# 4.1 Modelling with vectors

In Chapter 1, we used arrow representations to introduce the concept of vector quantities, and to explore some of the ways in which vectors can be manipulated and combined in order to solve models of engineering systems. Vector quantities are different from scalar quantities because they describe direction as well as magnitude. For this reason the arrow representation is useful to visually represent vector quantities.
