Question

A bird flies upwards when it pushes air downward.. Why

Answer 1

Answer:

Explanation:

Songbirds, cranes, and many other species leap up on strong legs while flapping their wings, and there they go. As the airfoil moves to the right, the air above it, going a longer distance, must travel faster than the air below it. This makes the pressure above lower than the pressure below, creating lift.

Answer 2

Action and reaction are always equal and opposite. When the bird pushes down the air with its wings , it pushes the bird upward and it flies.
