Coefficient of kinetic friction中文
WebFor many existing tires, the coefficient of kinetic friction on a dry road surface may approach 0.8 if the braking is not so prolonged as to cause tire melting. The stopping distance is given by: Develop expression If the vehicle speedis v = m/s = ft/s = km/hr = mi/hr and the coefficient of friction between the tires and the road is μ = , WebThe coefficient of friction has different values for static friction and kinetic friction. In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object.
