Question

What is the displacement for a driver who travels 10 km to get to a point that is 4 km from his starting point?

Answer 1

The displacement is square root of (4^2 + 2^2)= sqrt (20)= 2sqrt(5)

Answer 2

The displacement is the shortest path which is final point minus initial point.It is a vector quantity which has magnitude and direction.

Distance is the path travelled is a scalar quantity.

Here, Say A is the starting point and He has covered total 10 km which is 4 km from the initial point

Hence, Displacement is 4 km which is the difference of final and initial point.
