FORCE VECTOR DIRECTED ALONG A LINE (Section 2.8) If a force is directed along a line, then we can represent the force vector in Cartesian Coordinates by using a unit vector and the force magnitude. So we need to: a) Find the position vector, r AB , along two points on that line. b) Find the unit vector describing the lines direction, u AB = ( r AB /r AB ). c) Multiply the unit vector by the magnitude of the force, F = F u AB ....
