Dot product gives work, ji, because it's about force and displacement in same direction—like my sewing machine motor's hum matching my foot's push for a straight stitch. Cross product gives torque, like the twisting force when my old machine's belt slips and the wheel resists—different directions altogether. Par, in my life, real work is the "phusss" of my iron settling that stitch flat, not just the maths.
