Why does our world spin around itself ?

Answer 1

The main idea is that angular momentum is conseved, ie, cannot change. Angular momentum is the product of the spin rate and the moment of inertia (a measure of the distribution of the mass about the axis of rotation). The product is constant.

If mass is widely dispersed as before condensing into a planet, and is very slowly rotating, then when it condenses into a planet (making a small moment of inertia) the rate of rotation could be large. So condensing amplifies whatever rotation there was initially.

The real interesting question is how did some of the bodies that we know of (Like Venus) get very little pin (it spins around about once every time around the sun)! Same with the Moon (athough if it is a remnant of an collision with Earth it is easier to explain why is has low spin - ahem - excuse me - rotation).

Answer 2

The Palestinians p.c.. to make specific the Israeli state close down and function finished their utmost over the years to purpose this. The use hands to hearth into Israel and subsequently the Gaza embargo is in place. Why have been there countless grownup adult adult males on a small furnish allegedly wearing an easy cargo, different than it grew to advance right into a protection tension conserving hands being carried to break the embargo. Israel might have gained a tip off and took action. i'm now no longer a Jew. I inspite of the shown fact that undergo in recommendations that they murdered British infantrymen indoors the overdue Nineteen Forties, yet so did countless diverse international locations in that decade.

Answer 3

The dynamics of a rotating body are controlled by forces like gravity and conserved angular momentum from initial conditions when the solar system formed.

Personally, I am not sure that this explanation fully explains the phenomena.

Answer 4

I suppose it would be more remarkable if our world did not spin.
If planets are created by the coalescing of a spinning cloud of gas (one theory) then that rotation is passed along in the nearly frictionless void of space to the resulting planet.

Answer 5

the universe don't spins around it self exactly,
but our galaxy does,
also, the whole universe is growing..!

Answer 6

This is a good question.

Carl Sagan was a popular scientist who tried to answer this question. I think he does it better justice than I could, so I'm putting a link to his website below.
