What is aerodynamics?

Back

The study of the behavior of air as it interacts with solid objects, particularly aircraft.

Front

What is the primary focus of aeronautics?

Back

The science and art of flight through the atmosphere.

Front

What is fluid motion?

Back

The movement of liquid or gas, which is a key concept in aerodynamics.

Back

Oxygen.

Front

How does atmospheric pressure change with altitude?

Back

It decreases with altitude.

Front

What is the composition of the atmosphere?

Back

The atmosphere is primarily composed of nitrogen (78%), oxygen (21%), and trace amounts of other gases.

Front

What is lift in aerodynamics?

Back

The force that directly opposes the weight of an aircraft and holds the aircraft in the air.

Front

What is drag in aerodynamics?

Back

The resistance force that acts opposite to the direction of motion of an object moving through a fluid.

Front

What is thrust?

Back

The force that propels an aircraft forward, generated by engines.

Front

What is the Bernoulli's principle?

Back

An increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.
