Flight Test Review
Flight test review
| Question | Answer |
|---|---|
| What are the forces that affect flight? | Lift, Drag, Weight/Gravity, and Thrust |
| What is Bernoulli's principle? | Bernoulli's principle states that the faster a fluid moves, the less pressure it would exert. |
| How does Bernoulli's principle affect flight? | Flight is made possible with Bernoulli's principle, as the air flowing on top travels at a greater speed, it exerts less pressure, so it generates lift as the pressure at the bottom on the wing is greater. |
| What are Newton's three laws? | The first law states that objects will stay at a constant state unless a force is acted towards them. Newton's second law states that F=ma. Newton's third law states that for every action, there is and opposite and equal reaction. |
| How do planes fly? | Because of the Bernoulli's principle, the wings generate the lift and the air above have to travel at greater speed. The engines generates thrust because of newton's third law, as the air is pushed backwards, the reaction pushes the plane forward. |
| What is a(n) airfoil/streamlined shape | A(n) airfoil/streamlined shape is a shape that is designed to reduce drag and the body of a jet is shaped this way. |
| How do animals fly? | Some animals glide and birds generate lift and thrust with their wings and legs when they push off of a surface. |
