  1.  An F18 Hornet sits motionless on a runway because of inertia. If that plane starts to move down the runway, it means that there must be a force acting on it. Of the four main forces that act on aircraft, which one is most likely to cause the forward motion down the runway?

  2. Which of the four forces causes the airplane to become airborne?

  3. Once the F18 Hornet is airborne, which force is trying to hold the airplane back?

  4. If the F18 Hornet was to loose engine power, what force would bring it back to the ground?


  5. As the F18 Hornet travels at a constant velocity, it burns fuel, which decreases its weight. In response to this decrease in weight (or gravitational pull), which of the four forces is also likely to decrease?

  6. Which of the following arrows would indicate the thrust force  of the F18 Hornet pictured above?
         A.      B.      C.      D.

  7. Which of the following arrows would indicate the lift force  of the F18 Hornet pictured above?
         A.      B.      C.      D.

  8. Which of the following arrows would indicate the weight force  of the F18 Hornet pictured above?
         A.      B.      C.      D.

  9. Which of the following arrows would indicate the drag force  of the F18 Hornet pictured above?
         A.      B.      C.      D.

  10. Which one word defines Newton's First Law of Motion?
