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.
