Common examples of contact forces include tension, the normal force, and friction. Contact forces arise due to a large number of long-range forces acting over very small scales.

There are several types, including: applied (from person or machine), tension (from string or cable), gravity (between masses), normal (perpendicular to surface), friction (moving across a surface), thrust (from pushing something the other way), drag (resistance from air or other fluid), buoyancy (from displacing a fluid), and lift (on wings moving through air).

The object is replaced by a square. The individual force vectors are shown as arrows, and magnitudes usually measured in newtons. To determine the net force in the horizontal (x) or vertical (y) direction, add forces pointing in the same direction, and subtract forces in the opposite direction.
