Notes - Net Forces and Applications of Newton`s Laws
... Free-body diagrams represent forces (their magnitudes and their directions). In a freebody diagram, all forces are represented using arrows. The direction of motion is considered positive (usually assigned the right direction); the direction opposite the motion is negative (typically assigned the le ...
