Differences in position in 2 very similar circumstances

  1. Mar 2, 2013 #1
    I recently read in a book that if i am standing on the top of a moving train and i jump in the air i will land behind my original position. But if i am inside the train and i jump i will land exactly where i was originally!!! Is this true?? And if it is, then why does this happen???

    Think "air resistance". What is the difference between you riding in a car with all the windows up, and opening a window and sticking your hand out?
