# Flight test

### A simple test of why flight is awsesome

How does planes fly? Planes use Bernoulli's principle thrust increases where pressures are unbalanced, they gain lift. then they gain more lift and fly
State a principle of air Air has mass, Air has pressure, Air takes up space.
How does the properties of air helps with flight? Air has Pressure takes up space helps most in flight as of the pressure of air is the property generating lift and air takes up space defines the law.
What is the purpose of an airfoil? An airfoil creates uneven pressure between the upper and lower parts of the wing, unbalancing the pressure and generating lift.
How do birds fly? Birds flap their wings , generating thrust and lift, they use a forward and backwards stroke for force and they use their wings to glide.
State newtons three principles in order 1: objects remain in their current motion unless interacted by an outer unbalanced force 2: F=AxS 3: For every action, there is an equal and opposite reaction
Why do some airplanes have larger wings than others? Some airplanes have larger wings than others because they require more lift to operate.
Define motion A type of movement, thrust, a pull, a push, it could be diagonal, forwards, sideways, anything.
vcccc No.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
