Singapore flight turbulence

If that is the case, how is it possible to throw anything?

I don't see the connection between those 2 sentences.

But to explain throwing - initially the stone is at rest in your hand. You then accelerate your hand to say 10 m/s (the acceleration determined by how far your hand moves, if it's 1 m uniform acceleration it's 50 m/s^2). You release it, and it's then subject to constant downward acceleration g, so it rises for a while, slowing down, stops and falls back down.

it rises for a while

....as does the passenger, stopped by either gravity or the overhead locker.

In bad turbulence the plane's normal aerodynamics go haywire. Normally the plane and it's avionics assume air is consistently dense and moving in a consistent direction and angle. They change but slowly.

In turbulence the air is too churned up and changing too fast for the pilot or avionics to manage. Normally the computer would manage a downdraught by adjusting flaps or angle of attack to provide a bit more lift. But with turbulence the plane is moving through updrafts, downdrafts and crosswinds so fast the automatic controls can't smooth it out.

That means the plane gets pushed up and down, making the passengers bounce around like marbles being shaken in a can.

The passenger only rises from the seat when the plane is falling at > g. The behaviour of a thrown stone has nothing to do with it. But have it your way, I'm out of this discussion.

Wrong.

The behaviour of a thrown stone has nothing to do with it.

It is analogous.

I'm out of this discussion.

As am I.

Sorry, they don't. Lift and objects both fall with acceleration g.

Sorry. You are wrong. They leave their seats and bang their 'eds. As said, the plane goes down AND up.

I was using I as a phrase. Do you read any posts?

If the plane does not go down like a stone (as well as rise), then its' not turbulence.
