how does earth acquire the power to rotate abt its axis?

Answer 1

The energy came from when the solar system was originally formed. When gas, matter etc come together (due to gravity) it always rotates. Earth still has that rotational energy, and it is conserved as there is nothing to slow it down - space is a vacuum, and so there's nothing like 'air resistance' to get in the way. As such, unless something really, really, big hits Earth, it will never stop spinning, because the orginal rotational energy it has will never go away.

Answer 2

Laurelin is correct. The whole concept can be associated to the formation of the solar system. As the planets are formed from matter that exploded out of the Sun. The explosion made the matter start revolving about its own axis. and while cooling down too .. they kept rotating. This rotaion is the reason for the spherical shape of all planets. and that the equitorial axis is longer than the polar axis.

Answer 3

it doesnt.

the spin was put on it in the early phases of its development, when it was still a cloud of gas of dust... the differing pull of outer gravity sources on opposite sides of the cloud made it spin VERY SLOWLY. this spin became much faster when it began to collapse into its own center. this is basically the same effect that makes water rotate as it goes down the drain.

since the atmosphere, or its earliest form, developed from the same cosmic cloud, it has the same impulse and rotates at the same rate as the planet. since the whole thing is in space, there is no friction to slow the spin down, and so it keeps spinning and spinning.

of course... space is not completely empty, much less inside a solar system... and ther is a LITTLE friction. and as it so happens, there seem to be several hints in the behavior of plants and primitive animals, that suggest that the days may have been a bit shorter in earlier ages. nothing substantial so far, though.

Answer 4

Earth acquires the power to rotate about itz axis by the gravitational and centrifugal force of the sun.

Answer 5

The Earth is supposed to have been borm from the Big Bang. The gravitational forces of other stellar objects acts around it is like a Curd churner which were in use in olden days with a string wraped around it. This effect occurs due to the action of various forces. Modern day string theory helps us to model these movements.

Answer 6

It seems to be rotating becouse of its revolving along its orbit around sun. The earth may stop rotating around its axis when it stops orbitting around sun. Some machines seems to be based on this principle.

And earth seems to be orbitting around the sun becouse of gravitational force exerted not only by sun but also by sources all around the space. The space seems to have a number of orbital paths located at diffrent points.

All the objects tends to move along their respective orbits irrespective of their mass or size. Some segments of space may be moving in clockwise direction and some others in anticlockwise directions. All objects falling in one particular path may travel at same speed irrespective of their mass and size. It suggest that diffrent segments of space itself do travel and planets stars and other celestial bodies move alongwith their respective space segments.

Answer 7

it rotates due 2 d centripetal force of its own gravity

Answer 8

the earth does not spin!!!
it is a flat disc, and if you get too close to the edge you may fall off.
WATCH OUT !!!

Answer 9

God spins it like a gaint basketball on his finger

Answer 10

gravitational pull by the sun
