Forces of Flight

Creating Lift
Odds and Ends
100
The four forces of flight.
What are LIFT, THRUST, DRAG and GRAVITY (WEIGHT)
100

What happenes when air flows faster on the upper surface (less pressure) than the lower surface of an aerofoil (more pressure).

What is LIFT?
100

It is shaped to allow fast moving air to move on top of it and slower moving air on the bottom.

What is an aerofoil shaped wing?
100
The force lift must overcome in order to achieve flight.
What is GRAVITY?
100

Uses the property that hot air rises to create lift.

What is a HOT-AIR BALLOON?
200
It's the force generated by the wings.
What is LIFT?
200

States that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

What is NEWTON's FIRST LAW.
200

Why is it important for a bird to have strong chest muscles?

What is stronger muscles means that the bird can flap it's wings more often?

200

Shaped to create lift by causing air to move faster above it than below it.

What are WINGS?
200

These are the two main types of propulsion systems used on modern aircraft.

What are JET ENGINES and PROPELLERS?
300
It's the force created by operating a plane's engine(s)
What is THRUST
300

When air flows faster on the upper surface (less pressure) than the lower surface of an airfoil (more pressure), creating lift.

What is BERNOULLI'S PRINCIPLE?
300
Name one difference between the way an airplane flies and a bird flies.
What is FLAPPING WINGS TO CREATE THRUST AND LIFT COMPARED TO ENGINES THAT CREATE THRUST AND WINGS THAT DON'T "NEED" TO MOVE?
300

States that the faster a fluid or gas travels, the lower its pressure.

What is BERNOULLI'S PRINCIPLE?
300
Creates thrust in a spacecraft.
What is a ROCKET?
400
This force is constantly pulling objects downward.
What is GRAVITY?
400

States that acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). 

What is NEWTON'S SECOND LAW?
400
A disadvantage of being able to travel the world in short periods of time (by plane).
What is POLLUTION and/or ACCIDENTS/INJURIES?
400

The type of pressure exerted on an airplanes wings from the slow moving air underneath it.

What is HIGH PRESSURE?
400

Are used to help a bird create thrust while in flight.

(NOT WINGS, THINK ANATOMY)

What are MUSCLES?
500
This force is created as wind (air) passes over the aircraft's surface and creates friction.
What is DRAG?
500

States that for every action there is an equal and opposite re-action.

WHAT IS NEWTON'S THIRD LAW?
500

The tail blade controls the helicopter and propels it in which direction?

What is FORWARDS and BACKWARDS?
500

The type of pressure exerted from faster moving air.

What is LOWER PRESSURE?
500
Water and Air are both examples of these.
What are FLUIDS?
