Free body and kinetic diagrams of an inclined block

In dynamics a kinetic diagram is a pictorial device used in analyzing mechanics problems when there is determined to be a net force and/or moment acting on a body. They are related to and often used with free body diagrams. Similar to a free body diagram they depict a single body with forces and moments acting on it but in contrast they only include the net force and moment rather than all of the forces being considered.

Kinetic diagrams are not required to solve dynamics problems; their use in teaching dynamics is argued against by some[1] in favor of other methods that they view as simpler. They appear in some dynamics texts[2] but are absent in others.[3]
