If we stand in a moving vehicle like train, when it suddenly stops we surely going to fall. Will it be of the same effect when the earth's rotation suddenly stopped?

Good question. Let us not speculate. Let us base our deduction on facts. The rotational speed of Earth is 465.11 m/sec[V] at equator.[ It will reduce at polls.] The mean radius of Earth is 6372.797 km.[R] We can now work out the acceleration due to rotation at any point on the equator.V^2/R.This works out to 3.4cm/sec^2, which is small quantity. Virtually it may not make any affect. The other aspects to consider are. 1] This is a hypothetical question. It will never happen in reality. This is because the rotation will continue due to huge inertia of Earth.It is not possible to conceive of a situation when there could arise an external force to grip and prevent Earth from rotation.2] If this ever happened we will never have day and night as now. The side facing the sun will have day and the other side will have night.

As you pose the question, the answer is yes. It would be the same as riding a train moving about a thousand miles per hour that suddenly stopped.
If whatever made the earth stop rotating applies equally to you, you would not fall. If the inertial mass of you and the earth suddenly became zero, there would be no inertia to keep the earth spinning but there would also be no inertia to keep you moving.

The Earth did stop spinning once in history.
Joshua 10:12 in the Bible. The setting is Israel was being led by God to take the Promised Land. They were to defeat and destroy the Amorites, people who were occupying The Promised Land.
Joshua 10:12 Then Joshua spoke to The Lord in the day when the Lord delivered up the Amorites before the children of Israel:
"Sun, stand still over Gibeon;
And moon, in the Valley of Aijalon."
:13 So the sun stood still,
And the moon stopped,
Till the people had revenge
Upon their enemies.
Is this not written in the Book of Jasher? So the sun stood still in the midst of heaven, and did not hasten to go down for about a whole day.
:14 And there has been no day like that, before it or after it, that The lord heeded the voice of a man: for The Lord fought for Israel.
Oriental legends talk of a day that did not end until the next night.
North and South American Indian legends speak of a night which did not end for a whole day.

As you pose the question, the respond is confident. it may be the comparable as driving a practice shifting some thousand miles in line with hour that unexpectedly stopped. If in spite of made the earth provide up rotating applies the two to you, you does not fall. If the inertial mass of you and the earth unexpectedly grew to develop into 0, there may be no inertia to maintain the earth spinning yet there might additionally be no inertia to maintain you shifting.

You have to have something larger than the mass of the earth to grip the earth, it will not suddenly stop without some sort of friction between the two masses, this will result in nuclear like temperatures, the earths thin crust sits on top of a molten interior.
no way you cant suddenly stop a molten mass from moving. even a small mass molten mass would have trouble stopping. I think it would be the same as trying to juggle three full cups of water, without spilling a drop. (if you can find someone who can do this i would love to see it)

The centrifugal force produced by Earth's rotation (which is nonexistant at the poles and at a maximum at the equator) is insignificant when compared with that of gravity, so the answer is a resounding NO! We would all die horribly, however, since someone at the equator would start moving at around 27,000 /24 mph, more than 1000 mph!

If it suddenly stopped cold in its track, yes.
Of course the shear forces would also rip apart the earth's crust, considering the immense inertia of the earth's mass, so falling down would be the *least* of your problems.

well I think YES.coz with the rotation of earth our body is also in motion that we cant feel n if the earth stops then our body will tend to move and at the same time our feet will be under the influence of gravity and aour upper body will tand to move so its NATURAL that we will surely FALL ..

the gravity doesnt depend on the earth's rotation but rather it depends on the big magnetic field ( virtual ) at centre of earth. and if earth stops rotating, then the side-effectts are like no days or nights and all that.

no you will not even feel that Earth has stopped Rotating,but Earth itself will Fell out of Universe if it stops.
