The passengers reference point ! The passengers are moving at the same speed as the train.

Does motion have to be measured relative to a frame of reference?
Because motion only exists relative to something else. when measured from different reference frames, the same motion will appear to have different speeds, accelerations, and directions. And the thing of it is ... they'll all be correct !
Why do you need to use a reference point to tell if an object is in motion?
Because there's no such thing as "real" motion. There's only motion compared to something else. You can't read a book if the book is moving. But you can read just fine while you're traveling in an airliner. Compared to your lap and your eyes, the book is not moving. Compared to the librarian that you're flying over, you and the book are both moving at 400 miles an hour. Well, which is it ? Is the book motionless or is it moving at 400 miles an hour ? The answer is: Yes. It's both, depending on the reference point.
Direction and velocity are what to a frame of reference?
Frame of reference is related to motion because reference points enable us to see that an object is moving. ======================== Motion is related to a frame of reference because there is no such thing as 'real' motion or 'real' rest. 'Rest' and 'motion' are always with reference to something else. The book that you are reading is at rest with reference to your lap, your lap is at rest with reference to the seat you're sitting in, and you, the book, and the seat are all at rest with reference to the airplane you're flying in at 400 miles per hour. See what I mean ?
How could you be moving in one frame of reference but not in another?
Here's one example. Suppose you're on a train. Now let's further suppose this is a very smooth-riding train and that the windows are covered up and you've never been on a train before. As long as the train is going straight (no curves, no hills) and not accelerating or decelerating, it would be very difficult for you to tell you're moving relative to the outside world: everything in the train is moving at the same speed you are, or, to put it another way, you're all in the same frame of reference. That frame of reference may be moving 60 miles per hour relative to the outside world, but everything you can see or measure appears to be standing still.

Does the reference point depend on motion?
If you're reading a book in an airplane and it happens to fly over your friend's house,your friend says that the book is moving at 350 miles per hour. But at the same time,you say that the book isn't moving at all, and that's why you're able to read it easily.You and your friend are both correct. In his reference frame, you and the book are bothmoving at 350 miles per hour. In your reference frame, the book isn't moving at all.
