**Vector quantities**

A vector quantity has a size (magnitude) and a direction

Examples of vector quantities include:

- Displacement (m)
- Velocity (m/s)
- Current (a)
- Acceleration (m/s2)
- Force (n)

In diagrams, vectors can be represented by arrows. The size/length of the arrows is directly proportional to the size of the vector.The direction of the arrow is in the direction of the vector.
