What are, Thrust, Lift, Drag, Weight / Gravity.
100
The very strong shape we used to build kites.
What is a Tetrahedron.
200
The force of attraction that causes things to be pulled toward the centre of the earth.
What is Gravity.
200
The part of the airplane that is responsible for thrust.
What is a Jet engine.
200
The unit used to measure a force.
What is a Newton (N).
200
The stronger two forces acting on a plane during take off.
What are Thrust and Lift.
200
The very strong shape the Romans used to build aqueducts and the coliseum.
What are arches.
300
A raising force.
What is Lift.
300
The name of the man who discovered that the wing of the airplane must be curved to allow for the difference in air pressure that makes lift possible.
Who is Bernoulli.
300
The the of the man who the Newton (N) is named after.
What is Sir. Isaac Newton.
300
The stronger two forces acting on a plane during landing.
What are Drag and Weight / Gravity.
300
The result an earthquake can have on a structure.
What is collapse.
400
Surface resistance, the rubbing of one surface against another surface.
What is Friction.
400
The opposite force to thrust.
What is Drag.
400
This type of force is represented in a diagram with a larger arrow.
What is a Stronger force.
400
A strategy used by engineers when designing planes to make them move more easily through the air.
What is What is Streamlining.
400
Forces must be this in order for a structure to be stable.
What is Balanced.
500
The opposite force to drag. This force moves a structure forward.
What is Thrust.
500
The slower moving air underneath the wing creates this type of air pressure.
What is High pressure.
500
When a structure is moving at a constant speed or not moving at all.
What is Balanced Forces.
500
The two brothers who were first to successfully pilot a plane with an engine.
Who are the Wright Brothers.
500
The forces that work to balance each other and keep a suspension bridge stable.
What are Tension and compression.
