Rest and motion are observed by some specific observer. That observer is at rest in his or her own reference frame, but would be moving in some other observer's reference frame. So if two different observers are not at rest with respect to each other, then they also would get different results when they observe the motion (or lack of motion) of anything else.
A simple example would be, imagine that someone is in a car, driving at 30 miles per hour. He (or she) has a drink in his (or her) cup holder. It sits there right next to him (or her), not moving. An external observer (someone who is not in the car) would observe the same drink going by at 30 miles per hour. Similarly, a person sitting at home in his or her house seems not to be moving, as observed by anyone else in that house, or by someone in another house or by someone walking by on the street. However, we also know that the planet Earth rotates on its axis once a day, and revolves around the sun once a year, and so everything on the surface of the Earth is moving, as viewed from another planet such as Mars, or from other extraterrestrial viewpoints.
So you never know how anything may be moving or not moving, unless you have established a frame of reference. This has been explained in Einstein's special theory of relativity.

Are motion and rest relative terms?
Yes.
How can you say that rest and motion are relative terms?
a body is said to be at rest if it does not change its position relative to a reference frame similarly a body is said to be in motion if it changes its position relative to any reference frame.
Prove that rest and motion are relative terms?
Actually sitting on the earth we feel as if we are at rest. But relative to the pole star we are moving along a circular path. Also relative to the sun we are moving along an elliptical path around the sun. So actually speaking we are not at rest. In the same nothing is stationary. Everything is in motion. Rest means only a relative term.
Difference between rest and motion?
Actually very difficult to determine, as the whole universe is in motion. One usually refers to relative rest or relative motion.
Can an object be at rest as well as in motion at same time?
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.
A body which is in both rest and motion?
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.

What is your idea about G person who travelling with his friends in a cartis he in motion or in rest?
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.

Why are rest and motion called relative term?
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...:-)
Is the walls of room at rest or at motion?
rest or motion is a relative concept,if u r on earth dn its in rest n if u r at some other planet then wrt it is in motion
