Rolling Friction Coefficient

Rolling resistance is the force that resists the rolling of a wheel or other circular object along a surface caused by deformations in the object or surface.

The friction force equals the normal force times the rolling friction coefficient.

Formula

QuantityVariable[Subscript["F", "f"], "Force"] == QuantityVariable[Subscript["F", "n"], "Force"]*QuantityVariable[Subscript["μ", "r"], "RollingFrictionCoefficient"]
