Wtf, u guys are loll

So i came on this site by a link on my forum.

Why do you think the earth is flat, lol
HAve u ever seen pictures of earth? Or do you think nasa can Photoshop like pro's? Serious wake up. NO gravity? lol how the hell do you think you stay on earth then maybe its a good thing for you guys to fly away to some other planet, plzz do  :?

So explain me why do you think its flat, u guys on drugs or you guys a bunch of Hippies?

I'm sure they have some computer talent at NASA.

NO gravity? lol how the hell do you think you stay on earth

The earth is accelerating at a constant 9.81 m/s^2, which causes the force we feel as 'gravity'.

u guys on drugs or you guys a bunch of Hippies?

No and no.

u addicted to drank then?

Nope.

Wow.

"The earth is accelerating at a constant 9.81 m/s^2, which causes the force we feel as 'gravity'."

That's an acceleration DUE to the force of gravity. The earth is not accelerating at 9.81 m/s/s, or else it would keep going faster and faster for all time. Some engineer.

accelerating at 9.81 m/s/s, or else it would keep going faster and faster for all time.

That's pretty much the definition of acceleration.

You said that THE EARTH

the planet

is accelerating through space at 9.81 m/s/s

That's completely false

An object at the surface will accelerate towards the center of the earth with that value. That is NOT the acceleration of the earth.

...Where is the edge of the Earth?

An object at the surface will accelerate towards the center of the earth with that value.

An object on the surface will feel the force straight down at that value.

Both.

That does nothing to prove that the "earth accelerates at 9.81 m/s/s"

If there is no gravity, the force must come from acceleration.

If there is no gravity, the force must come from acceleration.

What are you talking about

Do you know anything about physics at all?

a) Yes there is gravity

b) forces do not "come" from acceleration

Do you know anything about physics at all?

b) forces do not "come" from acceleration

Apparently you don't.

Accelerations come from forces.

...Where is the edge of the Earth?

What about me.

Also, how would the sun orbit the earth if the suns mass is greater than the earths? Or is the sun flat too.

Hmm, so an accelerating object feels no force?

Look at the top of the page.

Impy, you might want to stop now before you embarass yourself further.

Friendly advice, that's all.

Okay seriously, this is some kind of drug front right?

Wow. I don't think I even need to touch that

"Hmm, so an accelerating object feels no force?"

What are you TALKING ABOUT

I NEVER said that

Um, no.

I'm not sure if impymonk is completely clueless, or just means something different by "force" than TheEngineer does. In a sense he's right. Acceleration does not cause any forces. It creates a "fictitious force", which is not a force but looks the same in practically every way. If the earth is in free fall, but gravity creates a force on every object at the surface of the earth equal to 9.8 m/s^2 times the objects mass, then a ball I drop accelerates towards the earth's surface at 9.8 m/s^2.

If, on the otherhand, there is no such thing as gravity, and the earth is accelerating at 9.8 m/s^2, then if I drop a ball, it feels no force, and therefore (by Newton's laws) remains moving at constant velocity. However, the earth accelerates towards it at 9.8 m/s^2. Since I'm standing on the earth, and have no good frame of reference other than the earth, I can't tell the difference simply by looking at my immediate surroundings. In the reference frame of the accelerating earth (or whatever) we say that it feels a fictitious force - something which is not actually a force, but acts like one because we are looking at things in a non-inertial frame of reference.

So the FEers (at least on this website) have a fairly good understanding of physics, and believe in Newton's laws of motion (just not his laws of gravitation). Some of the REers, by contrast, do not.

Um, no.

I feel like I'm taking crazy pills

That's quite right.

How can the earth accelerate towards it if, as you stated, there is no force. There cannot be acceleration without a force. Your physics fails.

You're basing all of your "physics" on the assumption that the earth is translating in one direction ("up"). According to you, "gravity" is really just the earth moving towards the object (magically, without a force). Gravity is, in fact, an ATTRACTIVE FORCE BETWEEN TWO OBJECTS WITH A MASS.

Once again, your explanation proves nothing. And gravitation does exist, as proven thousands of times with thousands of experiments.

If you can give me an example of a locomotive "entity" that keeps the earth moving through space at your "9.81 m/s/s", I'll never post here again

Otherwise

Science > you guys

I do not know how the (flat) earth could accelerate in the flat-earther's view. Perhaps it is the one exception to the equation F=ma. Perhaps there is some unknown force which is responsible. Perhaps it is perched on four elephants which are in turn riding the giant tortoise A'Tuin. (This last is probably not the majority viewpoint.) I was merely using it as an example to explain the difference between a real force and a fictitious force.

No. According to me gravity exists, Newton was mostly right and Einstein was closer, and I live on a round rock with a 3,875 mile (average) radius that spins once every 23 hours and 56 minutes. Just to clarify, I am not a flat-earther.

That is an important clarification. Once again, however, flat-earth physics don't thoroughly explain their worldview

We can explain the specifics of our universal acceleration force no better than you can explain your universal gravity.

We see the effects of said force - mainly the earth's constant upward acceleration - but beyond that, the details remain elusive. Exactly like gravity in the RE model.

It accelerates by the farts of the giant turtle.
