What else can I help you with?
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?
When looking out the window, if you focus on a distant building outside the train, it may appear that the train is not moving because the building is not changing position relative to the train. However, if you look at a nearby platform or another train beside yours, you may notice the train's movement compared to these closer reference points, making it appear that the train is indeed moving.
What is the motion of the train on a moving track?
The motion of a train on a moving track depends on the reference frame you choose. In the train's frame of reference, it may appear stationary or moving at a constant speed. However, in an external, stationary frame of reference, the train would appear to be moving at a different velocity that combines the train's speed with the speed of the track.
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?
No, without any external reference points to visually determine movement, you would not be able to perceive that you are moving on a train if there is no friction. The lack of friction would eliminate the physical sensations typically associated with movement.
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.

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'.
Can a body be at rest as well as in motion at the same time . explain?
No, a body cannot be at rest and in motion at the same time in the same frame of reference. This is known as the principle of relativity in physics, which states that an object cannot have multiple velocities at the same time in a single reference frame.
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.
Can a train appear to be at rest while moving?
Yes, a train can appear to be at rest when viewed from within the train itself, as there is no external frame of reference to gauge its motion. This is similar to how you may feel stationary while sitting on a train that is already moving, until you look out the window and see the surrounding landscape passing by.
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.
