No rest or no motion is absolute Explain it.

Ans: Whether an object is actually in rest or motion depends on the reference object. If the reference object or reference frame is actually at rest, the object at rest will be actually at rest with respect to that frame. This type of rest is called absolute rest. A body is said to be in absolutely rest when it is at rest with respect to an absolutely rest object.

But in this universe it is not possible to get a reference object which is at absolute rest. Since the earth is moving around the sun while the sun itself is moving along the galaxy with its planets and satellites. So, we can say that in this universe all rest and all motion are relative. No rest or no motion is absolute.
