Description

This model applies for a point particle subject to a constant acceleration that is either parallel to or antiparallel to the particle's initial velocity. It is a subclass of the One-Dimensional Motion (General) model defined by the constraint da/dt = 0.

  • [velocity (one-dimensional)]
  • [acceleration (one-dimensional)]

    Model Specification

System Schema

Internal Constituents:  None.  Object must be treated as a point particle.
External Agents:  Some constant external influence must be present which produces the acceleration.

Descriptors

Object Variables:  None.
State Variables:  Time (t), position (x) , and velocity (v) are possible state variables.  Note that in some cases only two of the three possible state variables will be needed.
Interaction Variables:  Acceleration (a).

Laws of Interaction

Acceleration must be a constant.
