If you have ever seen a bird in flight, you know the graceful way they move their wings to stay aloft. While some birds flap their wings rapidly as they fly, others opt for a more energy-efficient gliding technique. So why does Johnny not flap? Let’s take a look at the scientific reasons why some birds choose not to flap.
Lifting Force vs Drag Force:
The first reason why Johnny does not flap is because of the difference between lifting force and drag force. Lifting force is what allows a bird to remain airborne, while drag force is the resistance that it must overcome in order to stay aloft. When Johnny chooses not to flap his wings, he is able to conserve energy by relying on other sources of lift such as thermals or updrafts. This allows him to remain airborne without expending extra energy by flapping his wings.
Air Pressure Differential:
Another reason why Johnny may choose not to flap his wings is due to air pressure differential. Air pressure differential refers to the difference in air pressure between two points in an atmosphere. When there is a difference in air pressure between two points, it creates an area of low pressure which can act as an updraft and provide lift for birds like Johnny who are not expending energy flapping their wings.
So now you know why Johnny chooses not to flap! By taking advantage of the different forces of nature that allow him to remain aloft, he conserves energy and still gets where he needs to go quickly and efficiently. So next time you see a bird soaring through the sky without flapping its wings, remember that it’s just doing what comes naturally—taking advantage of natural forces like thermals and air pressure differentials!
