\nThe correct order of frictional forces from largest to smallest is Static friction > Kinetic friction > Rolling friction.
\n<\/section>\n
\n– **Static friction** is the force that opposes the start of motion between two surfaces in contact. It is generally the maximum friction force.
\n– **Kinetic friction** (or sliding friction) is the force that opposes the relative motion between two surfaces that are already sliding over each other. It is typically less than the maximum static friction.
\n– **Rolling friction** is the force that opposes the rolling motion of a wheel or ball over a surface. It is generally significantly less than kinetic or static friction for comparable loads and surfaces, which is why rolling is much easier than sliding.
\n<\/section>\n
\nThe magnitude of frictional forces depends on the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficients of static, kinetic, and rolling friction usually follow the relationship $\\mu_s > \\mu_k > \\mu_r$. The frictional force is proportional to the normal force ($F_f = \\mu N$).
