What would happen if there would be no gravitional force?

Question

It is homework for 2morow so what would happen with us and the planets that need gravity

Answer 1

if there were no gravity, the universe as we know it would not exists. No gravity would mean that matter would not have coalesced into the galaxies and stars and planets that we know today.

If, on the other hand, one were to start with the universe as we know it today and simply flip the switch to turn off gravity, everything in the universe would simply fly apart under its own inertia. The planets would fly out of their orbits, and would fly apart under the force of their own rotation.

Answer 2

If the gravitational force were suddenly to disappear, the sun and all the planets (and all the other stars and planets in the galaxy) would suddenly explode violently. This is because there is a huge amount of outward pressure inside every star and planet. In everything that is big enough to be pulled into a round shape by gravity, there is a balance between the inward pull of gravity and the outward push of the internal pressure. If you remove the gravity, that internal pressure is released, and Kaboom!

Very small bodies (say, comets and other things that are only a few miles across or smaller) would "survive" (they wouldn't explode).

If there were _never_ any gravitational force, there would have been no stars, planets or galaxies in the first place.

Answer 3

Without gravity the Sun would stop shining, gravity produces the high pressure deep inside the Sun to initiate fusion. The air and water would fly away from the Earth, all the planets would break apart without gravity to hold them together, the galaxies would rip apart, there would be no life.

If there never was gravity in the universe in the first place, there wouldn't be a Universe to begin with.

Answer 4

If suddenly, the last person to leave the solar system turned off the gravity, several things would happen... First, all of the planets and all of their moons would stop orbiting and shoot off along their last vector (making the System a much more exciting place to live - If only briefly).

Then, as the Earth shot off like a bullet we would all accelerate upwards and away from the direction of travel due to the unchecked centrifugal force of our rapidly spinning planet.

By the same process, the atmosphere and water would leach away behind us like a fantasic comet's tail.. Followed closely by millions of cars, boats, TVs and George Foreman Grills..

The sun would get smaller as we sped away and any trapped water would freeze, as would anyone who had been trapped anywhere with an air supply..

Answer 5

This question as as old and asked as often as "what is 1 + 1?". In order to maintain the definition of this contradictory statement the unstoppable force has to pass thru the immovable object with no interaction whatsoever. Any other conclusion contradicts the initial conditions.

Answer 6

Ooh, so many different things. First, we wouldn't orbit the sun, so we wouldn't have the ideal conditions we have that allow life to thrive on this planet. Second, as there would be no life on this planet, you wouldn't have to answer such daft question as homework.

Answer 7

The planets would just be moving in straight lines with no sun, moon, atmosphere, oceans or people. If someone gave you this for homework, they should be fired. It's situation that has not nor will it ever occur.

Answer 8

no life, no planets, no stars would ever exist. The Big bang would start out bright, but eventually dim to near nothing.

Answer 9

Gravity (as well as magnetic field) helps the atmosphere to stay in place. Without atmosphere no life could exist. No Wasp, flea, rabbit, cheetah, dog or person. How sad.

Answer 10

Please look it up, or you will be at a loss later, as you will not remeber the answer when you need it again. Use the web if you must. Gravity.
