This simulation gives users an opportunity to investigate the meaning of shape and slope for three types of motion graphs: position vs. time, velocity vs. time, and acceleration vs. time. The simulation opens with a motion diagram of a blue ball moving horizontally, with a position vs. time graph simultaneously displayed. The student's task is to "match" the motion of an adjacent red ball to that of the blue ball, by using sliders to set the initial position, initial velocity, and acceleration. To set it up correctly requires the student to analyze and interpret motion of the blue ball. After matching the motion, students can predict what the velocity and acceleration graphs look like by sliding the end points of the red lines up or down to give correct straight-line graphs.

6-8: 9B/M3. Graphs can show a variety of possible relationships between two variables. As one variable increases uniformly, the other may do one of the following: increase or decrease steadily, increase or decrease faster and faster, get closer and closer to some limiting value, reach some intermediate maximum or minimum, alternately increase and decrease, increase or decrease in steps, or do something different from any of these.
9-12: 9B/H4. Tables, graphs, and symbols are alternative ways of representing data and relationships that can be translated from one to another.
