This document provides information about distance-time graphs and how to interpret them. It explains that a straight line on a distance-time graph indicates constant speed, with a steeper line representing faster speed. A horizontal line represents a stationary object. A curved line shows an object that is accelerating or decelerating. Examples of graphs are provided and questions are asked about calculating speeds from the graphs. Readers are also instructed to draw their own distance-time graphs.

6. Draw a distance-time graph showing your
journey to school!
Try to include different gradients to show
different speeds. Remember – steep slope is
fast, gentle slope slow!!
Try to include rough distances and times at
key points on your graph.
Sketch a distance -time graph for a parachute jump!
Think carefully!!!!

7. Describe the motion of the jogger in each section of the graph!
