How many miles an hour does the Earth spin, and what keeps it from affecting us?

Answer 1

A little over 1000 mph at the equator...zero at the poles. Gravity keeps us firmly on the surface. However, the Earth's spin is not accelerating. It's the same way that when you're in an airplane going 500 mph, you don't feel that either. It's because everything around you is moving at the same speed. You feel it as you speed up (accelerate) but once you reach cruising speed, you don't feel it anymore.

Answer 2

The Earth spins at (the circumference at the equator) per day. If this is a measurable speed, then it spins at this rate at any point on Earth. That is to say, the Earth spins at the speed of X. You might travel a greater distance at the equator, but standing on the north pole you will be spinning just as fast.
And nothing keeps it from affecting us. If you live in a region with night and day, then your body clock is attuned to these changes. If you were to move to the north pole to escape the daily grind, then you would be depressed for half the year. I wish my name was Spin Doctor.

Answer 3

the Earth rotates once in 24 hours, and its (equatorial) radius is 3,963 miles (6,378 km). As with the Moon, the rotational speed starts at zero at either geographic pole and increases as you head toward the equator, where it reaches its maximum of about 1038 mi/hr (1669 km/hr). At 45 degrees north or south latitude, the
rotational speed is about 0.7 of this maximum speed.

Well we don't feel anything because all of the motions are almost completely constant.

When you take a really smooth plane or train ride, you don't feel the motion unless the plane/train slows down, speeds up, or hits a bump in the road. So as long as there is constant motion, we don't feel it.

There is also another way in which we could indirectly feel the Earth's spin. Above we said that the Earth spinning is an example of almost constant motion. The reason we said "almost" is that the Earth's spin carries us around in a circle, not in a straight line. It's a very big circle, and it takes a long time to go around, but qualitatively it is the same thing that happens on a spinning amusement park ride, where it feels like you're being flung outward as the ride spins around. The spinning Earth is flinging us away from its surface a tiny bit, so that we weigh a little less than we would otherwise, simply because we are not being held down to the surface as tightly.

Answer 4

The Earth at the equator is 24,902 mile saround. The earth rotates once every 23hr 56 or 23.933 hours. Therefore, the Earth spins at 1040.488 mph. Or in laymen's terms, pretty darn fast.

Answer 5

Haven't you ever gotten out of bed fast and felt dizzy? (just kidding)

Even though the earth spins quickly, the atmosphere spins at the same rate, so we aren't aware of the motion. Consider sitting in a airplane traveling at 1000mi/hr. - you won't feel the motion as long as the plane doesn't accelerate or deaccelerate.

Answer 6

Don't forget our solar system is spinning around the Milky Way Galaxy and the galaxy itself is traveling away from the center of the Universe. So, you need to add those speeds to you calculations too.....

Answer 7

At the equator, the circumference of the earth is 24,902 miles, and it revolves in 24 hours, so (24,902/24 = 1,037.6 miles per hour). It does affect us, it creates weather. We stay in place due to gravity and friction.

Answer 8

About 1000mph at the equator and lessens as you move away from the equator. It does affect us but our atmosphere and gravity all play a role in how it affects us.

Answer 9

1041.666666667 mph. Gravity is the key!
