Flight Components and Physics

What is the principle behind lift in flight?

• Bernoulli's principle

• Einstein's theory of relativity

• Newton's third law

• Archimedes' principle

Explain Bernoulli's principle and its relation to flight.

• Bernoulli's principle states that as the speed of a fluid (such as air) increases, its pressure increases. This principle is related to flight because it explains how the shape of an airplane wing creates lift.

• Bernoulli's principle states that as the speed of a fluid (such as air) increases, its pressure remains constant. This principle is related to flight because it explains how the shape of an airplane wing creates lift.

• Bernoulli's principle states that as the speed of a fluid (such as air) increases, its pressure increases. This principle is related to flight because it explains how the weight of an airplane affects its lift.

• Bernoulli's principle states that as the speed of a fluid (such as air) increases, its pressure decreases. This principle is related to flight because it explains how the shape of an airplane wing creates lift.

What factors affect the amount of lift generated by an aircraft?

• Pilot's experience, brand of the aircraft, time of day

• Type of fuel used, altitude of the aircraft, length of the runway

• Shape and size of wings, angle of attack, airspeed, air density, lift coefficient

• Weight of the aircraft, color of the aircraft, number of passengers on board

How does drag affect the motion of an aircraft?

• Drag opposes the forward motion of an aircraft.

• Drag causes the aircraft to move sideways.

• Drag has no effect on the motion of an aircraft.

• Drag helps to propel the aircraft forward.

What is air resistance and how does it relate to drag?

• Air resistance is the force that opposes the motion of an object through the air, while drag is a type of air resistance that acts in the opposite direction of the object's motion.

• Air resistance is the force that attracts objects to the ground, while drag is a type of air resistance that acts in the opposite direction of the object's motion.

• Air resistance is the force that propels an object through the air, while drag is a type of air resistance that acts in the same direction as the object's motion.

• Air resistance is the force that causes objects to float in the air, while drag is a type of air resistance that acts in the same direction as the object's motion.

What are the different types of drag experienced by an aircraft?

• thrust drag, lift drag, and form drag

• friction drag, lift drag, and pressure drag

• parasitic drag, induced lift, and vortex drag

• parasite drag, induced drag, and wave drag. This one is the correct answer :)

What is thrust and how does it propel an aircraft forward?

• Thrust is the force that propels an aircraft backward.

• Thrust is the force that propels an aircraft upward.

• Thrust is the force that propels an aircraft sideways.

• Thrust is the force that propels an aircraft forward.

Explain the principle of propulsion in flight.

• Propulsion in flight is achieved by reducing air resistance, creating a forward thrust.

• Propulsion in flight is achieved by flapping wings rapidly, creating a forward thrust.

• Propulsion in flight is achieved by expelling a high-speed jet of gases forward, creating a backward thrust.

• Propulsion in flight is achieved by expelling a high-speed jet of gases backward, creating a forward thrust.

What are the main sources of thrust in aircraft?

• jet engines or propellers

• cockpit

• wings

• landing gear

How does weight affect the flight of an aircraft?

• Weight has no effect on the flight of an aircraft.

• Weight only affects the fuel efficiency of an aircraft.

• Weight increases the maneuverability of an aircraft.

• Weight affects the lift, drag, maneuverability, and fuel efficiency of an aircraft.
