ing the circular motion. Aleft-handed circular motion would besimilarly represented by a vectorswinging in the opposite direction.The rule for compounding two vectorsis to place the origin of one at the ter- t/minus of the other. Therefore, to com-pound a left-handed with a right-handed circular… … Figure 120 232 LIGHT OA. the point B will describe the path of a point whose motionis a combination of the two circular motions. If OA and AB areequal in length, and if they both rotate at the same rate, thispath is the straight line CD, as can be easily proved by simplegeometry. It is also easy to…
