Which of of the four forces of flight opposes thrust/propulsion?
Drag
Which of the four forces of flight opposes weight?
Lift
True or False: Air is considered a fluid since it is an invisible gas that flows throughout the air
True
Bernoulli's Principle helps describe which of the four forces of flight
Lift
When a skydiver uses a parachute, he/she is using which type of force: Lift, weight, drag or thrust?
Drag
When air travels faster, does it create higher air pressure or lower air pressure?
Low air pressure
Aerodynamic vehicles prevent: thrust, lift, drag, or weight?
Drag
Which law states that for every action, there's an equal and opposite reaction?
Newton's Third Law
True or False? Gravity pulls all matter to the centre of the earth
True
True or False? Gravity is the biggest restriction to flying and lifting off the ground
True
True or False? Drag cannot be reduced by using aerodynamics
False
True or False? As a plane takes off, its angle of attack gets to 50 degrees
False. 15 degrees
True or False? Birds tuck in their wings to create drag
False. They spread their wings to create drag
How do hot air balloons fly?
The air in the balloon is heated, thus making it less dense than the air outside the balloon. The less dense air makes it float
