Forces of Flight
The four forces of flight
What is Lift, Weight, Thrust, Drag
This property explains why air can fill up a balloon
What is air takes up space
Object whose free flight does not depend on an engine
What is a glider
What is a hypothesis
This FORCE pulls everything toward the center of the Earth
What is gravity (weight)
Air is made of these elements...
What is Nitrogen, Oxygen, Carbon Dioxide
A physical force presses inward on an object, causing it to become compacted
What is compression
They are famous for inventing the first powered airplane
Who are the Wright brothers
The FORCE generated by the wings
What is lift
True or False: Air has no weight
What is FALSE (air has mass)
Fast moving air = low pressure
Slow moving air = high pressure
What is Bernoulli's Principle
Study of nature, its models, systems, processes, and elements to copy, or take inspiration from, in order to solve human problems
What is Biomimicry?
The FORCE produced by a planes engine
What is Thrust
You can feel this property of air when the wind pushes you
What is air exerts pressure
What is TRUE (Air is less dense above a mountain, while air is more dense at sea level)
This feathery part helps birds steer and balance in flight
What is a tail
This FORCE is caused by friction and differences in air pressure
What is Drag
When you blow into a balloon, it gets bigger. What TWO properties of air are you seeing?
What is air takes up space and exerts pressure
A shaped surface such as an airplane’s wings, tail, propellers, and or blade.
What is Airfoil
Occurs when forces that are placed upon an object are equal in opposing directions
What is net force
