How do bird fly ?

What force must birds overcome to take off into the air?

• gravity

• thrust

• lift

• drag

Which part of a bird's body is responsible for generating lift?

• tail

• beak

• wings

• feet

What is the term for the forward force that propels a bird through the air?

• gravity

• thrust

• lift

• drag

How does the size of a bird's body affect its flight?

• • Smaller birds can fly faster due to reduced drag.

• • Larger birds cannot fly as high as smaller birds.

• • Smaller birds require more energy to stay aloft.

• • Larger birds can fly faster but have less ability to maneuver easily

What is drag?

• The force that pulls birds upwards

• • The force that propels birds forward

• • The resistance birds feel as they move through the air

• • The gravitational force acting on birds

What role do a bird's tail feathers play in flight?

• • Generating lift

• • Providing thrust

• Steering and braking

• Increasing drag

What is drag?

• The force that pulls birds upwards

• • The force that propels birds forward

• • The resistance birds feel as they move through the air

• • The gravitational force acting on birds

How do birds achieve lift to rise into the air?

• • By flapping their wings downward, creating higher air pressure above the wings

• By decreasing the air pressure above their wings while moving them

• By keeping their wings completely still

• • By flapping their wings upward, creating higher air pressure below the wings

What is the significance of wing shape in bird flight?

• It affects the bird's speed, maneuverability, and the amount of energy it uses

• It is only important for aesthetic reasons. (how good it looks)

• It has no significant impact on flight.

• It determines the bird's diet.
