| Question | Answer |
|---|---|
| What is thrust? | The forward force produced by a planes engine. |
| What is a airfoil? | it is a shape of the wing. The top has lower air pressure, but the air is moving faster. The bottom has higher air pressure, but the air is moving slower. |
| What is drag? | The aerodynamic force that acts against an object moving through the air or another fluid. It also acts in the opposite direction of an object. |
| As the ________ of a moving fluid increases, its pressure decreases. | Speed. |
| The ________ that attracts things toward the centre of large objects. | force. |
| What is Newtons first law? | Things want to keep doing what they are already doing. |
| What is Newtons Second law? | Acceleration of an object depends on the mass of the object and the amount of force applied. |
| What is Newtons third law? | For every action there is an equal and opposite reaction. |
| CanThin air hold up a plane? | yes. |
| A ________ can hold up the plane with out any engines. | Glider. |
| What are the four forces of the plane? | Thrust, lift drag, and gravity. |
| What are the three properties of air? | Air has mass, Air takes up space and Air exerts pressure. |
| what is bernoulli's principle? | As the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. |
| What are the vocabulary of flight? | Flight, Gravity, Force, Drag, Lift, Thrust, Resistance and Glider. |
| What is Resistance? | A force that pushes against something. |
| What is a Glider? | A type of aircraft that flies through the air. |
