I have a general physics question that has been bugging me for a while. I should point out that I'm not a pysicist, so any answers need to be in very simple noddy terms that any idiot can understand. My questions is this: If I throw something into the air it comes back down in my hand. If I were able to throw it a really long way into the air, exactly perpendicular to the ground, would it still come back down in my hand, or, would the Earth have spun a little causing it to drop somewhere else? I asked this to a friend who has some physics training and he suggested it would come back down in my hand still becuase of the atmosphere. Is this correct? My real reason for asking is that everytime I get on a Jumbo Jet to travel accross the Atlantic I wonder if the spin of the Earth makes the trip home to London quicker, and if so by how much? Thanks to anyone who can explain this to me.
