Answer 1

hi friend
here your answer looking for

this is a great question

so a body can be said in motion or in rest according to its reference point.
so it's all about the matter of reference point.

So, first let's know what is reference point?

Reference point:--reference point or observer is a point from where we notice or identify its state ( motion or rest).

so we can say that motion and rest are the relative term.It means that it is related to its surrounding.

So, a single object can be in a motion and in a rest at same time. if it is in the motion then it's depend upon its reference point or if it is in the rest then it's also depend upon its reference point.

hope you are understanding till now.

So, what do you think are you in the rest position or in motion?

Actually you are in motion also and rest also because if you are sitting if you take a reference point as your nearest book, pen, pencils, chair, table etc. then you are in the rest state.
But if you take your reference point as sun then you are in motion. as the earth used to revolve around the sun then we can say that the Earth is in the motion and you are also on the earth so you will also called as in the motion.

hope you understand all the things. so its all depends upon these reference point or observer.

hope my answer helped you a lot.
