Sliding friction. The force needed to keep one solid surface just sliding over another is known as kinetic or dynamic friction. The force which has to be applied to initiate motion is slightly greater and is called static or limiting friction. The friction increases approximately in proportion to the total perpendicular force(normal reaction) between the surfaces and its ratio to the normal reaction between the surfaces is called a coefficient of friction. 4, record 2, English, - coefficient%20of%20friction

Friction is the resistance force, or drag, that arises when a material surface slips over another surface. Coefficient of friction is a measurement of the slip level between two adjacent film surfaces... The maximum force required to initiate sliding is referred to as the static coefficient of friction. Once sliding has commenced, the minimum force required to maintain slippage is called the kinetic coefficient of friction. 1, record 3, English, - kinetic%20coefficient%20of%20friction

La friction est la résistance qui se produit lorsqu'une surface d'un matériau glisse sur la surface d'un autre. Le coefficient de friction est la mesure du niveau de glissement entre ces deux surfaces. La force initiale pour amorcer le glissement s'appelle le coefficient de friction statique tandis que la force nécessaire pour continuer ce même glissement s'appelle le coefficient de friction cinétique. 1, record 3, French, - coefficient%20de%20friction%20cin%C3%A9tique
