  • 1. Measuring and Describing Motion Page 5
  • 2. How do you know you are moving? 5
  • 3. Motion
    • Change in position relative to reference point
    7
  • 4. Relative Motion
    • Earth moves 30 kilometers every second around sun
      • New York to LA in two minutes.
    7 7 8
  • 5. Distance (Meter) 9
  • 6. Calculating Speed
    • Speed =
    10 Distance Time * All objects have speed
  • 7. Average Speed
    • Average Speed =
    11 Total Distance Total Time 32 km for 2 hours 13 km for 1 hour AS = 45 km/3 hrs = 15 km/hr
  • 8. Instantaneous Speed
    • Speed at a specific point in time
    11
  • 9. 12
  • 10. Describing Velocity
    • Velocity = Speed and direction
    • Vector = Size and direction

  • 11. Graphing Motion 14
  • 12. Different Slopes
    • Segment 1 = 150 m/min
    • Segment 2 = 0 m/min (flat line)
    • Segment 3 = 200 m/min (steeper)
