So that you follow the right path and do not get misled
We need compass to know the direction we are going.
Direction and magnitude.
"North" is a valid direction, but for a vector, you would also need a magnitude.
you don't need to stir flour in one direction
you need to install idler gear or remove idler gear depend on the engine to counter the direction also you need to change the engine oil pump direction and you need to change the cam shaft directions
Vectors need both magnitude and direction.

To find the velocity, you need to specify a direction. If you just need the speed, the velocity is 15 km/hr. If you need the velocity including direction, you need to provide information about the direction (e.g., north, east, etc.).
These are line segments that are the same in direction and length. * * * * * They need not be in the same direction.
you need more information.
no!
You need a compass rose so you know which direction the map is. Without knowing the direction of the map you will be going in the wrong direction.
