Forces of Flight
The four forces of flight.
What are LIFT, THRUST, DRAG AND WEIGHT (GRAVITY)?
What is An object at rest stays at rest OR an object in motion will stay in motion unless a force changes it.
The force lift must overcome in order to achieve flight.
What is GRAVITY?
___________ can be compressed and can expand.
What is air?
The force that causes forward movement in a plane using the propellers.
What is THRUST?
Small flaps located on the tail of the plane used to control the plane's up-and-down movement.
What are ELEVATORS?
The name of the force at work in Newton's First Law of motion
What is INERTIA?
When you try to inflate a balloon inside a plastic waterbottle, the balloon will not expand. Which property of air does this demonstrate?
What is AIR TAKES UP SPACE?
The force that allows a kite to fly
What is LIFT?
The special type of wing that is designed to lift things into the air
What is an AIRFOIL?
Newton's Third Law of Motion
What is For every action, there is an equal and opposite reaction
A bird's wing bones are covered with a thin membrane, giving the wing an _______shape.
What is an AIRFOIL?
What are the AILERONS?
What is Bernoulli's Principle?
What is Air that moves faster has a lower pressure than air that moves slower.
What is air that moves faster has a weaker push than air that moves slower
What is air that moves faster exerts a lower pressure than air that moves slower
A bird's tail acts like an airplane's ___________.
What is ELEVATORS?
Hydrodynamica was a book by _________ about how fluids behave in motion.
Who is DANIEL BERNOULLI?
When an object is speeding up through the air, are the forces of thrust and drag balanced or unbalanced?
What is UNBALANCED?
This because when an object is speeding up, thrust overpowers drag. If the object was in the same place, thrust and drag would be balanced. If the object was slowing down, drag would overpower thrust.
The scientist who published the Book "Philosophiae Naturalis Principia Mathematica", also known as Principia
Who is SIR ISAAC NEWTON?
A dandelion's shape allows it to _________ on air currents for thrust.
what is FLOAT?
Are used to help a bird create thrust while in flight.
What are MUSCLES?
