Model Specification

System Structure

 

Internal Constituents: Point particle.

Environment: external agents interacting with the particle which are the responsible of the real forces acting on the particle. The total external force must be parallel or anti-parallel to the paticle's initial velocity.

Descriptors

Object Variables: none

State Variables: Time (t), position (x) , and velocity (v).

Interaction Variables: acceleration a.

Laws of Interaction

Any external force which magnitude is not constant. Possible forces are forces that depends on time, on the particle's position or on the particle's velocity.
