Answer 2

Answer:

For that we have to know what displacement is. When an object is moved from the one place to another without returning or the amount of surface covered in a “t” period of time.  

Explanation:

Now there are instances when the displacement can be zero, i.e. if the displacement happens in a circular position or if the user returns back to its primary position, although in practicality there was movement but in physics, the displacement is zero. Therefore, to make displacement count one should prevent returning back to the same point as they have started only then displacement is taken into account.
