Have you ever wondered? 1. Why do airplanes take longer to fly west than east? It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from   London to NY. The reason for the difference is an atmospheric phenomenon known as the jet   stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction. 2. What would happen if the gravity on Earth was suddenly turned off? Supposing we could magically turn off gravity. Would buildings and other structures   float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string  , it goes around in a circle until you let go of the string. Then it flies off in a straight line. 'Switching off' gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly _ upwards at a great speed until they hit the ceiling. Most things outside would fly off into space. It can be inferred that without gravity   _  . A) buildings and other structures would float away B) trees and buildings would not so easily fly off C) something around your head would not float away D) everything outside buildings would fly off into space
