The force that opposes the relative motion of two objects in contact is called
friction. A vector quantity, friction is always parallel to the two surfaces in
contact and acts in the direction that opposes the slipping motion. The
force of friction, F, is directly proportional to the magnitude of the normal
force, Fx. The normal force is the force pressing the two contacting surfaces
together. On a horizontal surface, the normal force is equal in magnitude
and opposite in direction to the weight, F or mg, of the object resting on
the surface. For an object on a surface inclined at an angle 0 to the
horizontal, the normal force is equal in magnitude and opposite in
direction to the component of the object's weight perpendicular to the
inclined surface. That is, on an incline, the magnitude of the normal force
EN is equal to F, cos 6 or mg cos 0. The force of friction, which depends
upon the nature of the two surfaces in contact, is givern by this formula.

The constant, u, is the coefficient of friction, which is the ratio of the
frictional force to the normal force, and thus has no unit.
The formula inmplies that the frictional force is independent of the area in
contact and the speed of motion. For example, a rectangular block of wood,
smooth on all sides, has dimensions 4.0 cm X 6.0 cm x 10. cm, and thus,
