Vectors and Scalars

A vector is a quantity with magnitude (size) as well as direction

A scalar is a quantity that does not have direction only magnitude

Examples of scalars: Speed - Change of distance per time (m/s) , Time, Length

Examples of vectors:

Displacement : Distance in a given direction

Velocity : Speed in a given direction, and is defined as the change of displacement per unit time (m/s)

Acceleration : Acceleration is the change of velocity per unit time M/s2
