Distance – Time Graphs

Graphs are used to communicate quantitative information visually. Most people can understand a graph more quickly and easily than they can a data table of numbers. We can apply this to collecting data for distance and time. By graphing the data collected we can easily calculate other valuable bits of information. Graph the following using the information from the table below. Time (s) Walking distance (m) Running distance (m)

Distance (m) Time (s) walking running

units of speed  the slope of the line in a d-t graph represents speed. Properties of d-t Graphs 1. Direction : positive slope - moving away from reference point negative slope - moving towards reference point

2. Steepness of slope: steep – moving fast shallow – moving slow
