How do planes fly answers

Here are the answers to last Friday’s video, enjoy!

Suggested ICAO level for video: 4+

  1. Lift, gravity, thrust and drag are the primary forces that act on a plane.
  2. When the force of lift created is equal to the force of gravity pulling the plane down, the plane will stay in the air.
  3. It helps it to smash into more air molecules and create lift, which if greater than the force of gravity, help to plane to fly.
  4. The engines overpower the force of drag and move the plane forward.
  5. They’re similar because an engine contains lots of little wings (fan blades) which generate horizontal lift, or more commonly called, thrust.
