Question

an object goes from point x to y and then come back from y to x what is the displacement and average velocity ?

Answer 1

Displacement is zero because initial and final position are same.
Average velocity = displacement ÷ time
here, displacement is zero and eventually any number divided by zero gives us zero as answer.
Therefore, average velocity= 0

Thus ,
Displacement. = 0
Average velocity=0

Answer 2

SOLUTION :

To solve this question, we have to know what actually displacement means ! Dipslacement is the shortest distance between the starting and the ending point.

Now, in the question, the starting and the ending point is the same one, so the displacement will be zero.

We can write that, the ratio of displacement to time gives us the average velocity. So in this case, the average velocity will be zero as displacement is zero.
