if everyone in the world jumped up and down at once, would the earth really loose orbit?

Answer 1

I think that by hopping, you could exert maybe 100 pounds of force on the Earth. Six billion people would then exert 0.6 trillion pounds of force. That's 6 followed by 11 zeroes.

The weight of the Earth is 1.317 x 10^25 pounds. that's 1317 followed by 22 zeroes. 22-11 = 11. So we are talking about one unit of force attempting to influence an object with 100 billion units of force. There is no way this would move the Earth even one millimeter, let alone take it out of its orbit.

Answer 2

You couldnt get everyone to do it at the same time because of the delay in communicating "GO!" around the world at exactly the same time.
If you don't take that into account, everyone would jump and then decend at a slightly different rate (long/short legs, weak/strong muscles etc) so even if they could be all told to jump at the same time, the resultant jumps still wouldnt be in sync.
If you don't take THAT into account, the mass of everyone in the world verses the mass of the earth would be like 5 ants jumping on a hot air balloon trying to get it to go down.

Answer 3

I've never heard of that theory, so it's probable that it's not true. I have heard, however, that if the whole world's population, as much as China alone, jumps at the same time the earth would explode from its core because so much force by weight is exerted and the pressure causes the inner core to collapse in itself.

Answer 4

definite quickly (till the guy lands) yet finally no.... different than with a million loop hollow. The definite, is that as quickly as even a million individual jumps (no longer to show all and sundry), they exert a tension that pushes the Earth far off from them, as properly pushing themselves into the air. it somewhat is basically Newton's third regulation - "to each action there is an equivalent and opposite reaction." The tension on earth whilst the guy jumps up, is a similar because of the fact the stress on the guy. even nonetheless you're able to be able to recollect F=ma from physics. tension = mass X acceleration Rearrange that, we get , Acceleration = tension / mass Now given the earth weighs trillions of circumstances greater the guy, the acceleration of the Earth far off from the guy is going to be trillions of circumstances below the guy's acceleration far off from the Earth. yet there is a few flow. even nonetheless, what occurs whilst the guy lands? finally we return to our unique state. it somewhat is from yet another uncomplicated physics concept - conservation of momentum. think of a pair of spaceship as an analogy. If the astronaut jumps around as a replace the spaceship, it has no result on the spaceships action. even nonetheless there is the thank you to go the spaceship. specifically, to throw rocket exhaust (or astronauts to throw themselves) out of the spaceship. So likewise, if a individual could leap quickly adequate to flee the Earth (it occurs to be 7 miles in line with 2nd - approximately 25,000 miles in line with hour), they could reason a internet result on earth's flow.

Answer 5

No. When you jump you push off with the same energy that you return when you come back down, so the resultant force is zero.

Answer 6

interesting question. many possibilities for a science fic.

No, you would not course the earth to leave its orbit, or collapse

Answer 7

No. everything cancels its self out.
Now if you asked if everyone started running from north to south at the same time, that could potentially have consequences.

Answer 8

NO

Because we are so puny compared with the mass of the world and it wouldn't get loose because it's not tied on.

Answer 9

no the world is round .we would be putting roughly the same presser all the way round

Answer 10

i dunno...but that would be cool
