Experiment 6: The Coefficient of FrictionMaggie HydePartner: Caleb Hern
Results: In this experiment, students measured the coefficients of static and kinetic friction between a wooden block and a wooden plane. Students performed experimental measurements and then used them to get theoretical calculations, which overall, gave them a better understanding of static friction, kinetic friction, and the angle of repose.

Include a diagram of all the forces on the block as it slides down the inclined plane. Shown Attached2.When the mass on the block is was doubled, what happens to the angle of repose? Were your results as expected. Explain.
