Phenomenon of Falling

A question directed to FE'ers: If acceleration is acting as a sort the force holding us onto Earth, why when we break that connection (eg. Jumping) do we fall back towards the Earth? It seems as if we would indefinitely drift in a separate plane, above the ground. This cannot (or not rationally) be explained by air resistance in your theory, because by jumping we would go faster upward than the flow of air resistance downward, nothing would force you back to the ground therefore no falling.

Why do you keep asking questions when you know nobody here can't answer, since most likely these questions have been put to the test by children of science!

The earth is accelerating.  When you jump, you increase your velocity relative to the earth.  As the earth accelerates, it catches up to you.

I just answered it.

I mean, you know, with more credability other than an Internet Degree.

Right, but wouldn't you accelerate at the same rate as the Earth? The force of acceleration would have to be applied to all things on Earth, because why would the Sun, moon, and "shadow object" move at the same speed as the Earth?

If the flat Earth is accelerating, then surely the acceleration obviously created by all these people jumping would have forced all matter to be forced into the Earth itself?

Because you know how authority changes things.

Can you rephrase that? That doesn't make any sense to me.

well...not, only "universal" things accelerate, such as celestial bodies. It's a principle called universal acceleration in the FE literature.

So, UA accelerates everything in the universe except things on Earth?  If UA was truly universal and accelerated EVERYTHING, wouldn't the objects on Earth accelerate far ahead of the Earth?  If an equal force is applied to objects with different mass, the object with smaller mass is accelerated more.

Right, but wouldn't you accelerate at the same rate as the Earth?

Only when you are in contact with it.

You stated that the Earth is constantly accelerating, right? Or are you going to change your mind on that one?

If the Earth is constantly accelerating (as in, y'know, all the time since it's creation), then surely the total velocity would be fairly high, which in turn means that all objects on the surface would be forced into the Earth itself, much like when you are forced bac into your chair when you suddenly accelerate on your car, or on a roller coaster.

So why are not all the light things people carry with them on airplanes accelerated to the front?  They are all given the same acceleration, right?

Only when you are in contact with it.

so why doesn't earth smack into planes when they fly?

Yes, it is constantly accelerating.

Well then, I guess it's a good thing we don't feel velocity, only acceleration.

'Upthrust' (yes, the water one) keeps them in the air due to their wings.

Because airplanes create this thing called lift.

From the FE FAQ:

A: No. By the same argument, we could ask why planes/helicopters/paragliders don't crash into the Earth as they accelerate down towards them.  The reason that planes do not crash is that their wings produce an upthrust which, when the rate of acceleration upwards equals that of gravity's pull downwards, causes them to remain at a constant altitude.

Not lift, that's black magic!

So If I jump of a cliff with a hang glider I can fly indefinatly?

Okay, analogy time.  Let's say the airplane is Earth, and the objects are people.  If UA only applied to the airplane and not the objects on the airplane, then the objects would stay in the same place on the airplane, like people on Earth.  They're being accelerated at the same rate as the airplane since there's no other force directly acting on them.  However, if the airplane AND the objects were being accelerated by the same mystery force, the objects would accelerate ahead of the airplane, since they have much less mass but are being affected by the exact same force in the exact same way.

'I don't know, go somewhere else while I try to think of an answer.'

UA means Universal Acceleration right? So everything is accelerating. I am accelerating, you are accelerating and everyone else is accelerating. Why does acceleration only apply while in contact with the Earth, what is forcing the Earth upwards that only works on celestial bodies?

Or did the government attach giant rocket boosters on the back of the Earth, to make the Earth seem more plausibly round.

If you could find an indefinite thermal, yes.  Hang gliders don't create enough lift to completely off set 'gravity', so eventually, you would contact the earth.

Actually, I figured it'd be easier to tell you to read up on a theory that you obviously don't understand very well rather than explaining everything to you. The resources are out there; you don't need to be needy.

Are you saying I don't understand the force that pushes me back into a constantly accelerating object?

Okay, analogy time.  Let's say the airplane is Earth, and the objects are people.  If UA only applied to the airplane and not the objects on the airplane, then the objects would stay in the same place on the airplane, like people on Earth.  They're being accelerated at the same rate as the airplane since there's no other force directly acting on them.  However, if the airplane AND the objects were being accelerated by the same mystery force, the objects would accelerate ahead of the airplane, since they have much less mass but are being affected by the exact same force in the exact same way.

Exactly.

I am saying that, as you said it was due to our high speed.

UA means Universal Acceleration right? So everything is accelerating. I am accelerating, you are accelerating and everyone else is accelerating. Why does acceleration only apply while in contact with the Earth, what is forcing the Earth upwards that only works on celestial bodies?

Or did the government attach giant rocket boosters on the back of the Earth, to make the Earth seem more plausibly round.

It's accelerating the bottom of the Earth, but obviously we aren't coming in contact with the accelerator itself, so we only feel the acceleration while in contact with the Earth due to the fact that the Earth is accelerating and we are not.
