Front

What happens to the air pressure inside a sealed container when air is sucked out?

Back

The air pressure inside the bottle is less than that outside it.

Front

What occurs to air when it is heated?

Back

It expands and rises.

Front

What is drag in the context of aerodynamics?

Back

The resistance an object encounters as it moves through air.

Front

What is the relationship between air density and altitude?

Back

Air density decreases as altitude increases.

Front

What is the effect of increasing the angle of attack on an aircraft wing?

Back

It can increase lift up to a certain point, after which it may cause stall.

Front

What is the term for the force that opposes the motion of an aircraft through the air?
