Question

1. Cesar drove his tricyle 10 kilometers north, He stopped for lunch and
drove another 8 kilometers south, What distance did he cover? What was
the displacement?

Answer 1

Answer:

Distance covered from origin towards north is 10km.

Then as he went 8km south. This means he drove back to origin.

Now

As distance is a scalar quantity, this means disatnce is the total of what he travelled. So the distance is 18km.

Displacement is a vector quantity which means it is the shortest distance from origin. Therefore it is 10-8 which is 2km.
