Where dose the earth get it's energy from to spin?

Answer 1

Earth doesn't take up any more energy to maintain the spin, and slows down gradually as tidal forces counteract the rotation ever so slightly.

The original momentum for the rotation probably resulted from the collisions which formed the earth. Once the _huge_ mass of earth was rotating, a huge rotational moment was there.

According to one theory the moon was formed when a smaller earth was hit by a planet somewhat larger than our current moon. As a result the planet liquified (once again), and ejected our current moon, taking up much of the mass of the colliding planet. I suppose this will have affected rotation (and rotational tilt) somewhat, but I have no idea in which order of magnitude.

Answer 2

It keeps spinning because there is no force acting on it to slow it down and stop it -- not because it is getting energy from anywhere that it uses to spin .

When you spin a ball on a table it slows down because of the friction of the air and the table against the surface of the ball.

However the air around the earth moves with the Earth. It does not stay still and drag against the earth's surface. So there is no consistent friction against the surface of the Earth. Also, there is no friction against our atmosphere because there is only an relatively empty vacum in space next to it. Nothing to rub against.

If a big meteorite hits the earth however it could change the speed of our rotation. Perhaps we could have 6 hour days. Then we would only have to go to work for about 3 hours!

Answer 3

There are not the different spinning universes. they're called galaxies. there is in easy terms one Universe. we do no longer be responsive to if the Universe is cyclical. it appears that evidently to be increasing. If our estimates of that fee of enlargement and mass are everywhere close to to being applicable, then that's going to proceed to strengthen until all depend decomposes and all skill for interactions has reached digital 0. warmth loss of existence. some have proposed a Universe which expands and then collapses gravitationally. Then by some ability, starts off a sparkling huge Bang. This form nevertheless implies in easy terms one Universe, even nevertheless that's cyclical. This has been oftentimes deserted because of the fact there is no longer almost sufficient mass, (given our estimate of enlargement.) The universe does no longer be a device by way of any definition because of the fact it has no output. each and every thing is contained interior it. that's not a device interior the comparable way a pendulum isn't a device. The Universe would properly be recognized as a substantial clock, yet time isn't a sturdy analogy for existence. Time is a quantity -- a length. existence is a actual technique. it would be like comparing length to morality. maximum galaxies do rotate, exceptionally spiral galaxies. The additionally evolve. there remains lots to be found out approximately galactic evolution.

Answer 4

To answer this question one has to look at how the Earth was formed.

Imagine first that you have abunch of marbles on the floor all with the same size and mass except one big marble. Now assume that the floor is frictionless and there is now gravity. If all of the marbles were the same mass and evenly spread then the tendancy is to stay evenly spread (no planet).

However if in one region there is more marbles (or just a big marble) the others tend to be attract to that space.

Now as the marbles roll in they tend to collide with other marbles and not hit the big marble dierctly in teh center but off center, hence the colliding marbles tend to orbit around the big marble in various directions. Eventually through collisions all of the colliding marbles are orbiting in a single direction (collisions eventually result in a a single direction). So in essence if 3 marbles were orbiting clockwise and 2 counterclockwise, eventually collisions would stop two marbles but teh uncollided one would still rotate counterclockwise, hence some direction would result (some spin direction).

Over time, via collisions, all of teh marbles would be spinning around the big marble in teh same direction, and eventually combine with teh big marble to form a big spinning marble planet.

Now in place of teh marbles put tiny gas molecules, and then you have a real spinning planet.

Hope this helps.

Answer 5

When a spinning figure skater pulls in her arms she spins faster and faster because of conservation of angular momentum. If the earth was formed from a mass of swirling gas and other matter, as the mass consolidated and heavier metals like iron and nickle sank to the center, the spin would increase. The earth spins in a vacuum and there is no friction to slow it down. Therefore it will spin practically forever.

Answer 6

From the pull of multiple gravity fields from sun, moon and other stellar objects and its own momentum since there would be no friction to stop the spinning..at least i think that is why

Answer 7

From the starving people of the world....these starving, poor people don't get enough to eat because this earth takes it away from them...just to satisfy its own hobby of spinning....

Answer 8

The gravitational pull of the sun along with the offset of its own gravity

Answer 9

From all the other planets, they work in conjunction with one another, with the sun being the focal point.
