if the world is spining so fast how come when you jump in the air you dont land some where else?

Answer 1

Thats why you should NEVER jump in the air!!! You might land in a different country

Answer 2

The answer is to do with relativity. When you jump straight up on the surface of the earth you will land on the same spot on the earth but NOT the same spot in space (because the earth and you have both moved). This is because you are moving at the same relative velocity as the earth.
Imagine you are standing IN a moving train going past a train station and you jump. You will land on the same spot in the train because you are going at the same relative velocity as the train.
But an observer standing still on the train station platform will see you jump in an arc and land in a different spot.
Its all relative and nothing to do with gravity. Gravity is the reason you land back on the earth and not fly off into space when you jump.

Answer 3

because the air is spinning with the earth also, and it pulls you with earth so you can't land........ How high can you jump???

It is not only the earth that has angular momentum (ie, spinning so fast), but also all things on earth that have this momentum.

Don't believe me? Put a push-pin into the side of a globe and spin it. The push-pin moves with the surface of the globe. It is 'stuck' to it. In the same way, you and I are 'stuck' to the surface of the earth by the force of gravity, which is strong enough to keep the moon moving around the earth, even though it is hundreds of thousands of miles away. If the gravitational pull of the earth on the moon can keep the moon tethered, it will certainly keep you there as well.

So why don't we notice the spinning? We have no frame of reference to compare it to. Everything around us is 'spinning' with the earth. This is why all celestial objects (stars, sun, moon) seem to rotate around the earth.

momentum keep you in the same spot. When you are "standing still", you [well if you're near the equator] are moving along with the earth's surface at approximately 1,000mph. You don't notice this motion since, to anyone inside the earth's gravity well, it is our stationary frame of reference. You never feel "motion" unless you accelerate. When going along in your car on a smooth road and if you couldn't see things moving past you out the window, you wouldn't feel you were moving unless you sped up/braked or turned, but you are moving. So, even though you think you jump straight up and then straight down, you really jump in an arc going from west to east. Unless of course, when you jump you can achieve escape velocity like eventually rockets do, then you won't land in the same spot because you will have separated yourself out of the earth's gravity well. However, you would have to attain escape velocity immediately, otherwise like a rocket, your first part of jump will arc toward the east. [This is why governments place launch sites as close as possible to the equator, most transfer of energy from earth's spin to rocket.]

Answer 5

Ahh...gravitational relativity.

It is not only the earth that has angular momentum (ie, spinning so fast), but also all things on earth that have this momentum.

Don't believe me? Put a push-pin into the side of a globe and spin it. The push-pin moves with the surface of the globe. It is 'stuck' to it. In the same way, you and I are 'stuck' to the surface of the earth by the force of gravity, which is strong enough to keep the moon moving around the earth, even though it is hundreds of thousands of miles away.

Answer 6

As other people have said - because you're spinning with it.

it's like - if you're on a train which is going at a constant speed and you jump in the air, you land on the same spot in the train - because you're travelling at the same speed as the train. To someone standing on a station platform as you went by, you'd look as though you'd jumped forward, relative to them.

Answer 7

Well, you are moving at the same speed of the planet, so when you jump up, you are also jumping towards the east at the same speed as the ground underneath you, so you land in the same spot you jumped from.

Answer 8

We are moving at the same speed as earth, approximately 1000 mph. Which is why if the Earth were to suddenly stop spinning, we would go flying off into the atmosphere.

Answer 9

the answer is inertia. you are moving with the earth so when you jump you are still moving in the same direction and you dont slow down enough to land in a different spot. if you jumped high enough then you deffinitely land in another spot

Answer 10

Your spining with it and even if your trajectory goes just a little bit of end you can't notest it remenber that the earth radius is 6372Km so 1 m in plus isn't really much

Answer 11

Becasue when you jump, you are spinning just as fast as the earth; so tie that in with gravity and there you go...same spot.
