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 
, and velocity (v).
Interaction Variables: acceleration a.
Laws of Interaction
Possible foces:
A force that depends on time
$ \vec
(t) $
A force that depend on the particle's position
$ \vec
$
A force that depend on the particle's velocity
$\vec
(v) $
Laws of Change
Example:
\begin
$v_
= v_
+ a (t_
- t_
)$\end
