If an object moves 40 m north, 40 m west, 40 m south, and 40 m east, what's the total displacement?
40 m, 0 m, 80 m, 160 m

Solution:

Let the object start to move from point X in the north direction

The path is shown in the image below:

We have to find the displacement of the total path

Displacement is defined as the difference of the final destination and the initial destination

Here the initial destination is point X and the final destination after completing the path is also point X.

∴ the displacement of the object will be the distance of point x to the point x which is 0

∴ the displacement will also be equal to 0 m .

If an object moves 40 m north, 40 m west, 40 m south, and 40 m east, what's the total displacement?
40 m, 0 m, 80 m, 160 m

Summary:

When an object moves 40 m north, 40 m west, 40 m south, and 40 m east, the total displacement of the object is 0 meter.
