Distance-Time Graph

Distance-time graph

• the vertical axis represents distance • the horizontal axis represents time • the gradient of the graph represents speed

Information needed for distance-time graph

(a) Distance-time table (b) Equation that represents the relationship between distance and time

Positive/negative gradient of a distance-time graph

Ways to determine the direction of motion on a distance-time graph

Average speed is used because the speed of a motion usually changes in a journey

Average speed

A straight line

Drawn by joining at least two of the plotted points

Rate of change in distance with respect to time = speed

Speed

A rate which involves distance and time

The relationship between speed and time

Represented by a distance-time graph
