I am not sure if this is the correct subforum to ask this question . My apologies in advance . Consider a helicopter 'floating' at a certain height from the ground and it's stationary , say if it's in London , would it still be in London after 12 hours ? Since the earth is rotating , would it still be in the same place as where it was initially ? We are actually moving as the earth rotates because we are in contact with the ground but this time the helicopter isn't ?
