If there is no displacement then there is no work.

So when earth revolves around the sun it comes back to its position......... So will it be a work in physics

Solution

There is zero work being done, because the average motion of the earth is perpendicular to the force of gravity.
Since W=Fdcos x, when x=90, the work done is 0.

We know that everything in motion will come to rest. Our earth also start revolving. So my question is if earth start revolving, it will come to rest or not ? If yes then why and if no then why ?

Q. Earth revolves around the sun. Calculate the work done by the gravitational force, assuming its path to be circular.

So it takes $\frac{u}{g}$ secs to go up, how long will it take to come down?(as mentioned there is no air)

Since in space there is no friction, so if a body is given a force once then does it stop or does it continues to move or do work without stopping forever (until something stops it )?
