gravity
Speed has no effect on you, and you can't even feel it. What you feel is changes ineither the speed or the direction of your motion. (Those changes are called "acceleration".)Even on Earth, or at least near it, you can move at 500 mles per hour in an airliner, and it'sso smooth that you can read a book or doze off.
You can't feel the movement of Earth as it revolves around its axis, around the sun in its orbit, around the center of the Milky Way galaxy or as part of the Milky Way as it moves through the universe. These movements would require an ability to sense velocity which human beings cannot do. We an however feel rapid acceleration or changes of acceleration. These occur during earthquakes and volcanic events. Essentially the local area of the Earth shakes.
No. The earth is rotating (rather quickly, actually; at my latitude it amounts to about 700 miles per hour), but since we're spinning with it and the angular speed is slow (15 degrees per hour) we don't really notice.
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
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 thecar doesn't speed up, slow down, turn, or hit a rough spot. And have you ever been onan airliner, cruising along at 400 miles an hour while you read a book or take 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, or730 miles an hour at the latitude of Chicago. You don't feel the speed in the directioneast along the ground, because it never changes. You do feel the force it takes tokeep you moving in a circle at that speed ... the force you call your "weight".
Its because all of these movements are constant, they are not accelerating or slowing down. We only feel a force when there is acceleration or decelleration. If you accelerate in a car, you are pushed back into your seat as the force effects you and everything in the vehicle. But at constant speed in a straight line, you can move about normally, as if you were at a standstill.
Because the Earth revolving creates the gravity that makes you stick to the surface.
because you are travelling at the same speed, there is no acceleration
For most of human history on Earth, everybody did. It is plainly demonstrated and confirmed by all of our senses. We feel the Earth solid and motionless under our feet, and we clearly see everything in the sky revolving around us every day.
Humans are traveling at the same speed as the earth.
because the earth moves slowly and at the same speed as us
because you are moving at the same speed - relatively, you are standing still. you are small, the earth is BIG.
We don't feel the Earth rotating, because we're rotating with it. If it stopped or sped up, we would certainly feel it. It's like riding in a car; when the car is going straight on a smooth road at the same speed, we don't feel it; only when we turn or slow down or speed up.
You can't feel speed. You can only feel changes in speed. That's how you're able to read a book on a moving train, and have a comfortable nap on a jetliner flying 7 miles above the ground at 400 mph.
The air around us rotates with the Earth and we also rotate with the Earth at the same rate. There is literally nothing to feel.
In general, you can't feel speed - only changes in speed (acceleration). "Acceleration" in physics includes a change of direction. So, the Earth's orbit involves acceleration. However, the acceleration is too slow to be felt.
Because the Earth is travelling at a constant speed. i.e. it is not accelerating. Another example of this can be found in the car. When the car is accelerating, we can feel ourselves being pushed into our seats, but when we are travelling on a motorway at the same speed, we do not get this feeling.
