Lift
What part of the plane generates lift?
The wings
What is drag?
Air resistance
What produces thrust?
The engines/propeller
What works opposite to gravity?
Lift
What type of air pressure is fast moving air?
Low pressure
Why is drag important for flight?
It allows the plane to land safetly
Which of Newton's Laws of Motion is related to thrust?
The Third-Equal and Opposite reaction
Why is it important to calculate the weight before flight?
The plane could fall out of the air
What side of the wing is low pressure air on?
The top
What are two types of energy we have discussed in class?
Kinetic and Potential
Engines move planes forward by
Pushing back air molecules
Why is weight (gravity) important to flight?
It allows the plane to land and rise safely
What type of wings are most ideal for flight?
Cambered/Asymmetrical
It depends on what you want the plane to do.
How does a parachute slow down an airplane?
more drag
What is Newton's Second Law of Motion and how is it determined (math formula)
Acceleration F=MA
Would the weight of the plane and the mass of it be the same?
No, mass is the the material where as the weight is the force of gravity on the aircraft
Which Newton Law is related to Lift?
The Third- Equal and Opposite Reaction
Why does air help produce drag?
Because it is a "fluid" substance that requires energy to push out of the way, resisting the motion of objects traveling through it
What is necessary for a rocket to achieve thrust?
The force of the thrust must be greater than the weight of the rocket
True or False: Must weight be calculated before flight?
True
