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 below shows some examples of vector quantities ... Looking for extra resources to supercharge your physics lessons? In this series of short explainer films, Professor Brian Cox ...

The free-body diagram method is emphasized. Topics include vector algebra, force, moment of force, couples, static equilibrium of rigid bodies, trusses, friction, properties of areas, shear and moment ...
