... the same place it would if the bus were at rest? Answer: In accord with Newton's first law, in both cases there is no horizontal force on the dropped pencil, so no change occurs horizontally. The dropped pencil in the moving bus simply keeps up with you as you move, not changing its velocity in the ...
