###### Topic Notes

The notion of vectors can be easily found in our daily surroundings – from airplane navigation to trajectories of balls during a sports game, to movements of a character you maneuver in your video games. In this section, we will learn about the graphical, and mathematical representation of a vector, as well as how to distinguish the differences between a scalar quantity and a vector quantity.

Vector Quantity: a quantity having (positive) magnitude and (one) direction

Scalar Quantity: a quantity having only magnitude but not direction

Two – Dimensional Vectors:
