Document Summary

Frictional force is parallel to the surface and in the opposite direction that the object is sliding. If the body does not slide, the frictional force is a static frictional force ( slides a body along a surface, a frictional force from the surface acts on the body. If the body does not move, the static frictional force, and component of surface are equal in magnitude parallel to the. If the component increases, also increases: the magnitude of has a maximum value ( If the body does slide, the frictional force is a kinetic frictional force : kinetic frictional force is generally smaller than the maximum static frictional force. Greater force normal to the contact plane (normal force on the body) increases the friction, because the surfaces are pressed together and make more contact. When there is relative motion between a fluid (such as air) and a body, the body experiences drag.
