[Model Hierarchy]
Description and Assumptions
This model is technically applicable to any point particle system. In practice, however, the vector equations in this model are usually split into three one-dimensional equations, so that the One-Dimensional Motion (General) model is nearly as general, and more easily used.
Problem Cues
This model is rarely needed in introductory mechanics, and is presented principally for intellectual completeness of the hierarchy.
