if the earth moves around its axis and moves around the orbit of the sun why we do not feel these movements?

Answer 1

All circular motion involves acceleration and produces an inertial reaction called centrifugal force within the moving frame of reference. We don't feel the motions of the Earth because the accelerations involved are too small.

The rotation of the Earth produces an acceleration amounting to about .003g at the equator. The is measurable but too small to feel.

Answer 2

The Gravitational force of the earth acts on eerything on its surface and all that is on the surface of the earth is also moving at the speed at which the earth spins . We are riding on a vehicle that is moving at a speed of about 1106 miles per hour . Even the atmosphe is moving along the surface of the earth with the same speed .It is just like the way we travel in a bus or train or a plane.Theough in a train or bus we feel the effects of the movement due to the vibrations caused by by friction caused on the movement of the wheels of the vehicle on a hard surface of the terrain, we do not feel th movment of the atmosphere inside the vehicle ,because it also moes with te speedof thetrain or bus. In a plane , we do no felel any movement for the reason they is no contact with any surface excpt the atmosphericair . If we stretch our hand or any part of our body out from any moveing vehicle , we feel the drag of the atmospheric airbecause the air out side is moving with thespeed of he earthalone , wher as thevehicle is moving at a speed differnt speed ( either higher or lesse depending upon the direction of the movement. As regards the orbitof the earth , the speed is tremendous much more than any space craft can go and we are really travelling in a natural space craft without the special gears used for the space travel in man made crafts , as the atmosphere on the earth itself provides the conditons necessary for a space travel wih a tremendous speed of some million miles per hour in a space wher even the atmospheric resistance is totally nil and the movement is nothing but a free fall in space.

Answer 3

It is amazing when you consider that as a result of the earth's roation, we are moving at a speed of around Mach 2.

Gravity is a form of compression that is trying to make every piece of matter on the planet 1. If you allow your point of reference to be the moon, we actually appear to be part of the planret. We are very fortunate that the speed of the earth's rotation is just right to allow the friction of the compressed atmosphere to hold the atmosphere fairly steady and to hold us steady until we add additional propulsion by walking.

Answer 4

Because the force of gravity keeps us firmly planted on Earth's surface. Actually, the effect of Earth's rotation about its axis is measurable, it makes us a teeny tiny bit lighter than we would be if Earth stopped rotating. And since the speed of Earth's rotation depends on your latitude (if you're at the equator you're spinning around at 1000 mph, at the poles it's 0 mph) this teeny change in weight is different at different latitudes, and is also measurable, albeit only by very sensitive devices.

Answer 5

For the same reason that you don't feel that you're moving when you're in a vehicle (ex: car, train, plane) that's moving at a static - that is, constant - speed. If the vehicle that you're traveling in accelerates or decelerates rapidly then you feel the gravitational pull of such an action.

Answer 6

Because we're on Earth, effectively moving at the same speed as the planet.
