Why don't we feel the world spinning'?

Answer 1

because it spins sooooooooo slowly

Answer 2

It turns out that not only is the Earth spinning on its axis, but it is orbiting around the sun, which is in turn making its way around the galactic center at speeds of several hundreds of kilometers per second. The reason we don't feel it can be explained by thinking of an airplane ride. Imagine we are in a perfect airplane. That is, an airplane that is flying at a constant velocity without slowing down, speeding up, turbulence or turning. In this airplane, we are free to move about without noticing that the plane is moving. We can run, walk, play catch and do anything that we can do on the ground because we are moving at the same constant velocity as the airplane. In fact, if the windows were closed, there is no way we could tell whether we were flying along at this constant velocity or whether we were sitting motionless on the runway. If, however, the pilot decides to speed up, slow down, or turn, the plane undergoes an acceleration and we can feel an inertial force. Think of making a fast left turn in a car. You feel an inertial force pushing you to the right as a result of your frame or reference (in this case the car) undergoing an acceleration (the sharp left turn). Like the plane, our solar system is moving very close to a constant velocity. So, just as in the plane, we can't feel that we are moving through space. Although the Earth is moving in a curved path around the sun, which means it is undergoing an acceleration, the inertial force is so small that we don't feel it. We can however measure an inertial force caused by the earth's rotation. This force is called the Coreolis force and it plays an important role in our climate and weather planes.

Answer 3

Very important fact, that comes up in hundreds of situations . . . . . We never feel motion.

We only feel changes in motion.

Example: You can read or sleep very well in a car going 70 miles an hour, as long as the

car doesn't speed up, slow down, turn, or hit a rough spot. And have you ever been on

an airliner, cruising along at 400 miles an hour and reading a book or taking a nap ?

It makes no difference whether you're moving fast or slow, horizontally or vertically.

You feel nothing until either the speed or the direction changes.

On the spinning earth, you're moving almost 1,040 miles an hour at the equator, or

730 miles an hour at the latitude of Chicago. You don't feel the speed in the direction

east along the ground, because it never changes. You do feel the force it takes to

keep you moving in a circle at that speed ... the force you call your "weight".

Answer 4

The angular speed is quite low - once every 24 hours. At such a low angular speed, and for an object the size of our body, the Coriolis effects are quite insignificant.
