Speed and Time graphs

  1. 1. A reminder Speed = distance time taken d S x t
  2. 2. Distance vs Time Graphs distance time
  3. 3. No movement? distance time
  4. 4. No movement distance time
  5. 5. Constant speed? distance time
  6. 6. Constant speed distance time
  7. 7. Constant speed distance The slope of this graph gives the speed time
  8. 8. Constant speed distance How would the graph look different for a faster constant speed (walking to Mrs. Herrington’s class)? time
  9. 9. Constant speed fast distance time
  10. 10. Constant speed distance fast How would the graph look different for a slower constant speed (walking to Ms. Jones)? time
  11. 11. Constant speed fast distance slow time
  12. 12. Constant speed distance fast The slope of the graph gives the speed slow time
  13. 13. Constant speed distance Slope = Rise/Run Run time Rise
  14. 14. Getting faster? (accelerating) distance time
  15. 15. Getting faster (accelerating) distance time
  16. 16. Examples distance time
  17. 17. A car accelerating from stop and then hitting a wall distance time
  18. 18. A car accelerating from stop and then hitting a wall distance Let’s try a simulation time
  19. 19. Speed against time graphs speed time
  20. 20. Speed against time graphs speed time
  21. 21. No movement? speed time
  22. 22. No movement speed time
  23. 23. Constant speed? speed time
  24. 24. Constant speed speed time
  25. 25. Constant speed speed How would the graph look different for a faster constant speed? time
  26. 26. Constant speed speed fast time
  27. 27. Constant speed speed How would the graph look different for a slower constant speed? fast time
  28. 28. Constant speed speed fast slow time
  29. 29. Getting faster? (accelerating) speed time
  30. 30. Getting faster? (accelerating) speed Constant acceleration time
  31. 31. Getting faster? (accelerating) speed The slope of this graph gives the acceleration time
  32. 32. Example: speed time
  33. 33. A dog falling from a tall building (no air resistance) speed time
  34. 34. A rock falling from a tall building (no air resistance) speed time
  35. 35. A dog falling from a tall building (no air resistance) speed Area = height of building time
  36. 36. No movement speed distance time time
  37. 37. Constant speed speed Slope = speed distance time Area under graph = distance travelled time
  38. 38. Constant acceleration speed distance time time
