Science behind aviation

Four main forces affect the flight abilities of birds and planes – weight, lift, thrust and drag

We all know that gravity is a force that pulls everything towards the Earth’s surface

Planes and birds have to be able to provide enough lift force to oppose the weight force

To understand the science behind an aircraft’s ability to sustain flight — and the aircraft engineering that takes advantage of that science — you need to start with the engines

They’re not what keeps the plane in the air, though — not by a longshot

The engines are responsible for making the plane travel at high speeds
