Forces, velocities, accelerations.
An airplane flying in a specific direction at a specific speed.
Any measurement in which the direction is relevant requires vectors.
Roads are an example of intersecting lines in the real world.
Equations are used to give a mathematical analysis of events or situations in the real world.
In real life unit vectors are used for directions, e.g east, north and up(zenith). The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level. Whenever and where ever location is important, unit vectors are a part of real life. Whenever directions are important in your real life, then unit vectors are important. If everything was confined to move along a straight line, then unit vectors would not be important. If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors.
Real world uses for vectors would be plotting courses for boats and planning the construction of roads
