When do you feel ur motion?only when u r moving with respect to a stationary object.Similarly if the earth rotates with u at rest u can feel it move.Since u r moving with the earth u can't feel it.(relativity)

The formula for centrifugal force (which is what you feel when spinning) is F=Rw^2. In this, R is your distance from the axis of rotation and w is the angle that is rotated in one second. For the case of the earth, even though R is large (4000 miles), the w is very small (the amount the earth rotates in one second is not very much). Furthermore, w is squared, so that makes the force even smaller. The end result is that the force is small.

Now, the velocity of rotation is v=Rw. This is still large for the earth (again, R is large and w is small). You can see that F=v*w. Even though v is large, w is small and the product is small.


Those saying that there is no acceleration are WRONG. There is, but it is a change in direction, not a change in speed. This still causes a force. It's just that for the earth, that force is small.

You never feel smooth motion - you only feel acceleration.

Now of course the rotation of the Earth means that you are indeed accelerating - circular motion always requires acceleration towards the centre of the circle.

However, the acceleration due to the rotation of the Earth is only about 1% of the acceleration due to gravity, so you simply do not notice it. It is also, of course, in the same direction.

through fact we are on it and shifting by using area on the comparable speed. additionally you in undemanding terms sense speed while it placed against a background that has a diverse speed or isn't shifting. Distance to the background is relative to boot eg. if the backgorund is a lot away u wont sense such as you're going quickly. even with the undeniable fact that if the background is close it provides u the concept which you're going quickly even nonetheless u could not be. evaluate looking out of the window of a airplane and a convention. additionally the gravity of the earth keeps you tied to its movements

Half a bottle of sake and anyone can feel the Earth's rotation.

On the other hand, you need drugs to feel the Earth's revolution around the Sun.

LSD can alow you to feel all that AND the revolution of the Sun around the Galactic Core.

It called relative motion, and since you are on the earth and traveling at the same speed as the earth you will not feel the motion. Because your relative speed with respect to the earth is zero.

Because it is too slow. It takes all day and all night to go one time around. If you were sitting on a merry-go-round turning that slowly, you would not be able to feel that motion either.

Due to the atmosphere and gravity's forces working together, the Earth is like a magnet that is holding us with gravity, and the atmosphere makes it so we can't feel the movement

We would if it were spinning really fast, but it isn't. It takes 24 whole hours to make just 1 rotation.

The earth's rotation is constant. It's the same reason you don't feel like your flying really fast when you're in an airplane. You feel CHANGES in speed, not the speed itself.
