Vectors | Vector Properties | Vector Mechanics

A vector refers to any quantity that needs magnitude and a direction in order to fully describe the quantity. In this lesson, you will learn about the properties of vectors (magnitude and direction) and how to determine what quantities are vectors and what are not vectors.

When someone tells you to throw a ball twice as hard and to the left, a vector was just used. When someone tells you to drive northeast for about five miles, a vector was just used. So what exactly is a vector? Any quantity that needs to be fully described by identifying its magnitude and direction is referred to as a vector quantity. By magnitude, we mean the size of the quantity, such as length or strength. By direction, we mean where the vector is pointing or where it is being directed, such as left or right, north, south, east, or west, or even up or down.
