Resolving vectors into components, adding them head-to-tail and by calculation, and finding the resultant force acting on a body.

Vectors in two dimensions combine to a single resultant that has the same effect as all of them together.
About 3 minAny vector can be split into perpendicular components, which turns two-dimensional problems into two one-dimensional ones.
About 3 minAn object in equilibrium has zero resultant force, so the components must cancel.
About 3 minOn a slope it is far easier to tilt the axes so one lies along the incline.
