You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?
the person standing on the ground, the train is moving and the ground is stationary. but the person on the train looks he is stationary and the ground is moving.
If a train is speeding down a railroad track at a speed of 50 miles per hour. From whose reference point is the train not moving?
The passengers reference point ! The passengers are moving at the same speed as the train.
Describe your motion as seen from a reference point on the train then describe it from a reference point on the ground?
If you are *not* dealing with special relativity and its effects, then the answer becomes far more simple. If you are not moving and are standing on the ground, then you see a train moving past you a fast speed. In this case, the reference "frame" (not necessarily a point) is you and the object being described is the train. If you flipped the roles, then it would be someone on the train watching you as the train moves. However, since it is from the train's perspective, it does not appear that the train is moving, but rather that you are moving away from the train, along with the rest of the world that passes the train by. This is described as the train being the reference frame and you would be the object described by the train. This is, again, just Galilean relativity. Special relativity puts a few twists on it and has some additional effects.
Would you know you're moving in a train if there was no friction and you could not see out of the train ie can't see objects going past?
If the train is moving at a constant velocity, and therefore in an intertial reference frame, then, no, you could not tell that you were moving.
If you are riding on a train that speeds past another train moving in the same direction on an adjacent track it appears that the other train is moving backward. why?
because your going forward at a faster speed its hard to explain

How do you interpret a reference point?
something that stay at the same velocity...or dumbing it down :) is what an object is moving relative to something else.. so if there is a train and a girl watching the train the girl is a reference point because the train is moving relative of it
A passenger walks toward the rear of a moving train Describe her motion as seen from a reference point on the train Then describe it from a reference point on the ground?
If the train is moving at 50 mph and the passenger is walking at 2 mph, people on the train would see her moving at 2 mph, while people outside the train would see her moving at 48 mph. 50mph - 2 mph = 48 mph

What is relative distnce?
In our everyday lives, there is really no big difference between 'distance' and 'relative distance.' However, you must realize that EVERY measurement is relative. Consider this: You're on a moving train. A track parallel to you on the left is moving with your train at the same speed. Say it's really foggy and you can't make out any ground reference points other than the other train. You see no movement. That's because the relative speed between your train and the other train is close to zero. Main idea: All measurements have reference points. Relative distance isn't much different. It's just the distance of one object compared to the reference point, which is really just simply 'distance'.

because your going forward at a faster speed its hard to explain
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.
Can a body be at rest as well as in motion at the same time . explain?
Example: When train is moving a person sitting in a train is in the state of rest with respect to train but in motion with respect to person standing outside of the train.
What are examples of reference points?
A reference point is anything that is stationary. So, if you are on a train you know you have left the station because you moved away from the platform. Hence the platform was stationary.
There is a train which is moving on a straight track without any jerks or vibration. Everyone is asleep and you are awake.Doors and windows are closed. How do you know that the train is moving?
You wouldn't be able to tell. This is because you have no frame of reference to compare the motion to. You judge motion based on a point in space. If all the doors are closed, and all of the windows have shades pulled, the only points that you could compare to are ones that are moving at the same speed as you. Assuming that you feel no vibration, you couldn't tell if the train is stopped or moving. There are ways however to tell motion, just not visually. . If you have a GPS with you, you will realize that the position on the earth is changing.
