  • Dynamics of Flight - NASA
    To roll the plane to the right or left, the ailerons are raised on one wing and lowered on the other The wing with the lowered aileron rises while the wing with the raised aileron drops
  • How planes work | the science of flight - Explain that Stuff
    The low pressure makes air accelerate over the wing, and the curved shape of the wing (and the higher air pressure well above the altered air stream) forces that air into a powerful downwash, also pushing the plane up
  • How Do Planes Fly What Keeps Them In The Air? - Simple Flying
    Although the science behind flight may seem complex, it boils down to the balance of four fundamental forces: lift, weight, thrust, and drag Lift is created by pressure differences above and below a wing, while weight pulls the airplane down due to gravity
  • The Physics of Flight: Why Planes Actually Stay Up
    Airplanes stay up not because of magic, but because of human ingenuity applied to the natural world Lift counteracts gravity, engines provide thrust to overcome drag, and wings and tails ensure stability and control
  • Homepage for How Things Fly
    An Explainer is a trained high school or college student who will answer your questions about how things fly Explainers also host the webisode videos you’ll find throughout this website
  • How do planes fly? - The science that lifts us off the ground | EASA
    At the core of flying there are four main forces: lift, weight, thrust, and drag They essentially act as an invisible team that makes every journey possible Lift pulls the plane upward, weight pulls it downward, thrust propels it forward, and drag resists its motion
  • How do airplanes fly? An aerospace engineer explains the physics of flight
    There are four forces that aerospace engineers consider when designing an airplane: weight, thrust, drag and lift Engineers use these forces to help design the shape of the airplane, the size
  • How Airplanes Fly - Real World Physics Problems
    Airplane engines produce thrust by accelerating the airflow in the rearward direction This backwards acceleration of the airflow exerts a "push" force on the airplane in the opposite direction, by Newton's third law, causing the airplane to move forward
  • Principles of Flight – The 4 Flight Forces Simply Explained
    This speeding up is caused by the wings camber, a fancy aviation term that means ‘curved on top’ A curved line is longer than a straight line, meaning the air must travel further to get to the wing’s trailing edge
  • How Do Airplanes Fly – The Physics Of Airplane Flight
    To fly, they have to generate thrust as well as lift while balancing different gravitational forces How is that achieved? For starters, as that Minute Physics video points out, it isn’t just lift acting on a plane, but drag and gravitational forces which pull it down as well
