AIR AND FLIGHT
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.
Part Of An Air Plane
The Properties Of Air
- Air has mass
- Air can exert a force
- Air changes in altitude
- Air can expand
- Air takes up space
Advantages and Disadvantages
Advantages. Disadvantages.
Faster tranportation. Dangerous
Less traffic
Four Forces Of Flight
1. LIFT
2. THRUST
3. WIEGHT
4. DRAG
LIFT.
The upward force
that sustain the plane
Thrust.
The force caused by
the engine the push
the aircraft.
Wieght.
Wieght helps plane to
tilt.
Drag.
Makes the plane
stay in a straight
line.
Newton's Laws Of Motion
Inertia
Inertia means that an object in motion will stay in motion or rest.It will stay in motion unless acted upon.
Acceleration
is change in velocity.it can mean change in speed or direction. It also means change in velocity over time.
Action And Reaction
Energy does not change. It is a constant.
When one force applied to another, the energy will be equal and opposite

What Air Is
Nitrogen 78%
Oxygen 21%
Other thing 1%
Air is an invisible gas which
we breath in .
