Our Earth is spinning, right?

If someone floating on land and the earth rotates whether that person is still floating and the earth rotates and causes the person is on the move. or the person flying it will follow the rotation of the earth without causing the move?

a steel ball dropped from a helicopter. helicopter that dwell on the earth's surface has the same rotational speed with the earth so that the ball is dropped also had the same rotational speed. the views of people standing on the earth, the ball fell straight. if the ball was given sonar, and sonar luarangkasa observed from the station (the station in space velocity is relatively unaffected by movement of the Earth's rotation), it would appear the ball would have a parabolic trajectory. nah this phenomenon is a phenomenon called frame of reference. trivial.

It spins no doubt. Well if we are flying (well, dapaet knowledge of where to drift, losing to David Copperfield) we will not experience a shift in position as long as no external forces acting on us (essentially we just drift only, not the streets). This is related to Newton's law of inertia. Confused ?????? asked only to Newton and Einstein, they are experts in the inertial frame and inert framework.

Surely people who drifted such as those mini-vertical jump or rocket or any other position from the ground, the rocket will not move the position as assumed that the earth rotates underneath. Of course, rotation speed of air and any objects on the surface of the earth are equal and uniform, so that if we throw stuff at the top, its velocity relative to the Earth's surface will remain the same and not the earth spins faster at the bottom. But if the throw distance is very much like thousands of kilometers into the earth's surface, then the effect may occur due to the effects of gravity gradient, etc.
