if everyone jumped in the air at exactly the same time would it affect the stability of the planet?

Answer 1

No. The mass of the planet is on the order of a trillion times the mass of all the humans on it.

Answer 2

THIS WAS MY ANSWER TO AN EARLIER QUESTION ABOUT SLOWING OR SPEEDING UP THE EARTH BY ALL JUMPING. THE MATHS IS PRETTY MUCH THE SAME.

However, I agree with the earlier answer which was why not do a search for the answer first?

Jumping up would make no difference whatsoever to the earths rotational speed as the force would act through the earths centre of gravity. However, jumping forward or backward would temporarily affect the rotational speed.

However, the mass of the earth is 5.9742×10^24 kg. The earth's human population is approx 6.5*10^9 so as a ratio we are approx 50/10^15th of the world mass (assuming we each wigh 50kg on average) or a 20 thousand billionth of the total. I can't see the world bothering to notice.

In time terms, if all humanity was a second, the world in comparison would be 633762 years old.

Interesting question though, unfortunately I now feel really really small as if all humanity was a second I'm just a 1/6 of a nanosecond.

Answer 3

When 1 individual person jumps you exert a force on the Earth and the Earth exerts the same force back. as you move... the Earth moves an equivalent distance relative to your differing masses. If everybody on the planet did this simultaneously then given the spread of population across the globe there would be no noticeable effect - with the possible exception of minor earth quakes around China & India.

If everybody gathered in one place then the effect would be greater with regards the Earth quake but the combined mass of all the people on the planet is still very small compared to that of the Earth & it would not effect the planets orbit in any way.

Answer 4

THIS replaced into MY answer TO AN interior the previous question about SLOWING OR rushing UP THE EARTH by using ability of ALL jumping. the maths is fantastically a lot an same. even if, I believe the speedier answer which replaced into why not do a search for for the answer first? jumping up can make no distinction in any delight in to the earths rotational velocity by using actuality the pressure might want to act by skill of the time of the earths centre of gravity. even if, jumping ahead or backward might want to rapidly impression the rotational velocity. even if, the mass of the earth is 5.9742×10^24 kg. The earth's human inhabitants is approx 6.5*10^9 so as a ratio we are approx 50/10^15th of the global mass (assuming we each and each and every wigh 50kg on widespread) or a 20 thousand billionth of the achieved. i'm unable to substantiate the global bothering to observe. In time words, if all humanity replaced accurate right into a second, the global in evaluation will be 633762 years previous. interesting question even if, regrettably I now sense particularly particularly small as although all humanity replaced accurate right into a second i'm in basic terms a a million/6 of a nanosecond.

Answer 5

If there was 10 billion persons in the world, (there is less), and each person weighs on average 90 kilograms, (the average is less), the mass of the planet is 6 trillion times greater than all the people on the world.
(That's 6 with 12 zero's after it.)
This can't possibly affect the stability of the planet in any way.

Answer 6

Yes, the world would shake! Send a world wide email and have everyone try at on August 12, 2010 @ 1:21:32 pm
Good Luck!

Answer 7

It COULD...but it's on a much to great of scale...

On a smaller scale, however, there was a bridge that was destroyed because there were a bunch of tractor trailors on it and they had all stopped. At the time all the engines were set to idol at a set RPM...the rotation of all the motors at the same speed set the bridge in motion in a rocking fashon and it was destroyed

Answer 8

It would depend on the distribution of the population, and as 70% of land mass lies above the Equator that might influence the outcome.

Answer 9

Theoretically it would cause a small brief change, but in reality it would be far to small to detect. Kind of like adding one drop of water to a swimming pool theoretically raises the water level a little, but not enough to detect, even with precise instruments.

Answer 10

Certainly not. Our total mass is negligible compared to Earth's enourmous mass.
Besides, we are spread out almost evenly around the earth. so a pull from one direction would be neutralized by a pull from the opposite direction.
