Split a force into components along any two given directions, and see why oblique components are not projections.

Use the dot product to find the angle between two lines and the parallel and perpendicular components of a force.

See what the dot product means: the angle between two directions and the part of a force along a line, drawn in 3D with its perpendicular part and a right-angle mark.
