That means that there it doesn't make sense to specify an "absolute motion" - motion is always specified relative to some object (sometimes movement relative to the Earth is implied, not stated). There is no physical experiment that can tell the "true speed" of an object, so scientists conclude that there is no such thing as a "true speed".
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.
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.
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
By the relative motion of neighbour objects

Relative motion
Circumpolar motion refers to the motion of the stars relative to the viewer in a particular spot. Stars that are said to be circumpolar never cross the horizon as they cross the sky for the viewer.
Motion is relative to an observer's frame of Reference.
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.
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.
motion is realtive
Motion is not a 'relative term'. Motion is relative.The book that you're reading on the airliner while you fly to the coast ismoving at 600 mph relative to somebody on the ground. But relative toyou and your eyes, the book is not moving at all, and you have no troublereading it until you fall asleep ... in the seat which is also moving at 600 mphrelative to that guy on the ground.Now comes the kicker: What is the real speed of the book ?Answer: There is no such thing. Motion is relative. The book, and anythingelse, only ever has speed that is relative to something else. And it can easilyhave 300 different speeds, relative to 300 different other things, which are allmoving relative to each other.
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
When its position is changing relative to our position. Note: all motion is relative to something else.
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.
