At any given point, if you jump perfectly straight in the air, the earth will move with out you and you will stand in a different spot than before you jumped, amirite?

well you have the same momentum as the earth, so when you jump in the air, you are moving at the same speed as the earth, so you should land in the same place

Not if you do it right.

#### In response to “Not if you do it right.”

I just dont think its accurate. you must keep the same speed as the earth when you jump, you dont just stop in midair, otherwise it would seem as if you went flying off the earth at a ridiculous speed

#### In response to “I just dont think its accurate. you must keep...”

I meant the movement of the tectonic plates...

I said earth meaning ground not Earth meaning the planet.

#### In response to “I meant the movement of the tectonic...”

To be honest, im not exactly sure if it would affect it or not, Im just trying to think about it, you may be right

#### In response to “To be honest, im not exactly sure if it would...”

Well, no it can't be right. Even though you are jumping straight into the air , you still have the same gravitational pull which will pull you down onto the exact same spot. Because if you think of it, if you were to jump straight into the air and the Earth still moves without you, technically you would be thrown into a wall at the same speed of the Earth, which is thousands of miles per second.

#### In response to “Well, no it can't be right. Even though you...”

(EmilyDr-Pepper): even though you are correct in disagreeing with this post you are wrong about the reason why. While the gravitational force will pull you down that has nothing to do with the speed perpendicular to the earth.

#### In response to “Well, no it can't be right. Even though you...”

(EmilyDr-Pepper): So, my question is, what's the difference between our JUMP and someone going in some sort of air-device, let's say a hot air balloon in a secluded area with no wind. Go straight up in the air with the hot air balloon for lets say...12 hours...now go straight down. I don't think the spot will be the same, will it? I have no real insight on this at all, this question is solely out of curioisity and desire to learn.

#### In response to “(EmilyDr-Pepper): So, my question is, what's...”

That will be due to a number of things such as air currents. However, this post is about the earth moving, not other forces that can affect it.

#### Chromana

Have you ever heard of inertia?

#### Bookworm527

why is everyone agreeing? like everyone has commented that you wouldnt lol

try doing it on a train. it still doesnt work.

Nice discussion. :)

I can't even start to explain the fail of this post. You posted a nerdy post so I'm posting a nerdy comment.
This is all about fairly basic physics.
Let's just say that you fire a small ball perfectly upwards in a vacuum chamber. That removes human jumping error and other forces such as air resistance.
The ball starts sitting on its shooting apparatus. It is moving at the same speed through space as the shooter and hence the Earth since they are all connected. They all have relative velocities of zero in any direction.
The ball is then fired upwards. The ball is travelling horizontally at the same speed as the shooter and the earth that is connected to the shooter. The only force affecting the ball is the downwards gravitational pull. This makes the ball return back down to the shooter from exactly where it was fired from.

#### In response to “I can't even start to explain the fail of...”

Here's a really simple alternate explanation:
At the equator the Earth is spinning on its axis at about 1000 miles per hour. If what you say is true then if you throw a ball up it will go flying away from you, since you are moving about 1000 miles per hour. This doesn't happen. Therefore, I've proved you wrong via contradiction.

#### Chromana

Maybe you'd be in a slightly different spot, but only with a difference of like 1/1000 of a millimeter? I wouldn't know...

#### Randomer :)

i know this is horribly wrong, but at least he tried. and failed

#### litapd311

If the earth is always at the same speed, and there are no factors like air resistance, the position you land will be exactly the same as were you started.

#### Anonymous

If you mean rotation movement when you say that the earth will move without you, you also have the same speed as the movement of the earth so while in the air, you would move with the earth, if it wasn't like this, every second you are jumping you would be 30km away from where you started.

#### Neno

How fast is the human body moving anyways? The speed of the Earth's rotation, on top of the speed of the earth's orbit, on top of the speed of the galaxy twisting? How do you figure out the math of that?

#### Propane

Everything within the atmosphere moves with the Earth. You'll land in the same place. :)

#### keeping_the_moon

Maybe if you manage to jump during a major shift in the tectonic plate you were standing on so that it moves beneath you... but that wouldn't be "at any given point". I'm sure the plates move at an infinitesimally small rate, but since inertia has already been discussed, the same effects apply to your relationship with the plate (along with the inertial laws of earthly objects)

#### MaurerPower

It's called the Coriolis effect...
