    Answers may vary
  • Why is it harder to walk or run through water than through air?
    There is more drag in water
  • To get a car to move forward it needs to have more thrust than _____.
    drag
  • To get a car to move forward it needs more ______ than drag.
    Thrust
  • Explain why one car moves faster than the other.
    The car with the smaller balloon has less drag
  • To get a plane off the ground it needs to have more lift than ____.
    weight
  • What is lift?
    Lift is the push that lets something move up.
  • What is drag?
    Drag is a force that tries to slow something down.
  • What is thrust?
    Thrust is the push that moves something forward. It is the opposite of drag.
  • Can you name one of the four forces of aerodynamics?
    lift, weight, drag and thrust
  • Which car that you raced had less drag?

  • True or False: The larger balloon has more drag.
    True
  • How can you make something move faster using what you know about aerodynamics.
    Have it be smaller or cut through wind better. Shape it like an arrow. Take up less space.
  • For an aircraft to move upward, it must have more _____ than weight.
    lift
  • Can you list all 4 forces of aerodynamics.
    weight, thrust, drag and lift
  • What is aerodynamics?
    It is the way that air moves around us
