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.
What do you observe if you see a clock on a very fast train moving by you"?
If you see a clock on a very fast train moving by you, you would observe that the clock appears to be moving faster than normal due to the train's speed. This is because of the relative motion between you and 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.
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.
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.
Which of these would have been a fittting subject for a futurist painting?
A fast-moving train. apex community (;
Why does one train seem to move when other train is already moving?
Relative motion. To talk about a train moving at a certain speed usually means that the train is moving at a certain speed relative to a stationary observer (relative to the ground). This however also means that a passenger traveling in said train would experience the ground (and every other stationary object) as the moving object. This is why a stationary train may seem to be moving to passengers of an already moving train.
Where is the place where a train would stop?
At the train station

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

Would someone walking toward the back the train have greater or lesser speed relative to yo?
Someone walking toward the back of the train would have a greater speed relative to you if you are stationary inside the train. This is because their speed would be the combination of their walking speed and the speed of the train moving forward.
What happens to the sound of a train whistle as a train approaches and passes you?
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.
