Across
  1. 1. The lines on a graph (usually horizontal and vertical).
  2. 3. A line that bends – in distance-time graphs it shows changing speed.
  3. 6. Describes a line that shows no change in distance or speed.
  4. 8. The standard unit of time used in speed calculations.
  5. 13. The "rise over run" of a line on a distance-time graph.
  6. 15. What we measure in seconds, minutes or hours to track motion.
  7. 16. A sharp slope; in graphs, shows faster speed or acceleration.
  8. 17. The slope of a line; in a distance-time graph, it shows speed.
  9. 19. When an object slows down.
  10. 20. A general term for movement.
  11. 21. What happens when speed goes to zero.
  12. 22. In speed-time graphs, the total space under the line shows distance.
Down
  1. 2. How fast something is moving; distance divided by time.
  2. 4. Labels like “seconds” or “metres” that tell us what we’re measuring.
  3. 5. The basic unit of distance in the metric system.
  4. 7. Another word for gradient, or steepness of a line.
  5. 9. How far something travels, measured in metres or kilometres.
  6. 10. How much speed increases every second.
  7. 11. A word describing motion that doesn’t change speed.
  8. 12. Where something is located at a certain time.
  9. 13. A word meaning smooth and unchanging, like constant speed.
  10. 14. A line going left to right; means ‘no movement’ on a distance-time graph. The opposite of vertical.
  11. 18. A longer unit of distance: 1,000 metres.
