Free-body diagram
A free-body diagram shows the external forces acting on one selected object or system. Each arrow names a real interaction, and its direction is the direction of that force. For example, a book resting on a desk has a downward gravitational force and an upward normal force; velocity is not an extra force arrow.

Static friction
Static friction opposes the tendency for relative sliding between surfaces that are not sliding at their contact. In the simple model it adjusts up to a maximum set by the coefficient of static friction and normal force. For example, static friction can push a walking person forward when the foot pushes backward on the ground.
