if you move 10 km north ,10 km east and 10 km south ,what is the displacement

To find the displacement, we need to determine the straight-line distance and direction from the starting point to the final point.

In this case, if you move 10 km north, 10 km east, and then 10 km south, you end up back where you started. This means that the straight-line distance from the starting point to the final point is zero.

Therefore, the displacement is 0 km.

Draw vectors to show. The displacement is 10 km to the east. The 10 km north cancels the 1-0 im south.

D = 10i + 10 -10i = 10 + 0i = 10 km E.
