  • 1. Direction of acceleration due to gravity vectors
  • 2.
    • *
    Acceleration due to gravity is a vector quantity.
  • 3.
    • Vectors can be represented by an arrow to show magnitude and direction
  • 4.
    • On your whiteboards, draw the direction of acceleration for the following objects.
    • The dashed line represents its path.
    • * not drawn to scale
  • 5. #1. A pebble dropped from a bridge
    • *
    Answer
  • 6. #1. A pebble dropped from a bridge
    • *
    The vector is oriented down.
  • 7. #2. A baseball tossed up in the air, halfway up the path
    • *
    Answer
  • 8. #2. A baseball tossed up in the air, halfway up the path
    • *
    The vector is oriented down.
  • 9. #3. A baseball tossed up in the air, at the top
    • *
    Answer
  • 10. #3. A baseball tossed up in the air, at the top
    • *
    The vector is oriented down.
  • 11. #4. A baseball tossed up in the air, right before it strikes the ground
    • *
    Answer
  • 12. #4. A baseball tossed up in the air, right before it strikes the ground
    • *
    The vector is oriented down.
  • 13. #5. A football is thrown at a 45 0 angle, at the top of its path
    • *
    Answer
  • 14. #5. A football is thrown at a 45 0 angle, at the top of its path
    • *
    The vector is oriented down.
  • 15. #6. A cannonball rolling off a table
    • *
    Answer
  • 16. #6. A cannonball rolling off a table
    • *
    The vector is oriented down.
  • 17.
    • What can you summarize about the direction of the vector representing acceleration of all these objects?
    • What are other examples?
  • 18.
    • The rock pebble football and all have different masses. How does this affect the magnitude of the acceleration vectors?
    • On Earth, what would its magnitude be?
