| friction |
Friction is a force that resists the motion of an object. Friction results from the close interaction between two surfaces that are sliding across each other. When you slam on your brakes and your car skids to a stop with locked wheels, it is the force of friction that brings it to a stop. Friction resists the car's motion.

| friction |
The force produced as reaction to movement. All fluids are subject to friction when they are in motion. The higher the fluid viscosity, the higher the friction force for the same flow rate. Friction is produced internally as one layer of fluid moves with respect to another and also at the fluid wall interface.

| friction |
Surface interaction phenomena of two bodies in the contact area which gives rise to a reciprocal sliding friction, known as friction force. This force peaks at the beginning of sliding (breakaway friction) and generally decreases as the sliding speed increases.

| friction |
A disturbance which appears either on the high-points of a coin or in the fields, as a result of that coin rubbing against other objects. A coin is said to have friction when only the lustre is disturbed, and no actual wear of the metal is visible to the naked eye. Many strictly uncirculated coins can have some friction, often from storage in old style coin cabinets or albums or from rubbing against other coins in rolls. (See "Rubbing").
