Motion is relative to your frame of reference which you can choose arbitrarily.
Most people use the surface of the earth as their frame of reference or their own body depending on the calcualtion they are doing. However, that makes describing the orbits of the planets more difficult so the sun is often used as the frame of reference in that case. If I'm inside a car my frame of reference might be my head, the car or I could choose a spot along the road (the surface of the earth).
From a science standpoint you should get the same answer no matter what frame of reference you arbitrarily choose but it often turns out that choosing a particular frame of reference makes certain calculations much easier.
Just keep in mind that motion is always relative to something and you get to pick whatever that something is when you are solving a problem or doing a calculation. Just don't change frames of reference in the middle of a problem or your answer will likely be incorrect.
What else can I help you with?
Does friction oppose motion or relative motion of surface in contact?
Friction opposes the relative motion of surfaces in contact. It acts in the direction opposite to the direction of motion or tendency of motion between two surfaces.
What is meant by the statement rest and motion are relative terms give example to show it?
The statement "rest and motion are relative terms" means that whether an object is considered at rest or in motion depends on the observer's frame of reference. For example, a person sitting on a bus is at rest relative to the bus, but in motion relative to a person standing on the street. This illustrates that rest and motion are relative concepts.
When an object changes position over time relative to a reference point the object is?
The object is in motion relative to the reference point.
All motion is relative to what?
All motion is relative to yourself, as there is no fixed point anywhere in our universe, as it is all traveling away from the center of the big bang. But if we ever find where the bigbang happened, that would be where all motion is relative to
What is the definition of the word relative motion?
Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
Does friction oppose motion or relative motion of surfaces in contact?
Relative motion
Does friction oppose motion or relative motion of surface in contact?
Friction opposes the relative motion of surfaces in contact. It acts in the direction opposite to the direction of motion or tendency of motion between two surfaces.
Motion relative to observers frame of?
Motion is relative to an observer's frame of Reference.
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.
Is motion relative or absolute?
motion is realtive

When we can say the object is in motion?
When its position is changing relative to our position. Note: all motion is relative to something else.
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.
What is the definition of the word relative motion?
Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
What is definition of relative motion?
Comparing one motion to another.
