Classical and modern views of friction; static friction as a self-adjusting force; limiting friction; kinetic and rolling friction
Laws of static and kinetic friction; coefficients mu_s = f_s(max)/N and mu_k = f_k/N; friction-force graph; friction as a non-conservative force
Motion on a rough inclined plane (up and down); pulling versus pushing a roller
Angle of friction and angle of repose; reducing friction by lubrication, bearings and streamlining
