Introducing the Four Forces of Flight

Let us enumerate each of this for better understanding. The first force, thrust, is the force that moves the airplane forward, of which the plane’s engine is responsible. The high speed from the airplane’s thrust makes rapid air flow over the wings, which throw the air down toward the ground. From this, an upward force is generated, Called lift which is another force of flight. Lift overcomes the plane’s weight and holds it in the sky. Simply put, the lift pushes the airplane up; wings make lift by changing the direction and pressure of the air that crashes into them as the engines shoot them through the sky. The lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down; it is this difference in pressure that enables the plane to fly. Pressure can be reduced on a wing’s surface by making the air move over it more quickly. For additional information, the wings of a plane are shaped like a curve so that the air moves more quickly over the top of the wing, resulting in an upward push on the wing. Remember, it’s the engines that move a plane forward (i.e., thrust), but it’s the wings move it upward (i.e., lift). Another force, called drag, slows the airplane. For a relatable picture, drag is what you feel when you walk against a...
