but when we take a helicopter above the surface and we r in us and earth rotates so we can easily reach to japan then y do we move our helicopter to go to japan

When earth rotates, so does everything which is on the surface of earth, including the helicopter when on ground and the air above it. If this was not so, you will feel the air blowing at a speed of about 4 km / second !!
So, when we lift the helicopter, it is already rotating at the same speed as the earth. so, no advantage as you say.
We will remain where we are.

That's a problem in fuel consumption and relativity. You need a relative point of reference. When a helicopter hovers it attempts to stay over one spot. You would have to fix on the Sun and possibly the Moon and keep them in the same spot. Then in 12 hours or so Japan would be somewhat near you.
The problem is most helicopters can't fly for 12 solid hours and holding a fixed hover is extrmely boring and difficult.

good question. I wish I had a good answer to go with it. This has been blowing my mind since I was a little kid. Yep the atmosphere spins with the earth. seems there is some drag on the atmosphere that causes the prevailing winds to be from the west. What's bothersome for me is gravity behaves as if it's stationary relative to satellite orbits. a warp in space caused by mass they say. The spin of the earth doesn't effect satellite orbits (Maybe a little but I didn't see the term in the equations for orbits). speed up slow down the spin the satellite orbit remains the same.

halicopter will not come out of gravitational field of earth even after it rises above the surface of earth.so it also rotates with earth with the same speed of earth and there is not any relative velocity b/w earth and helicopter. therefor we move our helicopter to go to japan.

It is coasting forever in the frictionless vacuum of space on the momentum it got when it was formed billions of years ago. There is no power source. None is needed since there is no friction to slow it down. (Actually, there is a small amount of friction due the the Moon and the tides, and that slows Earth's rotation by a very, VERY small fraction of a second each year.)

Do you speak English and where were you educated? The earth Has an Atmosphere. When you leave the atmosphere you'll see the earth rotating. Have fun getting your helicopter outside the atmosphere ..you'll burn up.

The atmosphere rotates with the solid part of the Earth. If it didn't you would feel a thousand mile per hour wind all the time.

provided there is a question here. the earth moves too slowly for your idea to work. the helicopter would run out of fuel before it got there.

same reason you don't go flying off to east at 1 a thousand miles an hour when you jump off the ground ... you are already moving with the same velocity as the surface of the earth, so there is no

Gravity is the answer. When the Earth rotates, it moves everything within its gravitational pull aslong with it.
