AIR AND FLIGHT

Aerodynamics

Shapes of objects to pierce throught the air and move faster.

What Air Is

Air is an invisible gas which we breath in .

Nitrogen 78% Oxygen 21% Other thing 1%

Wright Brothers

The Wright brothers Orville and Wilbur Wright created the first functional airplane.

Newton's Laws Of Motion

Action And Reaction Energy does not change. It is a constant. When one force applied to another, the energy will be equal and opposite

Acceleration is change in velocity.it can mean change in speed or direction. It also means change in velocity over time.

Inertia Inertia means that an object in motion will stay in motion or rest.It will stay in motion unless acted upon.

Four Forces Of Flight

1. LIFT 2. THRUST 3. WIEGHT 4. DRAG

Drag. Makes the plane stay in a straight line.

Wieght. Wieght helps plane to tilt.

Thrust. The force caused by the engine the push the aircraft.

LIFT. The upward force that sustain the plane

Advantages and Disadvantages

Advantages. Disadvantages. Faster tranportation. Dangerous Less traffic

The Properties Of Air

- Air has mass - Air can exert a force - Air changes in altitude - Air can expand - Air takes up space

Part Of An Air Plane

Bernoulli's Principle

Hydrodynamica Air is a fluid but unlike water air is a gaseuos substance Air is considered a fluid because it flows and can take on different shapes. Bernoulli asserted in hydrodynamica that fast-moving fluids make less pressure than slow-moving fluids that make more pressure.
