Common Sense
This force caused by friction pushes against an aircraft's forward motion
thrust
lift
drag
weight
This force depends on the mass of the aircraft. The lift force must be stronger in order for the aircraft to gain height.
lift
drag
thrust
weight
This force is generated by the aircraft's engine, causing it to go forward.
lift
drag
thrust
weight
The aircraft's airfoil helps generate this force
lift
thrust
weight
drag
In Bernoulli's Principle, an airfoil generates lift because
the air pressure under the wing is higher because of slower airspeed
the air pressure under the wing is higher because of faster airspeed
the air pressure above the wing is slower because of the lift of the airfoil
the air pressure above the wing is lower because of slower airspeed
The angle at which an airfoil meets the oncoming air is called
Bernoulli's principle
Angle of attack
leading edge
hypotenuse
Which of the following is NOT a factor that influences the amount of lift an airfoil generates?
the aircraft weight
aircraft speed
airfoil thickness
pilot communication system
This creates thrust for an aircraft
aircraft propulsion system
wind resistance
aircraft mass
airfoil
Mechanical energy is
energy of motion
stored energy
electrical energy
useless energy
This says that energy cannot be created or destroyed. It moves from one form to another
Law of Conservation of Energy
a neat suggestion about electricity
Law of Destruction of Energy
Energy motion
Which of the following is NOT a reason to invest in renewable energy resources?
Climate Change
Reducing carbon dioxide emissions
Renewable energy sources will stop working
Nonrenewable sources will eventually run out
How do wind turbines transfer energy?
Mechanical -> Electrical
Electrical -> Mechanical
Mechanical -> Thermal
Mechanical -> Potential
Why should we consider a product's life cycle when purchasing and using items?
To be aware of a product's environmental impact and make good decisions for the environment
so that we can know how long something will last
so that we can throw it away and never worry about it once it's gone
Trick questions: products aren't "living things"
Which of the following is NOT considered a renewable energy resource?
Wind
Solar
Hydropower
Natural Gas
Which of the following is a NON-renewable energy resource?
Wind
Solar
Geothermal
Coal
All of the following are ways that you can apply environmentally friendly practices, EXCEPT...
Conserving water at home
Reducing electricity usage
Throwing everything in the trash when you finish with it
Recycling items when possible
Which is the best description of how electricity is usually generated?
Water is heated and turned into steam, which spins a turbine
Fossil fuels are burned, and that generates electricity
Heat creates electricity
When you plug something into an outlet you have electricity
