why we don't feel motion of the earth??

Answer 1

If you're speaking of the motion of Earth on it's axis or it's rotation about the sun, the answer is the scientific principle of Inertia, read now!

The principle of inertia is one of the fundamental laws of classical physics which are used to describe the motion of matter and how it is affected by applied forces.Inertia is the property of an object to resist changes in velocity unless acted upon by an outside force.Inertia is dependent upon the mass and shape of the object. The concept of inertia is today most commonly defined using Sir Isaac Newton's First Law of Motion, which states:

Every body perseveres in its state of being at rest or of moving uniformly straight ahead, except insofar as it is compelled to change its state by forces impressed. [Cohen & Whitman 1999 translation]

The description of inertia presented by Newton's law is still considered the standard for classical physics. However, it has also been refined and expanded over time to reflect developments in understanding of relativity and quantum physics which have led to somewhat different (and more mathematical) interpretations in some of those fields.

Answer 2

We can only feel motion, if our senses can pick it up. Our ears are dependant on the earths gravity to determine position and therefor motion. Since motion is relative and Earth is our central reference point, we can't feel the earth move. The other organ, the eyes also help sense motion. Since it takes a long time to see the effect of the Earths motion, rising of the sun, moon and the stars, our eyes can't tell motion either.

Answer 3

We don't feel the motion of the earth because we are USED to it. Humans can detect Change in movement, not constant movement.

At the equator, the earth is travelling at about 1000 mph. Why don't people feel it? Because the earth isn't changing its speed.

Now think about that, and this: what would happen if the earth would suddenly stop? Would we feel it then?

Answer 4

We are moving in the same direction as the earth.Most of Man's descriptions of movement mean that we SENSE something moving;like we see images moving outside a car window.However,with the earth,there are no real visible changes for us to refer to,except the stars.Also,we are simply too small to feel the movements of the earth.We are stuck relatively to the area of space in which we move ,which is REALLY tiny compared to the total surface area on Earth.Therefore,we don't feel anything in the same way that a grain of sand won't move when its stuck to a rotating basketball.When we are free from the earth's gravity and are high enough to get some substantial movement,we can see the earth's rotation.

Answer 5

Its all about the motion dear.....
The Laws of motion apply to everything that is on this planet and its just the energy that keeps on changing its forms....

Answer 6

Because of inertia of motion. We are moving at the same speed of earth. The atmosphere is moving. According to theory of relativity, its no way you can tell in two stationary objects related to each other are 'absolutely' stationary, as there are no absolute inertial reference frame.

Answer 7

This si because of gravity i guess.that we actually feel still while the earth is in motion.

Answer 8

because we move with it!

do you feel the motion of a train? or that of an airplane (barring air bumps)?

same for the Earth

and why do we move with it? Because of gravity, which glues us to the surface.

Answer 9

We do if it's an earthquake!
