Flashcard For Test Wednesday

Describe Bernoulli's Principle. As the speed of a moving fluid increases, its pressure decreases.
What are the 4 forces? Lift, thrust, drag, and gravity.
Name 1 thing that helps produce thrust. Rockets, jets, or propellers.
What shape of wing does an airplane have? An Airfoil (Streamline) shape.
What acts in an opposite direction to an object's movement? Drag.
Describe Newton's First Law Things want to keep doing what they are already doing (the law of inertia).
Describe Newton's Second Law Acceleration of an object depends on the mass of the object and the amount of force applied.
Describe Newton's Third Law Every action has an equal and opposite reaction.
Explain an Airfoil Shape. The air moving on top has more space to cover so it is forced to move faster than the air on the bottom.
What is Thrust? The forward force produced by the air's engine.
What is Drag? The force that slows down a movement.
How is Weight measured? In Newtons.
How is Mass measured? In Kg.
What is Velocity? Speed.
What are the two main factors affecting drg? Shape and size.
What are the 3 properties of air? Air has mass, air takes up space, and air exerts pressure.
Give an example of Bernoulli's principle. When you are in the shower and turn the water on to high pressure and the shower curtain around your feet gets sucked in.
If there is slower speed, what is the pressure like. Slower speed equals high pressure and vice versa.
