After building the constant velocity model under teacher direction, the students then try to expand the model to include constant acceleration. This requires input from the teacher, but students are allowed to experiment at first. The model below may be built in Vensim or STELLA. THE MODEL Vensim Version Vensim PLE Software Right-click to download the model Simple Acceleration Vensim STELLA Version isee Player Software Right-click to download the model Simple Acceleration STELLA PC Simple Acceleration STELLA Mac [Diagram Level | Equations Level | Graphs ] Distance(t) = Distance(t - dt) + (rate_of_change_of_distance) * dt INIT Distance = 0 rate_of_change_of_distance = Velocity Velocity(t) = Velocity(t - dt) + (rate_of_change_of_velocity) * dt INIT Velocity = 0 rate_of_change_of_velocity = Acceleration Acceleration = 3 Time Specs Settings Standard: Range 0-12, dt = 0.25, Integration Method = Euler's
