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).

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

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.
