why does the earth spin?

Question

electron, earth and sun spin why?

WHY DOES ELECTRON, EARTH,SUN AND GALAXIES SPIN?
WHAT MAKE THEM TO SPIN?
I MEAN WHICH FORCES/TORQUE?
PLEASE EXPLAIN USING FIGURES

Answer 1

Current theory holds that the earth, sun and all of the other planets and stars not just here, but throughout the entire universe are formed when clumps of gas form in a cloud of interstellar gas and as these clumps condense through the effect of gravity. As these clumps attract the surrounding material, they start to rotate.

Answer 2

The Earth spins on its axis because of conservation of angular momentum. The classic example of this is a figure skater. When a figure skater pulls in her arms, she spins faster. The Earth formed when gas left over from making the Sun condensed into the planets. As this gas cooled and condensed, it started to spin faster. Now that it is spinning (and not condensing any more), it will keep spinning at a steady rate unless something stops it.

At the equator, the Earth is spinning at 1000 miles per hour about its axis and moving at 67,000 miles per hour around the Sun. With all this motion, you would expect to feel something, right? Well we don't feel anything because all of the motions are almost completely constant.

When you take a really smooth plane or train ride, you don't feel the motion unless the plane/train slows down, speeds up, or hits a bump in the road. So as long as there is constant motion, we don't feel it. Children do amaze me with their ability to perceive things, but I would be very surprised if your daughter could feel the slight wobbles the Earth has as it spins. I don't think the wobbles would be enough (could we feel them) to make someone dizzy.

There is also another way in which we could indirectly feel the Earth's spin. Above we said that the Earth spinning is an example of almost constant motion. The reason we said "almost" is that the Earth's spin carries us around in a circle, not in a straight line. It's a very big circle, and it takes a long time to go around, but qualitatively it is the same thing that happens on a spinning amusement park ride, where it feels like you're being flung outward as the ride spins around. The spinning Earth is flinging us away from its surface a tiny bit, so that we weigh a little less than we would otherwise, simply because we are not being held down to the surface as tightly.

However, this is a very small effect. At the equator, your weight is reduced (compared to a non-spinning Earth) by about 0.3%; the effect weakens as you go north or south, and once you reach the north or south pole it disappears completely because the Earth is not spinning there. So if you can feel differences in your weight of 0.3% (about half a pound for a 150 pound person), and if you travel from the equator to the north or south pole, then technically speaking, you could feel the effects of the Earth spinning. On the other hand, people's weight naturally fluctuates more than 0.3%, so it's unlikely that you'd be able to disentangle this from other effects (like whether or not you had just eaten lunch).

Answer 3

Natural and imposible to explain that exactly.
My imagination is.. the earth and the sun were the materials expelled from big bang , when the velocity of the thrown mater gone down and the distance from the core increases they started attracting each other. Sun was strong (too dense and more gravity) that attracted the earth , the earth started moving towards the sun when it is too close to the sun the electromagnetic waves or some other waves from the sun reaches sufficiently to the earth and refules the earth ,the earth reflects the same waves and get repelled , reaches a distance until the repelling waves lost then again earth is attracted by the sun .... that is why the earth rotates the sun in a elliptical orbit.
the space rocks attracted by the sun and which intrefered by the earth has changed the composition of the earth it started cooling
, water and salt were the major products of the reaction.

Answer 4

The reasons why electrons spin is not at all related to the reasons why the earth and the sun spins. Electron spin turns out to be a relativistic quantum property arising from Dirac's equation, one which behaves like spin, but nobody really knows how it is "spinning". The use of a "spinning top model" for the electron is only figurative, it is not meant to suggest that electrons are like tiny hard balls spinning. It's much more exotic than that.

The earth and the sun, as well as the solar system, on the other hand, comes from the fact any random cloud of gas and dust in interstellar space is statistically likely to have a non-zero net angular momentum. When the cloud collapses under its own gravity, it spins faster, like how ice skaters spin faster when they pull their arms in. The sun, the planets, even their orbits, all have their angular momenta from the net angular momentum of the original interstellar cloud. As with energy and momentum, angular momentum is another conserved quantity.

Answer 5

Earth spins because of the gravitational force of the sun and that of the moon.

Answer 6

Electrons don't spin like macro objects. It's an entirely different phenomenon.

The Earth and Sun spin because they coalesced out of spinning dust in the primordial solar system. Once in motion, it stays in motion.

Answer 7

There is gravitational force between the sun and earth. This force is attractive in nature.So, earth and sun may collapse with each other.To avoid it this collision, earth spins so that proper centripetal force may be provided to over come the phenomena.

Answer 8

Every object in the universe spins. Every object moves.

So, not do so is the aberration.

You must think spacially when looking beyond Earth. It's a different mindset. Stationary is an earthly concept, and really only means "stationary in relation to another object".

Answer 9

usually earth apart from electron and sun,rotate around the sun from west to east .this action is done due to the gravitational force of the planets. due this action we do get sunlight in our days

Answer 10

if you mean orbit thats gravity vs. centrifugal forcelike swinging a yo yo on a string molcules are only small solar systems the fun part is that the space between the nucleus and the electrons is perportionally the same as our solar system rela tive to there size.
