Another interesting mapping to consider any time you use a four forces metaphor is attractionrepulsion symmetry. Label all forces with their agents and make the arrows the correct lengths. In physics, the fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. The most important thing to remember about frictional forces is that they are always parallel to the plane of contact between two surfaces, and opposite to the direction that the object is being pushed or pulled.
