Airplane

: The downward pull of gravity that pilots must constantly counteract with lift.

The magic of flight is actually a delicate balance of four physical forces: airplane

The Physics of Freedom: Why We Are Obsessed with the Airplane : The downward pull of gravity that pilots

: The air resistance that tries to slow the plane down, minimized by sleek, aerodynamic designs. minimized by sleek

We’ve come a long way from the sands of North Carolina. Here are the pivots that changed everything:

: Produced by powerful jet engines or propellers to move the plane forward.

: Generated by the airfoil shape of the wings. Air moves faster over the curved top, creating lower pressure (Bernoulli's Principle) that pulls the wing upward.
