Coefficient of friction
The coefficient of friction is the ratio of the frictional force to the force acting perpendicular to the two surfaces in contact. This force is usually gravitational. This coefficient is a measure of the difficulty with which the surface of one material will slide over an other material.
The static or starting coefficient of friction is related to the force required to begin movement of one of the material.
The kinetic or sliding coefficient of friction is related to the force measured during the movement.

Le fait que pour un poids donné, la glace glisse mieux (en statique et en dynamique) ne fait que traduire le fait que les coefficients de frottement sont plus faibles que ceux de l'autre solide.
Il est clair que le coefficient de frottement n'est pas une force.
