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.
When an object is at rest, it is only at rest compaired to the observer. Consider that if you are in a moving vehicle then your passenger is at rest from your point of view, but to an observer, outside the vehicle the passenger and you are both in motion. Similarly to you inside the vehicle the observer outside is moving . as the earth itself is in motion, as well as the sun and in fact the whole galaxy, their is no way to absolutely define an at rest state, so all motion is measured relative to the observer, who is assumed to be at rest compaired to the observation.
In common terms, that means that it is moving.
An object is in motion if it changes position relative to a reference point. Motion is a relative quantity and is expressed in respect to the position of another object. Example: both a car and the Earth are moving (earth is revolving around the sun) but if we express the motion of the car in respect to the Earth, we say the car is moving relative to the Earth. At the same time the earth is moving relative to the sun.
A body is said to be in motion when it changes its position with respect to its immediate sorroundings and it is at rest when it does no changes its position with respect to its sorroundings (immediate).
Think of two cars driving down a highway in the same direction. One is going 30m/s, and one is going 50m/s. The faster car is going 20m/s relative to the slower car.We can basically think of relative motion as motion of one object compared to that of another object.
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.

All motion is relative. The question "is this object moving?" is in fact meaningless unless we specify "moving relative to what other object". Similarly, there is no such thing as "absolute rest": it's just as true to say that the road is moving at 50 km/h relative to your car as it is to say that your car is moving at 50 km/h relative to the road.
When its position is changing relative to our position. Note: all motion is relative to something else.

Yes and no. All motion is relative. When you say you are moving you mean in relation to something else. If are on the train and you choose something that moving alongside you at the same speed (another train for instance) then you are not moving relative to that, however you are moving in relation to the countryside. Both trains are moving in relation to a cow in the field.
If we're in the realm of newtonian physics I would say that it couldn't be in motion relative to a reference point, of course quantum physics and seems to prove everything we believe wrong.
The law states "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
