Transcript

  • 1.
    • Notes: Speed and Velocity
    • CW: Motion Graphs
    • H: Pinewood Derby
  • 2. Speed and Velocity February 9, 2009
  • 3. Objectives
    • Define distance, time, speed, and velocity
    • Distinguish between and calculate speed and velocity
    • Explain constant speed and average speed
    • Read a distance time graph
  • 4.
    • Motion is measured by time and distance
  • 5. Distance
    • the separation of two positions
  • 6. Distance
    • Commonly measured in
    • meters
    • kilometers
  • 7. Time
    • the period between two events
  • 8. Time
    • Commonly measured in
    • Seconds
    • Minutes
    • Hours
  • 9. Speed
    • the measure of how fast an object moves as it changes its position
  • 10. Speed
    • Commonly measured in
    • Meters per minute (m/m)
    • Kilometers per hour (km/h)
  • 11.
    • Speed = Distance Time
  • 12. Speed Time = 0 seconds meters 25 20 30 15 35 10 5 0
  • 13. Speed Time = 5 seconds meters 25 20 30 15 35 10 5 0
  • 14. Speed Time = 10 seconds meters 25 20 30 15 35 10 5 0
  • 15. Speed Time = 15 seconds meters 25 20 30 15 35 10 5 0
  • 16. Constant Speed
    • speed that does not change
  • 17. Constant Speed
  • 18. Average Speed
    • the total distance traveled divided by the total time of travel
  • 19. Average Speed
  • 20. Speed & Velocity How is speed different from velocity?
  • 21. Velocity
    • describes both the speed and its direction
    • 90 km/h = speed
    • 90 km/h west = velocity
