Want this question answered?
ummmmmmmmmm yea i dont know thats why i came here! Well you know what people, no one really cares for what you put. We need the right answer!!!
Gravataional force is applied by the spinning of the earth.
No, the atmosphere is held in place by gravity, not centripetal force. If the earth stopped spinning, there would be no coriolis force though. This would stop deflecting the moving air in the atmosphere.
Earth Defense Force was created on 1991-10-25.
When the earth is spinning, the rotation along with gravity creates centrifugal force. This is the same as the force that happens when you swing a yo-yo around by the string, the string is like gravity in that scenario holding the yo-yo close to you.
No. Once an object starts spinning it does not need anything to keep it spinning. In fact it would take a force to stop the rotation. Earth has been rotating since it first formed and its angular momentum has kept it spinning.
No, it is the mass of the Earth that keeps it spinning steadily. The Earth is in free fall going round the Sun so it feels no force on it. The force is exactly balanced by acceleration towards the Sun. But because the Earth is big and the Sun relatively close, the point of Earth nearest the Sun (where the Sun is overhead) has a little more force than the centre, and twice as much as at the opposite point, and the difference is called a tidal force.
Prefectural Earth Defense Force was created on 1986-03-21.
Centrifugal force .
used by spinning motion of the earth around its axis passing through the poles...the force being max at the equator...since at tym of formation, earth was in fluid state, the force of cohesion was small & could not balance the centrifugal force...hence it bulged out at the equator
The earth wont stop spinning unless something big hits it - then we would all die from the collision. A counter rotational force is required to stop the earths spin, otherwise it will just go on rotating.
"Wobble" isn't a very precise term.The Earth has a small, short period "wobble" simply due to the fact that it isn't perfectly symmetrical and balanced.This also causes a small, longer period "wobble" due to the effect of the Moon's gravity on the (slightly asymmetric) Earth.And there are wobbles due to other (and to me unknown) causes.But I suspect what you're talking about is what's technically called precession, which has a special name because it's a very particular type of "wobble". The Earth precesses on its axis in a cycle lasting about 29,000 years. Because of this, Summer 15,000 years ago ... or 15,000 years from now... would have occurred in the northern hemisphere in December rather than June.
