Constant Acceleration Model 
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.
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 SettingsStandard: Range 012, dt = 0.25, Integration Method = Euler's
