Understanding the Forces of Flight

What are the four key forces that allow airplanes to fly?

• Lift, weight, drag, and thrust

• Gravity, friction, lift, and thrust

• Weight, drag, speed, and lift

• Lift, gravity, speed, and thrust

How is lift generated on an airplane's wings?

• By the tail wings stabilizing the airplane

• Through the engines pushing air downwards

• By increasing the weight of the airplane

• By the airfoil shape creating a pressure difference

What is the role of drag in flight?

• To stabilize the airplane in the air

• To increase the airplane's speed

• To resist the airplane's forward motion

• To help the airplane ascend

What is the primary function of thrust in an airplane?

• To generate lift

• To overcome drag and move forward

• To stabilize the airplane

• To increase the airplane's weight

How do engines contribute to an airplane's flight?

• By increasing drag

• By providing thrust to propel the airplane

• By reducing weight

• By generating lift
