Constant Velocity Model 
This is a "first" model built by physics students just to familiarize them
with the icons and functions of the systems modeling tool. The teacher essentially walks the
students through the process of building this model in either Vensim or STELLA.
Distance(t) = Distance(t  dt) + (Rate_of_Change_of_Distance) * dt INIT Distance = 0 Rate_of_Change_of_Distance = 7 Time SpecsStandard: Range 012; dt = 0.25; Integration Method = Euler's
