  • HOW DO KITES FLY? | AKA American Kitefliers Association
    A kite will fly if it finds enough wind to lift it and keep it in the sky Successful kite flight depends upon establishing and maintaining a balance between the upward force of lift, the downward force of gravity, and the backward force of drag
  • The Science Of Flying A Kite » ScienceABC
    In this article, we will introduce you to the science of flying a kite, in the hope that the knowledge of various physical forces involved in kite-flying may give you a head start in acquiring this unique skill
  • How Kites Fly - National Air and Space Museum
    To understand how a kites flies, you need to define what a kite is A kite is a heavier-than-air object that flies… just like an airplane Most kites have three main components: the kite body (which comes in many different shapes and sizes), the bridle (or harness), and the control line (or tether)
  • How to Fly a Kite: Beginner’s Guide from Launch to Landing
    In this article, we’ll show you how to launch and fly both types of kites, plus explain the best kite-flying conditions to look out for and help you choose which type of kite is right for you
  • Kite Launch and Flight - NASA
    Kites come in a wide variety of shapes and sizes, and each kite flies a little differently from another kite On this page we discuss the basics of kite flying with a particular interest in the physics involved in launching and flying the kite
  • How Do Kites Fly? - YouTube
    Kites fly because of the aerodynamic forces of lift and drag The difference in air pressure on the top and bottom of the kite creates lift
  • How to Fly a Kite - Best Ways to Keep a Kite in the Air
    Whether you’re handling a jumbo jet or a kite, aerodynamic forces rule all flying objects To launch a kite into the air, the force of the initial lift must be greater than the kite’s weight
  • Kite - Flight, Design, Dynamics | Britannica
    Three main forces control kite flight: lift, gravity, and drag A kite flies because the lifting force of the wind overcomes both the downward pull of gravity and air resistance to the forward motion of the kite called drag
