Ever wondered what makes airplanes fly or what makes a plane stay in the air or how airplanes work? The airplane, which is one of the greatest inventions in transportation, heavily relies on the laws of physics for it to actually work and take you to your desired destination in a lesser amount of time than traveling on land or on the sea.

You may have observed several planes taking off or landing, and the first thing that you’ll have noticed is the engine noise.  You might think that engines responsible for making planes fly, but you’re not entirely correct—to point an example, paper planes and birds can fly without engines, right?. However, a plane’s engine has an important role where it is designed to move it forward at a high speed. Its engine is only one of the things that makes it fly but is not totally responsible for keeping it up in the air. So really, what makes airplanes fly? There are four forces that keep an airplane in the sky—thrust, lift, drag and weight.

Thrust is the force that moves the airplane forward, care of the plane’s engine.

This high speed from the thrust of the plane makes rapid air flow over the wings, which throw the air down toward the ground, generating an upward force called lift that 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. Remember, it’s the engines that move a plane forward, but the wings move it upward.

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. The wings of a plane are curved so that the air moves more quickly over the top of the wing, resulting in an upward push, or lift, on the wing.

Drag slows the airplane.

Airplanes are designed to let air pass around them with less drag. Planes that push a lot of air are said to have a lot of drag or resistance, to moving through the air. For planes to fly as far as possible, it should only have a minimum drag.

The other force that helps keep the plane flying is weight or gravity.

You need to keep your plane’s weight light to help fight against gravity’s pull to the ground. The force that keeps the plane in the sky is the weightwhich is the force that pulls the airplane toward Earth. Airplanes are built so that their weight is spread from front to back which keeps the airplane balanced.

The laws of physics make the plane fly and keep it up in the air, yet, if there is no pilot to operate this machine then it still wouldn’t be able to start flying.
