what keeps the Earth spinning? or more exactly, what drives the planets in our solar system to spin and rotate around the sun? what will happen if earth stop spinning?
Like Russ said, inertia. Space is an ultra-low friction environment. There's not much to slow it down (although it is slowing). The material that came together to form the Earth had a net spin. Plus, collisions by protoplanets, etc. can add energy to the spin. If you think about it, it would be surprising if something like a planet didn't spin.Originally posted by alchemist

Spinning (rotation) - see above.or more exactly, what drives the planets in our solar system to spin and rotate around the sun?
With respect to what? To the sun? If the Earth became gravitationally locked with the sun, then one side would fry and the other would freeze. If this happened slowly, then the change would be slow. If it happened in an instant (magically), then the entire surface of the Earth would be destroyed (think of the effect on you when a car stops suddenly...now consider that the Earth is spinning at about 1,000 mph at the equator).what will happen if earth stop spinning?
