That simply means that there is NO WAY to define or measure an "absolute motion".Any experiment you do will be the SAME for different observers - in the sense that it is unaffected by relative velocities.
It need not be. With respect to you, as the observer, the sun, moon and stars are moving around the earth. I hope you do not still believe in the geocentric universe!
when A is in motion with respect to B, then B is in motion with respect to A note: A and B are bodies or anything
MOTION: A body is said to be in motion if it changes it's position with respect to it's surrounding. REST: A body is said to be in rest if it does not changes it's position with respect to it's surrounding.
No. Assuming there are no eddies or crosscurrents, and it is not blown in a different direction by the wind, a leaf in a stream is being moved by the water, and would display little motion with respect to the water, as compared to its motion with respect to things not in the flowing stream.
Motion is related to a change in position of an object with respect to time. Motion is typically described in terms of velocity
movement or motion

With respect to a state of rest or apparent rest.
a object is said to be motion if it position with respect it changes with time
MOTION: A body is said to be in motion if it changes it's position with respect to it's surrounding. REST: A body is said to be in rest if it does not changes it's position with respect to it's surrounding.
motion : when a body is moving or changing its position with respect to its surroundings is called motion. rest: when a body is not moving or fixed at a place with respect to its surroundings is called rest.
When an object changes its position with respect to time, then the body is said ti be in 'motion'. When the body is at rest, it is state of 'no motion'.
No. Assuming there are no eddies or crosscurrents, and it is not blown in a different direction by the wind, a leaf in a stream is being moved by the water, and would display little motion with respect to the water, as compared to its motion with respect to things not in the flowing stream.

You observe its motion, with respect to the background stars.
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.
when position of the body with respect to an observer change with time then the body are said to be in motion.
