As seen in the above diagram, when an object is on an inclined plane, gravity is not acting perpendicular to the sliding surfaces. In this case only a portion of the objectâs weight would act as normal force. TRACTION: TRACTION can be defined as the friction between a drive wheel and the surface it moves upon. It is the amount of force a wheel can apply to a surface before it slips.
