I'll show you how to visualize which direction a cross product will point. 2:10 We drill and practice visualizing cross products. This video will help you gain a conceptual understanding of cross products and become able to quickly figure out which way a cross product of two vectors will point. In the video, I discuss the DIRECTION, but not the MAGNITUDE. The magnitude of A cross B is easily found by taking (Aperp)B, in which Aperp is the component of A that is perpendicular to B. Likewise, you can also find the magnitude of A cross B by taking A(Bperp) in which Bperp is the component of B that is perpendicular to A. #math #crossproduct #vector #apphysics
