What adaptation helps birds fly?
Some energy source is required to overcome the unavoidable drag of pushing through the air, to lift the bird or airplane up to flying height, and to give the bird or airplane kinetic energy. Airplanes use propellers or jet engines. Birds use strong muscles in their breasts to flap their wings. In addition, bird wings are hinged, while airplane wings are riged and fixed. The bird uses its strong muscles to push its wings downwards, pushing air downwards, generating lift, and, if the wings are angled properly, also thrust. The big problem then becomes not pushing air back upwards when the bird moves its wings up for the return stroke. They have no teeth and hollow bones
Why does a bird flying with outstretched wings seems to glide to the ground while a bird with its wings tucked in tightly nose dives to the ground?
Birds with their wings streched out have more surface area so they catch the air, but birds with their wing tucked into them have no traction and no air catches them.
How do birds use propulsion?
Two main factors help birds fly: their own strength and propulsion. Birds use propulsion by turning their wings, lifting them upward, then turning them downward. As they lift the wings, air pushes up from below and pushes the bird forward.
Why does a birds have wings?
Soft, downy feathers keep birds' bodies toasty and warm. At the same time, the waxy outer ones keep off the rain. More importantly, feathers allow birds to fly. Birds beat their feathered wings to lift off the ground and fly through the air.
How do birds create thrust?
They jump, glide for about a second, and flap their wings in a circular motion. when birds flap it doesn't make them fly it makes them go forward. the bird pushes the air backwards pushing them forwards
Is lift on a plane a push or pull force?
it is a push as the wings 'push' the air downwards
How do birds' wings work?
the birds wings are shaped just right so that air gets under them creating a lower air pressure underneath when they flap. so they fly forward.
How is lift generated in a birds wing?
When in flight, birds flap their wings to push air beneath them. By pushing the air down, they are propelling themselves upwards.
Give an example of newton's second law?
Ex:- Flying gracefully through the air, birds depend on Newton's third law of motion.As the birds push down on the air with their wings, the air pushes their wings up and gives them lift.
Why do sparrows can fly and ostrich cannot fly and what enables the sparrow to fly?
Birds such as sparrows use their wings to push against the air, which enables them to fly.

How do birds flie?
== == Birds fly because their wings are like their fingers and the push off the ground and open their wings and they glide while pushing air out from under them to go higher and to go lower they will just glide and lean foward. == ==
How does a bell helicopter take off?
Pushing Air downwards to fly. Rapidly spinning long, thin blades push air downwards to lift the helicopter up
What are needed to spread out the wings when the birds fly?
Birds use their wing muscles to spread out their wings when they are ready to fly. Birds use thermal air currents, updrafts, and wind to soar and flap their wings when needed.
How birds move?
Birds fly in the air by pushing their chest muscles and moving their wings up and down.
Do animals live in the air?
birds,bats, insects, animals with wings
Does air push up on a kite or a plane?
Yes. Air has power to push and pull on the birds, balloons, kites and planes.
