Introduction to the Model

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.

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.

S.I.M. Structure of the Model

Compatible Systems

A single point particle (or a system treated as a point particle with position specified by the center of mass).

Relevant Interactions

Some time-varying external influence that is confined to one dimension.
