzzy side down on a track and add some mass on top to give it extra traction. Pull the block VERY SLOWLY with a spring scale, starting with very little effort but continuously increasing your effort over a few seconds until the block suddenly slips, and then continuing for another second or two with the block sliding at constant speed.
