Specialized Data Collection Modes
Using Motion Detectors
In Distance Match mode, EasyData helps to build understanding of graphs by
letting you try to create data that matches a predefined graph. The sample interval
and number of samples are preset and cannot be changed. Each of the preset
plots is randomly generated so that students have the option of matching a new
plot every time.
In Velocity Match mode, students work to match preset plots of velocity rather
than distance. Interpretation of velocity plots helps to further the understanding of
graphs established during Distance Match. The sample interval and number of
samples are preset and cannot be changed. Each of the preset plots is randomly
generated so that students have the option of matching a new plot every time.
Ball Bounce mode, is a specialized routine to help students understand the
motion of a bouncing ball. When data is collected EasyData adjusts the data, with
respect to the floor, so that each bounce on the distance graph has the same
minimum distance. This helps students to visually connect the data on the graph to
the perceived motion of the ball. The sample interval and number of samples are
preset and cannot be changed.
