Vehicular Deceleration and Its Relationship to Friction

Vehicular braking transforms kinetic energy principally to thermal energy and results in road tire friction forces which oppose the motion of the vehicle. The relationship between road/tire friction force, vehicular deceleration, and coefficient of friction are discussed. The relationship between road/tire slip and friction are also discussed. In addition, typical results from vehicular brake tests are presented as a basis for showing the relationships between vehicular deceleration and friction.
