Title: C=AXB cross product vector relationsPost by: Fu-Kwun Hwang on February 23, 2007, 08:45:08 pm
Drag vector A or B to see how the vector C=AXB changed!
The magnitude of the cross product |C| = |A| |B| sinθ which is equal to the area span by vector A and B =>light gray area shown in the program (also equal to length of the blue arrow). -*- [ejsapplet] Examples of C=AXB 1. F=q v X B: charged particle with charge q , velocity v moves in the magnetic field B.2. L = r X P: angular momentum L, linear momentum P You will find many similar relations in physics. |
