Airplane forces?

Question

how come when an airplane travels 900mph but you still able to walk freely inside the plane

Answer 1

Most airplanes designed for supersonic speeds are flown by pilots belted into ejection seats, but Concorde has/had rest rooms and an aisle.

The answer is in Newton's Laws of Motion.  As long as the airplane is moving at or near a constant speed, you don't feel the motion, for reasons that are part of the basic principles of the physical universe.

You only get pushed around when the airplane maneuvers or encounters turbulence, which is why the "Fasten Seat Belts" light comes on at those times.

Try it sometime.  You'll like it.

Answer 2

Because you're moving at the same speed as the airplane,  (passenger planes don't go that fast -- that's supersonic.)

Answer 3

Why shouldn't you walk freely INSIDE the airplane?

The airframe shields you from the atmosphere, there is no relative velocity, so no force on you, you walk as if you are in your living room. It would be a different story if you attempted to walk OUTSIDE the airframe.

Answer 4

lol... planes go at 500mph and you are going the same speed as the plane like a car.

Answer 5

The answers above are correct, however I'd just like to add one point:  As the aircraft flies at 500mph, the wind that hits the nose of the airplane doesn't hit you, making it pretty darn easy to maneuver around the cabin.

In one sense or another, we are always moving REALLY fast.  The earth rotates, revolves around the sun, orbits the galactic center, and moves with our galaxy at something like 350,000mph.  The reason we don't detect those movements is because all the things around us that we judge movement by are also moving.
