It's all in your "frame of reference". If you're in a train - say, in the baggage car, where there are no windows, and the track is smooth and straight and the shock absorbers and springs are REALLY good - then you may not be able to feel or see any motion. Your "frame of reference" is that baggage car. You are at rest.
If you go up to the normal car and sit in your seat and look out the window, then your "frame of reference" is large enough for you to see the movement; you are in motion.
We sometimes get motion sickness when we have TWO frames of reference imposed on us at once; we're in an airplane with the window curtains closed, so we SEE that we're at rest, but we can FEEL the movement of the airplane. Our brains get confused, and we get sick.
yes, a train in which you are sitting appears to move while it is at rest, because of relative term as motion & rest are relative term . Actually it is depend upon observer. Example- If a boy sitting in train, when he see a man moving outside the train, it seems to him that it is in motion.
rest and motion are indeed relative terms take for example, you are standing on a platform and see a train speeding past you. the train is definitely in motion with respect to you. now, think of a passenger in the same train..to the passenger the train in at rest but he sees the platform speeding past him, meaning you appear to be in motion with respect to him... this concept is very much relative, as the earth like all the other planets including the sun are actually moving. so though the computer in front of you may seem to be at rest with respect to you, it is actually in motion if someone from the moon or some other planet sees it...:-)
Newton’s First Law of Motion states that every object will remain in a state of rest or travelling with a constant velocity unless an external force acts on it.
The train, on account of being the heaviest.
An object can be at rest relative to a second object whilst in motion relative to a third object.For example, if you sit still then relative to the Earth you are at rest. However the Earth is both spinning on its axis and travelling around the Sun, so relative to an observer in space you are in motion. Einstein showed us that all such concepts are relative.
At rest and in motion are relative terms. When we say 'in motion' or 'at rest' we mean relative to something else. If you were travelling in a car for instance, you would be at rest relative to the car but in motion relative to the outside world.
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.
He is in motion relative to me, and he is at rest relative to his friends. There is no 'real' rest or 'real' motion. It's always measured relative to something else.
acceleration is a relative quantity . state of rest or motion is also relative . if two body is in rest or moving with same velocity and having same acceleration then one is in state of rest with respect to other . suppose a person sitting in a train then he is in rest with respect to train but he is moving with the acceleration of train with respect to the ground.

Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by an external force. In simpler terms, an object will remain in its current state of motion (or lack thereof) unless something forces it to change.
