Use(s) Material is not Suited For: Tutorial or Homework
Limited coverage of topics. The effectiveness only goes so far. The applet lacks practical application and quantitative uses.
General Comments on Effectiveness:
The user cannot evaluate (get an exact quantity for) the displacement or velocity after t = 0, but can only visualize it.
The range of selectable values for velocity and acceleration are limited compared to what could be graphed (given the limits of the displacement graph).
