{excerpt:hidden=true}{*}System:* One [point particle] constrained to move in one dimension. --- *Interactions:* Any that respect the one-dimensional motion. {excerpt}
h4. Introduction to the Model
h5. Description and Assumptions
This [model] is applicable to a single [point particle] subject to an [acceleration] that is constrained to one dimension and which is either parallel to or [anti-parallel] to the particle's initial [velocity].
h5. Learning Objectives
Students will be assumed to understand this model who can:
* Choose the one graph possible velocity or acceleration vs. time graphs which corresponds to a model position versus time graph.
* Differentiate position given as a polynomial function of time to find the corresponding [velocity] and [acceleration].
* Integrate the velocity or acceleration when given as a polynomial function of time along with appropriate initial conditions to find the functional form of the position.

h5. Compatible Systems
A single [point particle|point particle] (or a system treated as a point particle with position specified by the center of mass).
h5. Relevant Interactions
Some time-varying external influence that is confined to one dimension.
