are used to describe situations where several forces act on an object. Vector diagrams are used to resolve (break down) a single force into two forces acting at right angles to each other.

The diagram above represents a vector. The arrow displays its direction, hence this vector can be written as \(\overrightarrow {AB}\), a, or \(\begin{pmatrix} 3 \\ 4 \end{pmatrix}\). In print ...
