Aerodynamics

Drag and Aerodynamics

The shape of an object drastically affects the degree to which air resistance, or drag, impedes the object’s motion. For example, a sphere, top, and especially a square, bottom, both force the air to redirect itself, slowing the objects down. An airfoil, middle, minimally disturbs the air as it travels, so the airfoil experiences little drag.
