Have you ever wondered how mega-ton airplanes stay airborne? A wonder of science, for sure. But more precisely, it’s a byproduct of Newton’s Laws of Physics. “Airplanes stay in the air because of one simple fact,” says Henry Reich. “There is no net force on them. And with no net force, an object at rest stays at rest and an object in motion stays that way.” Join Reich in this edition of Minute Physics as he explains the phenomenon.
