Transcript

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